Abstract:
1. A method of processing images in a digital printer, comprising: (a) receiving an electronic image file, the electronic image file including at least one object representing a contone image and at least one object representing a non-contone image; (b) processing the contone image object to generate an edge tagged encoded binary image data stream; (c) processing the non-contone image object to generate an encoded binary data stream; (d) applying a first binary to contone conversion process to the encoded binary data stream to generate a first contone image stream; and (e) applying a second binary to contone conversion process to the edge tagged encoded binary image data stream to generate a second contone image stream; and (f) combining the first contone image stream and the second contone image stream to form a single contone page image stream for rendering by a digital printer.
