Abstract
A printing system using multiple printheads maintains color consistency between the printheads by printing a first color patch (102) with a first color with a plurality of printheads (30) at a first pressure and with a first pixel fill coverage. A second color patch (104) is printed with the first color with the plurality of printheads at a second pressure with the first pixel fill coverage. The print density of the first patch and the second patch is measured for each of the plurality of printheads and the print density for each of the plurality of printheads is compared. A pressure for each of the plurality of printheads is adjusted to compensate for differences in density between the first patch and the second patch for each of the printheads.
