 the wine is bottled. Printing of natural cork stoppers is typically done using a rotary letter press or rotary letter flex printing system which utilizes a reverse reading hard or soft printing plate which has ink placed on the raised surface. The raised surface of the plate then makes contact with the natural cork, thus transferring the appropriate image. This printing process is typically limited to single color printing.
Printing machines used for printing indicia on natural cork stoppers have been found to be ineffective when used with synthetic cork stoppers. The synthetic stoppers are not as absorbent as natural cork and the printing on such corks, regardless of transfer method, require a forced drying of the printed ink. Additionally, the synthetic corks have a lower coefficient of friction at their and require a surface treatment, which oxidizes the surface allowing the printing ink to "flow out" when applied to the surface.
Therefore it would be advantageous to have a printing machine capable of imprinting synthetic cork stoppers with forced surface pretreatment and forced ink drying. It would also be advantageous to have a printing machine capable of printing synthetic cork stoppers that more securely holds the synthetic stoppers to reduce the likelihood of machine jams. It would also be advantageous to have a printing machine capable of printing synthetic cork stoppers which is more compact than previously known synthetic cork printing machines. 1.
