Image Processing Method Incorporating Decompression

摘要

A method is provided for image processing a page to be printed. The method includes the step of respectively decompressing a bi-level black layer and a contone layer of a page to be printed. The decompressed contone layer is halftoned to form a bi-level cyan, yellow, magenta, and black (CYMK) layer. The method further includes the step of 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.
