characteristics to the Palatino Sans, such as asymmetrical A, K, N, W, X, Y, w. Palatino Arabic It is a family designed by Lebanese designer Nadine Chahine and Hermann Zapf. The design is based on the Al-Ahram typeface designed by Zapf in 1956 but reworked and modified to fit the Palatino nova family. The design is Naskh in style but with a strong influence of Thuluth style. This family only comes in 1 font, with the Arabic characters based on Palatino nova Regular. It supports basic Latin, Arabic, Persian, and Urdu scripts. Chahine also created a version of Zapf's Zapfino. Palatino eText (2013) It is a family designed by Toshi Omagari of Monotype Imaging, optimised for on-screen use. It includes a larger x-height and wider spacing. It is the standard four-font family, with bolds and italics. Palatino clones As one of the most iconic typefaces of the twentieth century, derivative designs based on Palatino were rapidly developed, taking advantage of the lack of practical copyright and the easy copying possible in the phototypesetting font market of the 1960s and 70s onwards. Many of these are almost indistinguishable from Palatino, and some even had Zapf's involvement as a consultant. Palazzo Original Softmaker's clone of Palatino, Palazzo Original, is unique for being based on the original metal type of Palatino: as a result, it contains many design features not seen in the digital versions of Palatino endorsed by Zapf and most clones. These include a 'p' and 'q' without foot serif and no serif on the centre stroke of the 'E' and 'F', as well as a slightly more delicate design with a lower x-height. It has also been released as Marathon Serial without italics. PostScript clones Most modern Palatino clones are set to match the spacing and design of the PostScript version of Palatino that was a standard font in early digital publishing. In the Bitstream font collection, the Palatino equivalent is called "Zapf Calligraphic". URW++ sells its version as "URW Palladio L". A version of this font was later released by URW under a free and open-source licence as part of the Ghostscript project to develop an open-source alternative to PostScript. As a result, it (or a derivative) is used by much open-source software such as R as a system font. Palladio, however, lacks the subtle stroke modulation and rounded corners which can be found for example in Palatino Linotype.
