Abstract

Apparatus for color printing on a re-inkable belt, the re-inkable belt being moveable along an endless path and trained about a transport roller and including an ink transfer layer where an ink can be transferred to a moveable receiver and the moveable receiver moves into ink transfer relationship with the re-inkable belt at a nip position for transferring ink imagewise from the re-inkable belt to the receiver. The depleted ink is replenished and the re-inkable belt is arranged so that ink will be diffused into the ink transfer surface, and tension is adjustedly applied at two spaced locations to the transport roller and including two spaced steering actuators which, when actuated, apply tension to opposite positions on the transport roller, a sensor for determining the position of the re-inkable belt, and a computer coupled to the sensor for selectively actuating the steering actuators so as to apply tension to the transport roller which compensates for lateral distortion of the re-inkable belt.
