The Science of Tuning Color on Toner-Based Copiers/Printers

This Technical Innovation paper is a summary of experience acquired while tuning many production printers and copiers installed at customer sites in-order to optimize color accuracy, consistency and image quality. The emphasis is on tuning device, profile and calibration properties, and does not simply present profile building or color validation techniques. The majority of this experience has been gained while tuning Ricoh printers and copiers, but concepts apply to other toner-based devices. Examples and processes are as used on EFI Fiery RIPS, but practices apply to other RIPs with minor change. This document identifies needed processes and components without full operational details; relevant vendor service documentation should be consulted.
