摘要
Systems and methods described herein provide for an efficient method for print job compression. In some embodiments, threshold halftone lookup tables directed to specific object types are used to compare pixel data for specific detected objects. Pixel data for such specified objects may be encoded using the appropriate object-specific threshold halftone lookup table into one of two multi-bit values, which serve to increase the frequency of repetitive or redundant encoded data and permit efficient compression by algorithms that exploit data repetition and/or redundancy. The methods described herein are applicable to a variety of printers, including raster and PDL printers.
