Abstract

An image based correction system compensates for the image quality artifacts induced by thermal ghosting. With thermal ghosting directly tied to previous image content, a feed forward control system predicts the thermal ghosting artifact based on the images previous printed and generates an open loop, 2-D correction to the gray-level image that mitigates the undesirable ghosting artifacts. For example, the correction system compensates for the thermal ghosting by making the current digital image 'lighter' in areas that will be imaged onto warmer blanket regions, thereby cancelling out TRC differences between different temperature regions.
