Thermal transfer print
General information
Thermal transfer print carries a thin dye or resin color layer to card surface, which is later overlaminated for weather and mechanical protection. There is monochrome and full-color thermal transfer print available. With thermal transfer print technique there is no limitation to printed image – any computer-prepared image can be carried to card, including special fonts, bar-codes and photographs. Full-color thermal transfer print enables printing of cardholders photograph on card (used at pass-control, permanent passenger tickets, certificate, license, etc. cards). It’s also possible to print “invisible bar-codes” – ie. bar-codes, invisible to human eyes, but readable with special devices.
