With today's time to market pressure, there is a need for remote contract proofing. Remote contract proofing is remote printing with a twist, Certification. Certification is the quantification of the actual color of the ink on paper. We discuss the need for color consistency, accurate and repeatable measurement. The issues and results surrounding accuracy and repeatability of various measurement instruments and proofing devices are explained. Alternative issues of what colors to measure, how to integrate the measurement into the workflow, and how to represent variances are explained. Several examples are given, with cost-benefit analysis where practical. Outstanding issues of color science are discussed. Measurement and the effect on overall system performance are covered in depth.There is a great need for timely communication of color quality to various team/project members. The solutions involve both the obvious digital network for transporting the image (fat pipe) and the network and database transporting and storing the meta-data gathered at image transport, image proof, and image certification (thin pipe). Database issues are discussed along with various choices for implementation along with the relative costs. Network reliability issues are discussed, as are factors such as scalability, bandwidth and access.The time has come for remote proofing. Networks, databases, and proofers are capable due to “Moores Law”. However there are still outstanding issues in the color science area and system configuration to optimize results.
