Abstract
Printing multi-color images on non-vinyl plastic identification documents in identification document printing systems. A non-linear pixel density adjustment curve is used to adjust the pixel density data of a multi-color image to be printed which adjusts the power applied to the thermal print head. The use of a non-linear pixel density adjustment curve to adjust the pixel density data improves the quality of the resulting multi-color printed image, reduces mass transfer of the dye donor layer, and reduces breaking of the carrier film of the print ribbon.
