Abstract: Color registration errors are corrected for print jobs including periodic image content. Pixels values for a set of document pages are analyzed to identify the presence a periodic pattern of ink coverage having a repeat period. A first subset of document pages are printed and the resulting color registration errors are measured and analyzed to determine a periodic pattern of color registration errors. A repeating pattern of color registration correction values are determined corresponding to the periodic pattern of color registration errors. A second subset of the document pages is printed using the determined repeating pattern of color registration correction values.

Abstract: A method for correcting image plane registration errors for a multi-channel printing system that prints documents of a particular document-type classification having a variable number of pages. An image plane registration error database stores image plane registration error information characterizing image plane registration errors as a function of page number for each of a plurality of different page-count classifications. A page-count classification is determined for a document to be printed, and image plane registration correction values are determined for each page based on the stored image plane registration error information associated with the determined page-count classification, wherein the image plane registration correction values for each page are determined based on the stored image plane registration error information for the corresponding page number. The image data for each document page of the document is then printed responsive to the corresponding image plane registration correction values.

Abstract: A print engine synchronization system apparatus enables the movement of a first print engine dielectric support member (DSM) having one or more image frames as well as the movement of a second print engine DSM having one or more image frames by monitoring a first frame signal from the moving first print engine DSM and a second frame signal from the moving second print engine DSM. An offset is determined for each of corresponding pairs of frames from the one or more image frames of the first and second print engine DSM and the determined offset for each corresponding pair of frames is compared to a target offset to maintain synchronization between the first and second print engines on a frame by frame basis by adjusting a second print engine DSM velocity based on the comparison of the determined offset and the target offset.
