Patent ID: 7673965

Claim:
A printer comprising: a conveyor defining an X direction (W) and a Y direction (L) perpendicular to the X direction, the conveyor configured to receive a substrate of maximum width W 2 in the X direction and to move the substrate linearly in the Y direction; a first array of multiple inkjet print heads distributed along the X direction and substantially spanning the width W 2 ; a second array of multiple inkjet print heads distributed along the X direction and substantially spanning the width W 2 ; where the print heads have a prescribed native resolution and a prescribed dot pitch; supports spanning the conveyor in the X direction, the supports being selectively shiftable in at least the X direction independently of each other by actuators and position detectors coupled to the supports, each support having a different one of the arrays mounted thereto; where the supports are shifted to position the first and second arrays with a relative offset in the X direction by an amount less than the prescribed dot pitch in order to print in greater resolution than said native resolution.
