Abstract
A method and means for compensating for lateral registration errors in printing machines of the type having a plurality of image processing stations for forming a composite image on an imageable surface which moves relative to the stations. The invention includes monitoring means for determining the angular displacement of the surface from a reference in the process direction to thereby determine the lateral registration error at each of the image processing stations. Actuating means are provided to move the image processing stations laterally relative to the surface to provide lateral registration of the images formed on the surface. The invention may also include means for compensating for process direction registration errors including monitoring means for determining the angular displacement of the surface from a reference in lateral direction at each of the image processing stations and providing means to rotate the image processing stations relative to the surface to provide process direction registration of the images formed on the surface.
