System and method for ejecting adjustable amounts of ink

摘要

A method for controlling an inkjet printing system including calculating a pigment concentration of ink ejected by the inkjet printhead relative to an initial pigment concentration of the ink based on a determined height of ink in an ink reservoir and a determined period of time since a last printhead activation. A firing pattern for the inkjet printhead is determined based on the determined height, the determined period of time and the calculated relative pigment concentration to account for settling of ink stored in the ink reservoir.
