If the Application or Driver settings are not correct, this could result in colors which are different than the one that were expected.

- To have full control of the colors that are printed, use the CMYK option and no emulation (in Driver). Sending a file in RGB even with no color emulation could end up in undesirable results. If a Postscript file is not sent from a DesignJet 5X00 PS driver, make sure you have the following settings in the Front Panel: Printer Setup Menu > Internal RIP settings > Ink Emulation > CMYK= Native.
-As a special case, Adobe PhotoShop sends Pantone Colors as CMYK (no Pantone name). Therefore, Pantone Calibration does not make any difference. The file should be created as CMYK to prevent unexpected color changes.
