Abstract

A method for printing an image with improved printing quality using liquid ink includes using a pump to pump ink to a print head for printing rows of the image onto a moving printing substrate. A respective value correlated with the amount of ink required to print the rows is calculated for a plurality of individual rows or a plurality of grouped rows of the image. The pump receives a preemptive control signal based on the calculated values.
