ABSTRACT:
Forced compression halftone processes and forced compression techniques may be used to forcibly compress page raster images passed between a Digital Front End (DFE) processor and a Continuous Feed (CF) printer within a CF printing system. If a DFE processor determines that a compressed image size exceeds a static or dynamically predetermined threshold, the DFE processor may re-render the image using a “forced compression” halftone process, such as 2-to-1 forced compression, 4-to-1 forced compression, reduced resolution, etc. Once the page raster image has been re-rendered, the DFE processor may use a forced compression technique, which is complimentary to the applied “forced compression” halftone process to re-compress the page raster image. The approach allows page raster images to be compressed to meet interface bandwidth constraints associated with the physical interface between the DFE processor and CF print engine, thereby allowing otherwise unprintable jobs to be printed with reasonable quality.
