<p>A method and means for compensating for lateral registration errors in printing machines of the type having a plurality of image processing stations (A,B,C) for forming a composite image on an imageable surface (13) which moves relative to the stations. Monitoring means (146,156) are provided for determining the angular displacement DIAMETER of the surface from a reference (302) in the process direction to thereby determine the lateral registration error at each of the image processing stations. Actuating means (138) are provided to move the image processing stations laterally relative to the surface to provide lateral registration of the images formed on the surface. Means may also be provided for compensating for process direction registration errors including means (139) to rotate the image processing stations relative to the surface to provide process direction registration of the images formed on the surface. <IMAGE> <IMAGE></p> |
