Abstract: In one aspect of the invention there is disclosed a multicolor thermal imaging system wherein different heating elements on a thermal print head can print on different color-forming layers of a multicolor thermal imaging member in a single pass. The line-printing time is divided into segments, each of which is divided into a plurality of subintervals. All of the pulses within the segments have the same energy. In one embodiment, every pulse has the same amplitude and duration. Different colors are selected for printing during the different segments by varying the fraction of subintervals that contain pulses. This technique allows multiple colors to be printed using a thermal print head with a single strobe signal line. Pulsing patterns may be chosen to reduce the coincidence of pulses provided to multiple print head elements, thereby reducing the peak power requirements of the print head.

Abstract: A thermal printing head having a two-dimensional array of resistive heating elements, and a method of printing using such a thermal printing head. The resistive heating elements in different rows of such elements may differ in dimensions, resistance, or other physical properties. The thermal printing head may be used to address a direct thermal medium containing more than one color-forming composition, in which different color-forming compositions produce different colors when heated.
