There's a much easier solution, though, than slaving over test-prints and re-renders. Hope this helps you, Foleypro, there's a lot of What-you-see-is-what-you-get software available, the best one I've found is Colorific for Windows. Any professional setup not using at LEAST Colorific is, well, amateur. (A big "screw you!" to Kinko's!) It creates color correction profiles for monitors, and standardizes output for both print and monitors. It will process all of the math necessary to convert RGB to CMYK, internally, and with little or no intervention from the user. I've been using it for years, over several platforms, and countless monitor/graphics card/printer setups. Flawless. Give it a try, if the Renderosity printers aren't using it yet, tell them to get on it.
