Abstract: A printing system includes one or more lineheads that jet ink onto a first side of a print media. At least one roller supports a second side of the print media as the print media is transported through the printing system. A roller deformation adjustment mechanism abuts at least one roller and is configured to apply a force to the roller to deform the roller. The deformation of the roller compensates for web skew by changing the relative timing of ink flight times from the linehead to the first side of the print media. The linehead can be disposed on a movable support. The printing system can also include one or more linehead skew adjustment mechanisms configured to move the movable support to adjust a skew of the linehead.

Abstract: A method for aligning multi-channel digital image data for a digital printer having a plurality at least one printhead is described. One or more spatial adjustment parameters are determined for each of the printheads. The spatial adjustment parameters can be determined by comparing locations of test pattern indicia in a printed test pattern to predefined reference indicia locations. Digital image data for the non-reference printheads is modified by designating an input pixel neighborhood within which an image pixel should be inserted or deleted, comparing the image pixels in the input pixel neighborhood to a plurality of predefined pixel patterns to identify a matching pixel pattern; and determining a modified pixel neighborhood responsive to the matching pixel pattern.
