Make sure the color information is adjusted for the current color setup. See Color Accuracy Configuration. Printing color with PostScript (HP Designjet 5000PS) Most graphic design applications can define color using three methods:  CMYK.  RGB.  Pantone. CMYK Workflows Traditional workflows define the color in the CMYK space. To obtain optimal results, CMYK must be adapted to the target printer which receives the data, different printers will produce different color from the same CMYK data. In some situations the CMYK data in your document will not be suited to your printer. Two typical situations are:  The document was optimized for a certain printer, and now it has to be produced on a different printing device.  The document is being optimized for a printing press, but it is necessary to produce a check print using a less-expensive printing device. To process CMYK data which is not intended for the printer, the HP Designjet printers provide color emulation modes. The emulation must be enabled in the PostScript driver, in the "Printer color management" dialog box: Standard emulations: - SWOP (United States), - EuroScale (Europe), - DIC (Japan) and - Toyo (Japan). CMYK data is frequently designed for these standards. If there is no information as to how the CMYK data was defined, these standards are a good assumption.
