Abstract
Systems and methods of reusing binary bitmaps for images appearing multiple times in a print job. In one embodiment, a system stores a binary bitmap for an image that appears in a print job. The system determines an offset of the binary bitmap into a sheetside, and calculates position values for the binary bitmap based on the offset of the binary bitmap. The system identifies a next appearance of the image in the print job, determines an offset of the image into a sheetside for the next appearance, and calculates position values for the next appearance of the image based on the offset of the image. The system determines if the position values for the image correspond with the position values for the binary bitmap, and verifies that the binary bitmap is reusable for the next appearance of the image if the position values correspond.
