| 1. A method for image processing page data representing a page to be printed, the method comprising the steps of:
respectively decompressing a bi-level black layer and a contone layer of the page data;
halftoning the decompressed contone layer to form a bi-level cyan, yellow, magenta, and black (CYMK) layer;
compositing the decompressed bi-level black layer over the bi-level CYMK layer to form a bi-level CYMK image of the page to
be printed; and
carrying out processing operations for printing the CMYK image.
