Method and apparatus for compensating for raster position errors in output scanners

摘要

The present invention is a method and apparatus for compensating for position error inherent in a raster output scanning printing system by adjusting (64) the intensity of image exposure to effect a correction in the output image. The invention is particularly well suited to compensate for position errors arising from a plurality of sources by first summing (62) the errors and then applying a single compensating adjustment to the intensity of individual scan rasters based upon the position error thereof.
