Paper Abstract

Gamut mapping is a critical process in the output color management of a printer. In systems consisting of two or more marking engines, these engines could in general have different output color gamuts. In special cases these gamuts can be drastically different. When applying gamut mapping to a multi-engine printing system, which gamut to use is not obvious. In the default case, i.e., if the multi-engine system is treated as a single engine with a single gamut, poor image quality could result. In this paper, we propose gamut mapping strategies for multiple engine printing, which depend on the relative importance of "color rendition" and "page-to-page color consistency" within a given document. In particular, we propose a content-based gamut mapping, wherein the trade-offs between color rendition and page-to-page color consistency can be automatically and dynamically made by segmenting the document and applying gamut mapping according to the needs of the segmented components.
