Abstract
A device and method for converting a multi-bit full color input image into a highlight color format for output on a highlight color image output terminal. The method and device analyze each pixel block on a block-by-block basis and assign each block to one of highlight color and non-highlight color. Each color is processed as a separate image file and can be combined after processing into a mixed raster file for output. At least the highlight color image portion can be converted to a single-bit file to reduce processing constraints.
