Title of Invention: INKJET PRE-TREATMENT FLUID FOR TEXTILE PRINTING Abstract: An inkjet pre-treatment fluid for textile printing includes a fixing agent including a multivalent metal cation; and a blocked polyisocyanate selected from the group consisting of a non-ionic blocked polyisocyanate, a cationic blocked polyisocyanate, and an anionic blocked polyisocyanate having an acid number less than 5 mg KOH/g. The inkjet pre-treatment fluid further includes a liquid vehicle. Detailed Description: BACKGROUND Textile printing methods often include rotary and/or flat-screen printing. Traditional analog printing typically involves the creation of a plate or a screen, i.e., an actual physical image from which ink is transferred to the textile. Both rotary and flat screen printing have great volume throughput capacity, but also have limitations on the maximum image size that can be printed. For large images, pattern repeats are used. Conversely, digital inkjet printing enables greater flexibility in the printing process, where images of any desirable size can be printed immediately from an electronic image without pattern repeats. Inkjet printers are gaining acceptance for digital textile printing. Inkjet printing is a non-impact printing method that utilizes electronic signals to control and direct droplets or a stream of ink to be deposited on media. BRIEF DESCRIPTION OF THE DRAWINGS Features of examples of the present disclosure will become apparent by reference to the following detailed description and drawings. FIG. 1 is a flow diagram illustrating an example of a printing method; FIG. 2 is a schematic diagram of an example of a printing system; FIG. 3A is a black and white reproduction of an originally colored photograph of a textile swatch printed without a pre-treatment fluid and with a yellow pigment inkjet ink and a black pigment inkjet ink, showing black to yellow bleed; and FIG. 3B is a black and white reproduction of an originally colored photograph of a textile swatch printed with an example of a pre-treatment fluid and with a yellow pigment inkjet ink and a black pigment inkjet ink, showing improved black to yellow bleed. DETAILED DESCRIPTION Examples of the pre-treatment fluid disclosed herein can be applied digitally, via a thermal inkjet printer or a piezoelectric inkjet printer in order to prepare a textile substrate for the subsequent direct application of a pigmented inkjet ink. The pre-treatment fluid may be applied digitally, which avoids the use of spray nozzles, roll-coating, cylindrical pad printing, or other analog techniques. It has been found that the pre-treatment fluid disclosed herein improves the image quality of the resulting printed textile, e.g., in terms of higher optical density and reduced color bleed, and improves the washfastness of the printed textile (e.g., when compared to prints formed on similar textile substrates without the pre-treatment fluid disclosed herein). Referring now to FIG. 1, an example of a printing method 100 comprises: inkjet printing an inkjet pre-treatment fluid onto a textile substrate, the inkjet pre-treatment fluid including: a fixing agent including a multivalent metal cation, a blocked polyisocyanate selected from the group consisting of a non-ionic blocked polyisocyanate, a cationic blocked polyisocyanate, and an anionic blocked polyisocyanate having an acid number less than 5 mg KOH/g, and a liquid vehicle (as shown at reference numeral 102); inkjet printing an inkjet ink onto the printed inkjet pre-treatment fluid to form an ink layer on the textile substrate, the inkjet ink including a pigment (as shown at reference numeral 104); and curing the ink layer on the textile substrate (as shown at reference numeral 106). The curing of the ink layer on the textile substrate renders the image printed thereon durable, wash-resistant, and colorfast. In an example, the curing of the ink layer on the textile substrate is accomplished at a temperature ranging from about 80° C. to about 200° C., for a period of time ranging from about 30 seconds to about 15 minutes. In further examples, the curing of the ink layer on the textile substrate is accomplished at a temperature ranging from about 80° C. to about 190° C.; or from about 90° C. to about 165° C.; or from about 120° C. to about 160° C.; or from about 140° C. to about 150° C. In further examples, the time period during which the curing of the ink layer on the textile substrate takes place ranges from about 25 seconds to about 18 minutes; or from about 45 seconds to about 12 minutes; or from about 50 seconds to about 9 minutes; or from about 1 minute to about 3 minutes. In a further example, the curing of the ink layer on the textile substrate is accomplished at a temperature of about 150° C., for about 3 minutes. Curing may also be performed with or without the application of pressure. It is to be understood that this curing temperature range for the textile fabric 33 may vary, depending upon, e.g., the fixation temperature of the selected inkjet ink and the type of fabrics. For example, if the fixation temperature of a selected ink were 150° C., the curing temperature may be any suitable temperature at, or above, or slightly above (e.g., +5° C.) 150° C. The curing time may also vary depending on the curing temperature. Shorter time may be used if curing takes place at a higher temperature, and longer time may be used if curing takes place at a lower temperature. In a further example of the method 100, the inkjet ink is printed onto the printed inkjet pre-treatment fluid while the pre-treatment fluid is wet. Wet on wet printing may be desirable because less pre-treatment fluid may be applied during this process (as compared to when the pre-treatment fluid is dried prior to ink application), and because the printing workflow may be simplified without the additional drying. In an example of wet on wet printing, the inkjet ink is printed onto the printed inkjet pre-treatment fluid within a period of time ranging from about 0.01 second to about 30 seconds after the printed inkjet pre-treatment fluid is printed. In further examples, the inkjet ink is printed onto the printed inkjet pre-treatment fluid within a period of time ranging from about 0.1 second to about 20 seconds; or from about 0.2 second to about 10 seconds; or from about 0.2 second to about 5 seconds after the printed inkjet pre-treatment fluid is printed. In yet a further example, the printed inkjet pre-treatment fluid may be dried on the textile substrate, and the inkjet ink may be printed onto the textile substrate having the dried inkjet pre-treatment fluid thereon. It is to be understood that in this example, the textile substrate having the inkjet pre-treatment fluid printed thereon may be dried in any suitable manner, e.g., it may be air dried (e.g., at a temperature ranging from about 20° C. to about 80° C. for 30 seconds to 5 minutes), it may be exposed to electromagnetic radiation (e.g. infra-red (IR) radiation for 5 seconds), and/or the like. In a further example of the method 100, a ratio of pre-treatment fluid printed to inkjet ink printed ranges from about 1:20 by volume to about 1:1 by volume. In further examples, the ratio of pre-treatment fluid printed to inkjet ink printed ranges from about 1:15 by volume to about 1:2 by volume; or from about 1:10 by volume to about 1:3 by volume; or from about 1:7 by volume to about 1:5 by volume. In an example, the ratio of pre-treatment fluid printed to inkjet ink printed is about 1:4 by volume. An example of a liquid fluid set for inkjet printing onto a textile substrate comprises: an inkjet pre-treatment fluid 26, including: a fixing agent including a multivalent metal cation; a blocked polyisocyanate selected from the group consisting of a non-ionic blocked polyisocyanate, a cationic blocked polyisocyanate, and an anionic blocked polyisocyanate having an acid number less than 5 mg KOH/g; and a liquid vehicle for the pre-treatment fluid; and an inkjet ink 24, including: a pigment dispersion; a polymeric binder; and a liquid vehicle for the inkjet ink. Referring now to FIG. 2, a schematic diagram of a printing system 30 includes an inkjet printer 32 in a printing zone 34 of the printing system 30 and a heater/dryer 36 positioned in a fixation zone 38 of the printing system 30. In an example, a textile fabric/substrate 33 may be transported (e.g., by a platen 28) through the printing system 30 along the path shown by the arrows in FIG. 2 such that the textile substrate 33 is first fed to the printing zone 34 where an example of a pre-treatment fluid 26 is inkjet printed directly onto the textile substrate 33 by the inkjet printer 32 (for example, from a piezo- or thermal-inkjet printhead). In an example, the printing of the pre-treatment fluid 26 forms a pre-treated area on the textile substrate 33. Then a pigmented inkjet ink 24 is also inkjet printed, over the pre-treatment fluid 26 onto the textile substrate 33 (e.g., onto the pre-treated area) to form an ink layer on the textile substrate 33. The textile substrate 33 having the pre-treatment fluid 26 and the ink layer disposed thereon may then be transported to the curing/fixation zone 38 where the ink layer is cured, e.g., by exposure to heat 44. The curing/fixation zone 38 may include a clam shell hot press, an oven, or a conveyer dryer. In an example, the exposing to heat accomplishes curing/fixation of the inkjet ink 24 onto the textile fabric 33, to form a printed image 37. The curing/fixation of the ink 24 (causing it to bind onto the textile substrate 33) forms a printed article 40 including the image 37 formed on the textile substrate 33. An example of the printing method 100 further comprises maintaining the pre-treatment fluid 26 separate from the inkjet ink 24 until they are inkjet printed. In some examples, the heater/dryer 36 may be positioned to apply heat 44 to the textile substrate 33 immediately after the pre-treatment fluid 26/ink 24 has been applied thereto. In the example shown in FIG. 2, the heater/dryer 36 is disposed in the curing/fixation zone 38, which allows for printing and curing in a single pass. In an example, the heater/dryer 36 may be moved or scanned across the printed image 37 in the curing/fixation zone 38. In another example, the heater/dryer 36 may be in a fixed position with respect to the textile substrate 33. The heater/dryer 36 may be a conductive heater or a radiative heater that is part of, and/or connected to the printing system 30. These types of heaters may be placed below the textile substrate 33 or may also or alternatively be placed above the textile substrate 33. In the examples disclosed herein, printing of the pre-treatment fluid 26 and of the ink 24 may be accomplished without warming/pre-heating the textile substrate 33. As such, printing of the fluids may be accomplished at room temperature (e.g., about 18° C. to about 25° C.), and then drying or drying and curing may be accomplished at the elevated temperatures disclosed herein. In an example, if the amount of time and the temperature at which the fabric 33 having the pre-treatment fluid 26 and ink 24 thereon is cured is enough to fix the ink 24 onto the fabric 33, warming may not be performed. Another example of the printing method 100 further comprises warming the textile fabric 33 having the pre-treatment fluid 26 and the ink 24 thereon at a temperature below a fixation temperature of the inkjet ink 24: i) before the curing; or ii) concurrently with the curing; or iii) both before and concurrently with the curing. It is to be understood that the warming may be accomplished by exposing to electromagnetic radiation. The source of electromagnetic radiation may be infrared (IR) or near-infrared (NIR, near-IR) light sources, such as IR or near-IR curing lamps, lasers with the desirable IR or near-IR electromagnetic wavelengths, or any combination thereof. In an example of the printing method 100, the temperature at which the textile fabric 33 is warmed ranges from about 60° C. to about 100° C. In another example, the temperature at which the textile fabric 33 is warmed ranges from about 70° C. to about 90° C. It is to be understood that this warming temperature range may vary, depending upon, e.g., the fixation temperature of the selected inkjet ink. For example, if the fixation temperature of a selected ink were 160° C., the warming temperature may be any suitable temperature below 160° C. In an example of the printing method 100, the warming takes place for an amount of time ranging from about 0.1 seconds to about 30 seconds. In another example, the warming takes place for an amount of time ranging from about 3 seconds to about 18 seconds. In yet another example, the warming takes place for an amount of time ranging from about 1 second to about 5 seconds. It is to be understood that this warming time range may vary, depending upon, e.g., the temperature at which warming takes place. For example, if the warming temperature is at a higher end of a range, the time for warming may be at a lower end of a range. Pre-Treatment Fluids In the examples of the method 100 and the system 30 disclosed herein, and as mentioned above, an inkjet pre-treatment fluid 26 may be used. An example of an inkjet pre-treatment fluid 26 for textile printing comprises: a fixing agent including a multivalent metal cation; a blocked polyisocyanate selected from the group consisting of a non-ionic blocked polyisocyanate, a cationic blocked polyisocyanate, and an anionic blocked polyisocyanate having an acid number less than 5 mg KOH/g; and a liquid vehicle. In an example, the blocked polyisocyanate is a blocked polydiisocyanate. In a further example, non-ionic blocked polydiisocyanates are used. In yet a further example, cationic blocked polydiisocyanates are used (e.g., a blocked polydiisocyanate dispersed by cationic groups). In an example, the multivalent metal cation is selected from the group consisting of calcium cations, magnesium cations, zinc cations, iron cations, aluminum cations, and combinations thereof. In a further example, the fixing agent comprises a metal salt and further includes anions selected from the group consisting of chloride anions, iodide anions, bromide anions, nitrate anions, carboxylate anions, sulfonate anions, sulfate anions, and combinations thereof. It is to be understood that the metal salt (containing the multivalent metal cation) may be present in any suitable amount. In an example, the metal salt is present in an amount ranging from about 2 wt % to about 15 wt % based on a total weight of the pre-treatment fluid. In further examples, the metal salt is present in an amount ranging from about 4 wt % to about 12 wt %; or from about 5 wt % to about 11 wt %; or from about 6 wt % to about 10 wt %, based on a total weight of the pre-treatment fluid. In an example of the inkjet pre-treatment fluid 26, the blocked polyisocyanate is present in an amount ranging from about 0.2 wt % to about 15 wt % based on a total weight of the pre-treatment fluid. In further examples, the blocked polyisocyanate is present in an amount ranging from about 1 wt % to about 10 wt %; or from about 1.5 wt % to about 5 wt %; or from about 2 wt % to about 3 wt %, based on a total weight of the pre-treatment fluid. In an example of the inkjet pre-treatment fluid 26, the blocked polyisocyanate includes blocking groups selected from the group consisting of phenols, ϵ-caprolactam, butanone oxime, diethyl malonate, secondary amines, 1,2,4-triazoles, pyrazoles, and combinations thereof. Butanone oxime is also known as methyl ethyl ketoxime. An example of a suitable pyrazole is 3,5-dimethyl pyrazole. The term “blocked polyisocyanate” refers to compounds with multiple isocyanate groups where a plurality of the isocyanate groups are coupled to a chemical moiety that stabilizes the isocyanate groups in the inkjet pre-treatment fluid 26 so that they remain available for reaction after printing on the textile fabric 33. The chemical moiety that prevents the isocyanate groups from reacting can be referred to herein as a “blocking group.” To convert the blocked polyisocyanate to a reactive species, the blocking group can be dissociated from isocyanate groups to result in a “deblocked polyisocyanate.” Deblocking can occur by heating the blocked polyisocyanate to a temperature where deblocking or dissociation can occur, e.g., typically at from 100° C. to 200° C. There may be deblocking or dissociation temperatures outside of this range, e.g., at lower temperatures. In an example, the blocked polyisocyanate is non-ionic and has an acid number ranging from 0 mg KOH/g up to 1 mg KOH/g. In one example, the non-ionic blocked polyisocyanate can include a blocked polyisocyanate trimer. The blocked polyisocyanate trimer can have the structure shown in Formula I, as follows: (NCO)3R3(NHCO)3(BL)3-X(DL)X Formula I where R can independently include a C2 to 10 branched or straight-chained alkyl, C6 to C20 alicyclic, C6 to C20 aromatic, or a combination thereof; BL can include a blocking group such as a phenol blocking group, a lactam blocking group, an oxime blocking group, a pyrazole blocking group, or a combination thereof; x can be from greater than 0 to 1; and DL can include a non-ionic hydrophilic dispersing group, such as a polyethylene oxide group, a polypropylene oxide group, or a combination thereof. In one example, R can be from C4 to C8 alkyl and BL can be a dimethyl pyrazole. An example of a blocked polyisocyanate that can be used is Matsui FIXER™ WF-N (a 3,5 -dimethyl pyrazole non-ionic blocked polyisocyanate commercially available from Matsui Shikiso Chemical (Japan)). Another example of a non-ionic blocked polyisocyanate that can be used is TRIXENE® Aqua BI 220 from Lanxess Chemical (Germany). In another example, the blocked polyisocyanate is cationic and does not have an acid number. One example of a cationic blocked polyisocyanate that can be used is VESTANAT® EP-DS 1076 (an acetoneoxime blocked polyisocyanate based on isophorone diisocyanate commercially available from Evonik Industries (Germany)). In still another example, the blocked polyisocyanate is an anionic blocked polyisocyanate having an acid number less than about 5 mg KOH/g. In these examples, anionic groups disperse the blocked polyisocyanates but are present in a small number so that the acid number of the anionic blocked polyisocyanate is less than about 5 mg KOH/g. In another example, the blocked polyisocyanate is the anionic blocked polyisocyanate, and the acid number is less than about 3 mg KOH/g. Anionic blocked polyisocyanates having an acid number more than 5 mg KOH/g are not suitable for the example pre-treatment fluids disclosed herein. Some examples of anionic dispersing groups include carboxylates or sulfonates. As used herein, the term “acid number” refers to the mass of potassium hydroxide (KOH) in milligrams that is used to neutralize one (1) gram of a particular substance. For example, with respect to the non-ionic or anionic blocked polyisocyanate, the term “acid number” refers to the mass of potassium hydroxide (KOH) in milligrams that is used to neutralize one gram of the non-ionic or anionic blocked polyisocyanate. To determine this acid number, a known amount of a sample of the non-ionic or anionic blocked polyisocyanate may be dispersed in water and the aqueous dispersion may be titrated with a polyelectrolyte titrant of a known concentration. In this example, a current detector for colloidal charge measurement may be used. An example of a current detector is the Mütek PCD-05 Smart Particle Charge Detector (available from BTG). The current detector measures colloidal substances in an aqueous sample by detecting the streaming potential as the sample is titrated with the polyelectrolyte titrant to the point of zero charge. An example of a suitable polyelectrolyte titrant is poly(diallyldimethylammonium chloride) (i.e., PolyDADMAC). In an example of the inkjet pre-treatment fluid 26, the liquid vehicle includes water and a co-solvent. Examples of suitable co-solvents for the inkjet pre-treatment fluid 26 are water soluble or water miscible co-solvents that may be selected from the group consisting of glycerol, ethoxylated glycerol (also known as glycereth-26, commercially available as LIPONIC® EG-1 (or LEG-1) from Lipo Chemicals), 2-methyl-1,3-propanediol, trimethylolpropane, 1,2-propanediol, dipropylene glycol, and combinations thereof. Other suitable examples of co-solvents include polyhydric alcohols or simple carbohydrates (e.g., trehalose). Further examples of the pre-treatment fluid 26 co-solvent(s) may include alcohols (e.g., diols), ketones, ketoalcohols, ethers (e.g., the cyclic ether tetrahydrofuran (THF), and others, such as thiodiglycol, sulfolane, 2-pyrrolidone, 1-(2-hydroxyethyl)-2-pyrrolidone, 1,3-dimethyl-2-imidazolidinone and caprolactam; glycols such as ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, propylene glycol, dipropylene glycol, tripropylene glycol, trimethylene glycol, butylene glycol, and hexylene glycol; addition polymers of oxyethylene or oxypropylene such as polyethylene glycol, polypropylene glycol and the like; triols such as glycerol (as mentioned above) and 1,2,6-hexanetriol; lower alkyl ethers of polyhydric alcohols, such as ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, diethylene glycol monomethyl, and diethylene glycol monoethyl ether; and lower dialkyl ethers of polyhydric alcohols, such as diethylene glycol dimethyl or diethyl ether. Whether used alone or in combination, the total amount of the co-solvent(s) may be present in the inkjet pre-treatment fluid 26 in an amount ranging from about 5 wt % to about 25 wt % based on a total weight of the inkjet pre-treatment fluid, for use in a thermal inkjet printhead. In another example, the total amount of the co-solvent(s) may be present in the inkjet pre-treatment fluid 26 in an amount ranging from about 10 wt % to about 18 wt % based on a total weight of the inkjet pre-treatment fluid, for use in a thermal inkjet printhead. The co-solvent amount may be increased to increase the viscosity of the pre-treatment fluid for a high viscosity piezoelectric printhead. It is to be understood that water is present in addition to the co-solvent(s) and makes up a balance of the inkjet pre-treatment fluid 26. As such, the weight percentage of the water present in the inkjet pre-treatment fluid 26 will depend, in part, upon the weight percentages of the other components. The water may be purified water or deionized water. An example of the inkjet pre-treatment fluid 26 further comprises an additive selected from the group consisting of a surfactant, a chelating agent, a buffer, a biocide, and combinations thereof. Examples of the inkjet pre-treatment fluid 26 further include a surfactant. The surfactant may be any surfactant that aids in wetting, but that does not deleteriously interact with the blocked polyisocyanate. As such, in an example, the surfactant in the inkjet pre-treatment fluid is selected from the group consisting of a non-ionic surfactant, a cationic surfactant, and a zwitterionic surfactant. The amount of the surfactant that may be present in the inkjet pre-treatment fluid is 2 wt % or less (with the lower limit being above 0) based on the total weight of the inkjet pre-treatment fluid. In some examples, the amount of the surfactant ranges from about 0.1 wt % to about 1 wt % based on the total weight of the inkjet pre-treatment fluid. Examples of suitable non-ionic surfactants include non-ionic fluorosurfactants, non-ionic acetylenic diol surfactants, non-ionic ethoxylated alcohol surfactants, and combinations thereof. Several commercially available non-ionic surfactants that can be used in the formulation of the inkjet pre-treatment fluid include ethoxylated alcohols/secondary alcohol ethoxylates such as those from the TERGITOL® series (e.g., TERGITOL® 15-S-30, TERGITOL® 15-S-9, TERGITOL® 15-S-7), manufactured by Dow Chemical; surfactants from the SURFYNOL® series (e.g., SURFYNOL® SE-F (i.e., a self-emulsifiable wetting agent based on acetylenic diol chemistry), SURFYNOL® 440 and SURFYNOL® 465 (i.e., ethoxylated 2,4,7,9-tetramethyl 5 decyn-4,7-diol)) manufactured by Evonik Industries, and the DYNOL™ series (e.g., DYNOL™ 607 and DYNOL™ 604 ) manufactured by Air Products and Chemicals, Inc.; fluorinated surfactants, such as those from the ZONYL® family (e.g., ZONYL® FSO and ZONYL® FSN surfactants), manufactured by E.I. DuPont de Nemours and Company; alkoxylated surfactants such as TEGO® Wet 510 manufactured from Evonik; fluorinated POLYFOX® non-ionic surfactants (e.g., PF159 non-ionic surfactants), manufactured by Omnova; or combinations thereof. Examples of suitable cationic surfactants that may be used in the inkjet pre-treatment fluid include long chain amines and/or their salts, acrylated diamines, polyamines and/or their salts, quaternary ammonium salts, polyoxyethylenated long-chain amines, quaternized polyoxyethylenated long-chain amines, and/or combinations thereof. Examples of suitable zwitterionic (amphoteric) surfactants that may be used in the inkjet pre-treatment fluid include coco-betaine, alkyl isothionates, N,N-dimethyl-N-dodecylamine oxide, N,N-dimethyl-N-tetradecyl amine oxide (i.e., myristamine oxide), N,N-dimethyl-N-hexadecyl amine oxide, N,N-dimethyl-N-octadecyl amine oxide, N,N-dimethyl-N-(Z-9-octadecenyl)-N-amine oxide, N-dodecyl-N,N-dimethyl glycine, lecithins, phospatidylethanolamine, phosphatidylcholine, and phosphatidylserine. The chelating agent is another example of an additive that may be included in the inkjet pre-treatment fluid 26. When included, the chelating agent is present in an amount greater than 0 wt % actives and less than or equal to 0.5 wt % actives based on the total weight of the pre-treatment fluid. In an example, the chelating agent is present in an amount ranging from about 0.05 wt % actives to about 0.2 wt % actives based on the total weight of the pre-treatment fluid. The wt % actives of the chelating agent accounts for the loading (as a weight percent) of the active chelator/chelating agent present in the pre-treatment fluid, and does not account for the weight of other components of the chelating agent solution (e.g., water) in the pre-treatment fluid. Throughout this disclosure, a weight percentage that is referred to as “wt % actives” refers to the loading of an active component of a dispersion or other formulation that is present in the inkjet pre-treatment fluid or the pigmented inkjet ink. For example, the wt % actives of the chelating agent accounts for the loading (as a weight percent) of the active chelating agent solids present in the inkjet pre-treatment fluid and does not account for the weight of the other components (e.g., water, etc.) of a dispersion (which includes the chelating agent) in the inkjet pre-treatment fluid. The term “wt %,” without the term actives, refers to the loading of a 100% active component that does not include other non-active components therein. In an example, the chelating agent is selected from the group consisting of methylglycinediacetic acid, trisodium salt; 4,5-dihydroxy-1,3-benzenedisulfonic acid disodium salt monohydrate; ethylenediaminetetraacetic acid (EDTA); hexamethylenediamine tetra(methylene phosphonic acid), potassium salt; and combinations thereof. Methylglycinediacetic acid, trisodium salt (Na3MGDA) is commercially available as TRILON® M from BASF Corp. 4,5-dihydroxy-1,3-benzenedisulfonic acid disodium salt monohydrate is commercially available as TIRON™ monohydrate. Hexamethylenediamine tetra(methylene phosphonic acid), potassium salt is commercially available as DEQUEST® 2054 from Italmatch Chemicals. Buffers are another example of an additive that may be included in the inkjet pre-treatment fluid 26. In an example, the total amount of buffer(s) in the inkjet pre-treatment fluid ranges from 0 wt % to about 0.5 wt % (with respect to the weight of pre-treatment fluid). In another example, the total amount of buffer(s) in the ink is about 0.1 wt % (with respect to the weight of pre-treatment fluid). Examples of some suitable buffers include TRIS (tris(hydroxymethyl)aminomethane or Trizma), bis-tris propane, TES (2-[(2-Hydroxy-1,1-bis(hydroxymethyl)ethyl)amino]ethanesulfonic acid), MES (2-ethanesulfonic acid), MOPS (3-(N-morpholino)propanesulfonic acid), HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid), DIPSO (3-(N,N-Bis[2-hydroxyethyl]amino)-2-hydroxypropanesulfonic acid), Tricine (N-[tris(hydroxymethyl)methyl]glycine), HEPPSO (β-Hydroxy-4-(2-hydroxyethyl)-1-piperazinepropanesulfonic acid monohydrate), POPSO (Piperazine-1,4-bis(2-hydroxypropanesulfonic acid) dihydrate), EPPS (4-(2-Hydroxyethyl)-1-piperazinepropanesulfonic acid, 4-(2-Hydroxyethyl)piperazine-1-propanesulfonic acid), TEA (triethanolamine buffer solution), Gly-Gly (Diglycine), bicine (N,N-Bis(2-hydroxyethyl)glycine), HEPBS (N-(2-Hydroxyethyl)piperazine-N′-(4-butanesulfonic acid)), TAPS ([tris(hydroxymethyl)methylamino]propanesulfonic acid), AMPD (2-amino-2-methyl-13-propanediol), TABS (N-tris(Hydroxymethyl)methyl-4-aminobutanesulfonic acid), or the like. Biocides are another example of an additive that may be included in the inkjet pre-treatment fluid 26. In an example, the total amount of biocide(s) in the pre-treatment fluid ranges from about 0 wt % actives to about 0.5 wt % actives (with respect to the weight of the pre-treatment fluid). In another example, the total amount of biocide(s) in the inkjet ink composition is about 0.001 wt % actives to about 0.1 wt % actives (with respect to the weight of the pre-treatment fluid). The wt % actives of the biocide accounts for the loading (as a weight percent) of the active biocidal agent present in the pre-treatment fluid, and does not account for the weight of other components of the biocide (e.g., water) in the pre-treatment fluid. Examples of suitable biocides include the NUOSEPT® (Ashland Inc.), UCARCIDE™ or KORDEK™ or ROCIMA™ (Dow Chemical Co.), PROXEL® (Arch Chemicals) series, ACTICIDE® B 20 and ACTICIDE® M 20 and ACTICIDE® MBL (blends of 2-methyl-4-isothiazolin-3-one (MIT), 1,2-benzisothiazolin-3-one (BIT) and Bronopol) (Thor Chemicals), AXIDE™ (Planet Chemical), NIPACIDE™ (Clariant), blends of 5-chloro-2-methyl-4-isothiazolin-3-one (CIT or CMIT) and MIT under the tradename KATHON™ (Dow Chemical Co.), and combinations thereof. The pH of the inkjet pre-treatment fluid 26 can be less than 7. In some examples, the pH ranges from pH 1 to pH 7, from pH 3 to pH 7, from pH 4.5 to pH 7, etc. In an example, the inkjet pre-treatment fluid 26 consists of the listed components and no additional components (such as water soluble polymers, water repellent agents, etc.). In other examples, the inkjet pre-treatment fluid 26 comprises the listed components, and other components that do not deleteriously affect the jettability of the fluid via a thermal- or piezoelectric inkjet printhead may be added. Examples of the inkjet pre-treatment fluid 26 disclosed herein may be used in a thermal inkjet printer or in a piezoelectric printer to pre-treat a textile substrate. The viscosity of the pre-treatment fluid may be adjusted for the type of printhead that is to be used, and the viscosity may be adjusted by adjusting the co-solvent level and/or adding a viscosity modifier. When used in a thermal inkjet printer, the viscosity of the pre-treatment fluid may be modified to range from about 1 centipoise (cP) to about 5 cP (at 20° C. to 25° C.), and when used in a piezoelectric printer, the viscosity of the pre-treatment fluid may be modified to range from about 2 cP to about 16 cP (at 20° C. to 25° C.), depending on the viscosity of the printhead that is being used (e.g., low viscosity printheads, medium viscosity printheads, or high viscosity printheads). Textile Fabrics In an example of printing method 100 (and for use in the system 30), the textile fabric 33 is selected from the group consisting of polyester fabrics, polyester blend fabrics, cotton fabrics, cotton blend fabrics, nylon fabrics, nylon blend fabrics, silk fabrics, silk blend fabrics, and combinations thereof. In a further example, textile fabric 33 is selected from the group consisting of cotton fabrics and cotton blend fabrics. It is to be understood that organic textile fabrics and/or inorganic textile fabrics may be used for the textile fabric 33. Some types of fabrics that can be used include various fabrics of natural and/or synthetic fibers. It is to be understood that the polyester fabrics may be a polyester coated surface. The polyester blend fabrics may be blends of polyester and other materials (e.g., cotton, linen, etc.). In another example, the textile fabric 33 may be selected from nylons (polyamides) or other synthetic fabrics. Example natural fiber fabrics that can be used include treated or untreated natural fabric textile substrates, e.g., wool, cotton, silk, linen, jute, flax, hemp, rayon fibers, thermoplastic aliphatic polymeric fibers derived from renewable resources (e.g. cornstarch, tapioca products, sugarcanes), etc. Example synthetic fibers used in the textile fabric/substrate can include polymeric fibers such as nylon fibers, polyvinyl chloride (PVC) fibers, PVC-free fibers made of polyester, polyamide, polyimide, polyacrylic, polypropylene, polyethylene, polyurethane, polystyrene, polyaramid (e.g., Kevlar®) polytetrafluoroethylene (Teflon®) (both trademarks of E.I. du Pont de Nemours and Company, Delaware), fiberglass, polytrimethylene, polycarbonate, polyethylene terephthalate, polyester terephthalate, polybutylene terephthalate, or a combination thereof. In some examples, the fiber can be a modified fiber from the above-listed polymers. The term “modified fiber” refers to one or both of the polymeric fiber and the fabric as a whole having undergone a chemical or physical process such as, but not limited to, copolymerization with monomers of other polymers, a chemical grafting reaction to contact a chemical functional group with one or both the polymeric fiber and a surface of the fabric, a plasma treatment, a solvent treatment, acid etching, or a biological treatment, an enzyme treatment, or antimicrobial treatment to prevent biological degradation. It is to be understood that the terms “textile fabric” or “fabric substrate” do not include materials commonly known as any kind of paper (even though paper can include multiple types of natural and synthetic fibers or mixtures of both types of fibers). Fabric substrates can include textiles in filament form, textiles in the form of fabric material, or textiles in the form of fabric that has been crafted into finished articles (e.g., clothing, blankets, tablecloths, napkins, towels, bedding material, curtains, carpet, handbags, shoes, banners, signs, flags, etc.). In some examples, the fabric substrate can have a woven, knitted, non-woven, or tufted fabric structure. In one example, the fabric substrate can be a woven fabric where warp yarns and weft yarns can be mutually positioned at an angle of about 90°. This woven fabric can include fabric with a plain weave structure, fabric with twill weave structure where the twill weave produces diagonal lines on a face of the fabric, or a satin weave. In another example, the fabric substrate can be a knitted fabric with a loop structure. The loop structure can be a warp-knit fabric, a weft-knit fabric, or a combination thereof. A warp-knit fabric refers to every loop in a fabric structure that can be formed from a separate yarn mainly introduced in a longitudinal fabric direction. A weft-knit fabric refers to loops of one row of fabric that can be formed from the same yarn. In a further example, the fabric substrate can be a non-woven fabric. For example, the non-woven fabric can be a flexible fabric that can include a plurality of fibers or filaments that are one or both bonded together and interlocked together by a chemical treatment process (e.g., a solvent treatment), a mechanical treatment process (e.g., embossing), a thermal treatment process, or a combination of multiple processes. Pigmented Inkjet Inks The inkjet pre-treatment fluid may be directly applied to a textile fabric prior to the application of a pigmented inkjet ink. Examples of suitable pigmented inkjet inks that may be used with the inkjet pre-treatment fluid will now be described. Any suitable pigmented inkjet ink may be used in the examples disclosed herein. The inkjet formulation may include a pigment dispersion, a polymeric binder (i.e., binder resin), and a liquid vehicle. Pigment Dispersion The pigment dispersion may include a pigment and a separate dispersant, or may include a self-dispersed pigment. Whether separately dispersed or self-dispersed, the pigment can be any of a number of primary or secondary colors, or black or white. As specific examples, the pigment may be any color, including, as examples, a cyan pigment, a magenta pigment, a yellow pigment, a black pigment, a violet pigment, a green pigment, a brown pigment, an orange pigment, a purple pigment, a white pigment, or combinations thereof.

Pigment Green 4, C.I. Pigment Green 7, C.I. Pigment Green 8, C.I. Pigment Green 10, C.I. Pigment Green 36, and C.I. Pigment Green 45. Examples of brown organic pigments include C.I. Pigment Brown 1, C.I. Pigment Brown 5, C.I. Pigment Brown 22, C.I. Pigment Brown 23, C.I. Pigment Brown 25, C.I. Pigment Brown 41, and C.I. Pigment Brown 42. Some examples of orange organic pigments include C.I. Pigment Orange 1, C.I. Pigment Orange 2, C.I. Pigment Orange 5, C.I. Pigment Orange 7, C.I. Pigment Orange 13, C.I. Pigment Orange 15, C.I. Pigment Orange 16, C.I. Pigment Orange 17, C.I. Pigment Orange 19, C.I. Pigment Orange 24, C.I. Pigment Orange 34, C.I. Pigment Orange 36, C.I. Pigment Orange 38, C.I. Pigment Orange 40, C.I. Pigment Orange 43, C.I. Pigment Orange 64, C.I. Pigment Orange 66, C.I. Pigment Orange 71, and C.I. Pigment Orange 73. The average particle size of the pigments may range anywhere from about 20 nm to about 200 nm. In an example, the average particle size ranges from about 80 nm to about 150 nm. Any of the pigments mentioned herein can be dispersed by a separate dispersant, such as a styrene (meth)acrylate dispersant, or another dispersant suitable for keeping the pigment suspended in the liquid vehicle. For example, the dispersant can be any dispersing (meth)acrylate polymer, or other type of polymer, such as maleic polymer or a dispersant with aromatic groups and a poly(ethylene oxide) chain. In one example, (meth)acrylate polymer can be a styrene-acrylic type dispersant polymer, as it can promote Tr-stacking between the aromatic ring of the dispersant and various types of pigments, such as copper phthalocyanine pigments, for example. In one example, the styrene-acrylic dispersant can have a weight average molecular weight ranging from about 4,000 Mw to about 30,000 Mw. In another example, the styrene-acrylic dispersant can have a weight average molecular weight ranging from about 8,000 Mw to about 28,000 Mw, from about 12,000 Mw to about 25,000 Mw, from about 15,000 Mw to about 25,000 Mw, from about 15,000 Mw to about 20,000 Mw, or about 17,000 Mw. Regarding the acid number, the styrene-acrylic dispersant can have an acid 30 number from 100 to 350, from 120 to 350, from 150 to 300, from 180 to 250, or about 214, for example. Example commercially available styrene-acrylic dispersants can include JONCRYL® 671, JONCRYL® 71, JONCRYL® 96, JONCRYL® 680, JONCRYL® 683, JONCRYL® 678, JONCRYL® 690, JONCRYL® 296, JONCRYL® 696 or JONCRYL® ECO 675 (all available from BASF Corp., Germany) The term “(meth)acrylate” or “(meth)acrylic acid” or the like refers to monomers, copolymerized monomers, etc., that can either be acrylate or methacrylate (or a combination of both), or acrylic acid or methacrylic acid (or a combination of both). Also, in some examples, the terms “(meth)acrylate” and “(meth)acrylic acid” can be used interchangeably, as acrylates and methacrylates are salts and esters of acrylic acid and methacrylic acid, respectively. Furthermore, mention of one compound over another can be a function of pH. Furthermore, even if the monomer used to form the polymer was in the form of a (meth)acrylic acid during preparation, pH modifications during preparation or subsequently when added to an ink composition can impact the nature of the moiety as well (acid form vs. salt or ester form). Thus, a monomer or a moiety of a polymer described as (meth)acrylic acid or as (meth)acrylate should not be read so rigidly as to not consider relative pH levels, ester chemistry, and other general organic chemistry concepts. The following are some example pigment and separate dispersant combinations: a carbon black pigment with a styrene acrylic dispersant; PB 15:3 (cyan pigment) with a styrene acrylic dispersant; PR122 (magenta) or a co-crystal of PR122 and PV19 (magenta) with a styrene acrylic dispersant; or PY74 (yellow) or PY155 (yellow) with a styrene acrylic dispersant. In an example, the pigment is present in the inkjet ink in an amount ranging from about 0.5 wt % to about 6 wt % of the total weight of the inkjet ink. In another example, the pigment is present in the thermal inkjet ink in an amount ranging from about 1 wt % to about 6 wt % of the total weight of the inkjet ink. When the separate dispersant is used, the separate dispersant may be present in an amount ranging from about 0.05 wt % to about 6 wt % of the total weight of the inkjet ink. In some examples, the ratio of pigment to separate dispersant may range from 0.1 (1:10) to 1 (1:1). Self-Dispersed Pigments In other examples, the inkjet ink a self-dispersed pigment including a pigment and an organic group attached thereto. Any of the pigments set forth herein may be used, such as carbon, phthalocyanine, quinacridone, azo, or any other type of organic pigment, as long as at least one organic group that is capable of dispersing the pigment is attached to the pigment. The organic group that is attached to the pigment includes at least one aromatic group, an alkyl (e.g., C1 to C20), and an ionic or ionizable group. The aromatic group may be an unsaturated cyclic hydrocarbon containing one or more rings and may be substituted or unsubstituted, for example with alkyl groups. Aromatic groups include aryl groups (for example, phenyl, naphthyl, anthracenyl, and the like) and heteroaryl groups (for example, imidazolyl, pyrazolyl, pyridinyl, thienyl, thiazolyl, furyl, triazinyl, indolyl, and the like). The alkyl may be branched or unbranched, substituted or unsubstituted. The ionic or ionizable group may be at least one phosphorus-containing group, at least one sulfur-containing group, or at least one carboxylic acid group. In an example, the at least one phosphorus-containing group has at least one P—O bond or P═O bond, such as at least one phosphonic acid group, at least one phosphinic acid group, at least one phosphinous acid group, at least one phosphite group, at least one phosphate, diphosphate, triphosphate, or pyrophosphate groups, partial esters thereof, or salts thereof. By “partial ester thereof”, it is meant that the phosphorus-containing group may be a partial phosphonic acid ester group having the formula —PO3RH, or a salt thereof, wherein R is an aryl, alkaryl, aralkyl, or alkyl group. By “salts thereof”, it is meant that the phosphorus-containing group may be in a partially or fully ionized form having a cationic counterion. When the organic group includes at least two phosphonic acid groups or salts thereof, either or both of the phosphonic acid groups may be a partial phosphonic ester group. Also, one of the phosphonic acid groups may be a phosphonic acid ester having the formula —PO3R2, while the other phosphonic acid group may be a partial phosphonic ester group, a phosphonic acid group, or a salt thereof. In some instances, it may be desirable that at least one of the phosphonic acid groups is either a phosphonic acid, a partial ester thereof, or salts thereof. When the organic group includes at least two phosphonic acid groups, either or both of the phosphonic acid groups may be in either a partially or fully ionized form. In these examples, either or both may of the phosphonic acid groups have the formula —PO3H2, —PO3H−M+ (monobasic salt), or —PO3−2 M+2 (dibasic salt), wherein M+ is a cation such as Na+, K+, Li+, or NR4+, wherein R, which can be the same or different, represents hydrogen or an organic group such as a substituted or unsubstituted aryl and/or alkyl group. As other examples, the organic group may include at least one geminal bisphosphonic acid group, partial esters thereof, or salts thereof. By “geminal”, it is meant that the at least two phosphonic acid groups, partial esters thereof, or salts thereof are directly bonded to the same carbon atom. Such a group may also be referred to as a 1,1-diphosphonic acid group, partial ester thereof, or salt thereof. An example of a geminal bisphosphonic acid group may have the formula —CQ(PO3H2)2, or may be partial esters thereof or salts thereof. Q is bonded to the geminal position and may be H, R, OR, SR, or NR2 wherein R, which can be the same or different when multiple are present, is selected from H, a C1-C18 saturated or unsaturated, branched or unbranched alkyl group, a C1-C18 saturated or unsaturated, branched or unbranched acyl group, an aralkyl group, an alkaryl group, or an aryl group. For examples, Q may be H, R, OR, SR, or NR2, wherein R, which can be the same or different when multiple are present, is selected from H, a C1-C6 alkyl group, or an aryl group. As specific examples, Q is H, OH, or NH2. Another example of a geminal bisphosphonic acid group may have the formula —(CH2)nCQ(PO3H2)2, or may be partial esters thereof or salts thereof, wherein Q is as described above and n is 0 to 9, such as 1 to 9. In some specific examples, n is 0 to 3, such as 1 to 3, or n is either 0 or 1. Still another example of a geminal bisphosphonic acid group may have the formula
