Abstract
Provided is a direct thermal media containing a regular repeating pattern of color-forming thermally-imageable stripes printed parallel to the print head element line and a system for using such direct thermal media in color direct thermal printers including an optical registration system optimized for use with this media and an image processing unit that monitors the position of the stripe pattern relative to the print head and synchronizes the start of the printing process. This direct thermal media together with the optical registration system and image processing unit comprise an operative system in that the design of the thermal media, the optical registration system and image processing unit used to control printing are optimized for use with each other. This system may be utilized, for example, in color thermal printers for documents, receipts, tags, tickets or labels.
