Xerox 2000 manual RGB colour charts, Appendix

APPENDIX 2:

RGB colour charts

The RGB colour space (or gamut) is much broader than the gamut of a process colour printer or press. Consequently, many colours available in the RGB colour space cannot be reproduced on a process colour device.

A common area of discontent with customers is the issue of colour conversion from RGB to CMYK, ie, the colours they see on their display and the same colours as they appear on the printed page. Most customers who work in the office environment do not understand colour and how it is produced and/or reproduced.. A typical complaint is: "My PowerPoint background is blue – why is it printing as purple?"

The following charts can be used as a guide to how RGB colours are reproduced on the DocuColor 2060. Each chart has a fixed percentage of red and a mixture of green and blue in stepped increments.

Due to differences between individual DocuColor 2060 digital colour presses, machine set-up (eg screening), RIPs, RIP options, calibration used, environment, and papers used and their condition, these charts should be used as a guide only. The following charts may differ somewhat from the printed results you get on your DocuColor 2060.

Therefore it’s important that you make sure you print these charts on your DocuColor 2060, utilising your RIP, settings, calibration and paper to give to clients for colour selection and matching.
