Abstract: What is provided herein is a novel system and method for estimating the amount of color in a document to be printed, with the capability to handle composite black, in those environments without access to all the original four color planes simultaneously. In one embodiment, input CMYK values are pre-adjusted via a look-up table to take into account the neutral balance characteristics. The planes are then scaled and quantized so that all four planes become available simultaneously. The difference among the quantized CMYK color values is compared against a threshold that is input level dependent. A pixel is classified into one of several color categories such as, for example, true neutral, fuzzy neutral, true color or fuzzy color. A color billing strategy can then be automatically determined based on the amount of color content. The method advantageously provides flexibility to support multi-tier billing in systems with various marking technologies.
