Abstract
A method and system for printing of gray scale images utilizes raster image data. A page is divided into tiles in a two dimensional grid. Tiles are checked for the presence of dither cells for generating gray scale values. Tiles without dither cells are compressed for transmission while tiles having dither cells are not compressed.
