ABSTRACT:
An apparatus that monitors the quality of copies reproduced by a printing machine. A signal of an image to be reproduced by the printing machine is transmitted to an electronic subsystem. The electronic subsystem converts the signal to a reference bitmap and transmits the reference bitmap to a raster output scanner in the printing machine. The printing machine reproduces the image on a copy sheet. The image reproduced on the copy sheet is scanned by a raster input scanner and a scanned bitmap generated. A comparison is made between the scanned bitmap and the reference bitmap to determine if the image reproduced on the copy sheet is at an acceptable quality level.
