Automatic PANTONE® Matching The printer has a PANTONE Spot Name color matching utility. PANTONE has certified the printer and has mapped the PANTONE Spot Color names to the printer's CMYK values. This color matching utility uses the certified mapping to provide the best PANTONE color matching for the printer. For the color matching utility to function, applications must pass the PANTONE names to the printer. Some applications substitute CMYK values to the printer if they cannot provide PANTONE names. If your application does not pass the PANTONE names to the printer, then the utility will be bypassed and color matching will depend on proper ink emulation. Selection of the proper ink emulation depends on the source of the palette (SWOP (Standard Web Offset Printing), EuroStandard, DIC, or None). The palette used for obtaining PANTONE CMYK values and the driver emulation mode setting should match. CMYK Ink Set Emulation You can select a CMYK ink emulation (SWOP, EuroStandard, DIC, or None - no emulation, device CMYK) from the dropdown menu to provide output similar to an offset press ink set. If color management is active in an application or OS, the ink emulation selected must be the same as when the printer was profiled. EN Controlling Color Output with Printer Drivers 113
