System and method for using pulse or trickle warming to control neutral color balance on a print media

Abstract

The present invention includes an embodiment for optimizing the temperature operating range for a thermal inkjet printhead using ink over large print swaths. In general, this embodiment includes receiving the temperature of a digital temperature sensor (DTS) before printing begins, comparing this temperature with the set point for printing, initiating heating elements if the temperature is below the printing threshold, and turning off those heating elements when the threshold temperature of the die has been reached. The method and process minimizes thermal excursions, either above or below the set point for the production of ink droplets, and maintains an approximate isothermal environment for operation
