METHODS AND SYSTEMS FOR PROCESSING DOCUMENTS USING MULTIPLE HALFTONE SCREENING TECHNIQUES

摘要

A method of processing a document for printing includes receiving a document; for at least one of the plurality of regions, determining a drop size for that region and determining whether the drop size for printing the region meets a threshold criterion and, if so, processing the region using a tile-based screen for halftoning and, if not, processing the region using an error diffusion screen for halftoning; and printing the processed regions. Another method includes additionally considering coverage level to determine whether to use a tile-based screen or error diffusion screen. Yet another method includes determining whether the region is within a threshold range of a drop step change.
