The Ink Capabilities of UV Printing
How do the accommodations of UV printing compare to inkjet printing?
UV printers can accommodate not only the standard CMYK inks, but also white ink, clear gloss, and sometimes even a primer ink for improved adhesion.
Normally, when a file is sent to print on a standard inkjet printer, white areas of the design are interpreted as “transparent” and are not printed. However, with UV printing, white areas can actually be assigned to print in white ink, and inks like clear gloss can be applied by the addition of alpha channels within your graphics file so that they are interpreted as “spot colors” by the printer.
