Abstract: Reducing print quality defects can include printing a pattern with an offset printing device having a binary ink developer roller, determining a variation for a hue shift of the printed pattern; and varying gain in a feedback loop of a servo motor coupled to the binary ink developer roller to reduce the variation.
