Abstract
A system for improving the uniformity of ink droplets delivered from a plurality of droplet sources on a printhead is described. The system includes a cooling system that compensates for nonuniform heating effects in a printhead which results in nonuniform temperatures. The distribution of the cooling system, and the effectiveness of the cooling system is set to maintain an approximately uniform ink temperature across the printhead.
