Abstract: A raster image processing system and method accepts a digital page description as a series of page elements (text, graphics, images, etc.) and creates output video-ready (“flattened”) raster without allocating large amounts of raster memory (arrays of pixels) and without creating a display list of all page elements. This technique improves performance (greater speed with fewer resources consumed) in the typical output process: rendering, image processing, compression, and transmission. The method records each page element in memory in a manner that largely retains the inherent compression of the element description, and fully retains the positional relationships with its neighboring elements. Where an incoming page element overlaps an existing one, the intersections are calculated on the fly, and elements underneath are immediately split, merged, shrunken, or deleted. Each incoming page element is immediately processed and recorded as described above, and then discarded.

Abstract: A number of different print jobs having different print quantities can be combined into a single job that results in reduced bindery costs. An imposition is produced with the print patterns for the different print jobs in different print positions. Jobs with larger print quantities can occupy a greater number of print positions. The allocation of print positions among the different print jobs can be based on quantity ratios. A print job having twice the quantity of another should occupy twice the number of print positions. Proper allocation of print positions results in maximizing the number of sheets that can be printed with a single imposition. Maximizing the number of identically printed sheets results in reduced bindery costs.

Further, the elements may be outlined. These improvements make elements in the document more distinguishable after its conversion to a monochrome format. The described color optimization and outlining may have wide applicability in the Internet Fax technology.
