![]() ![]() Note that many Pantone spot colors cannot precisely be matched in process color simply because such colors are outside the gamut of whatever process CMYK color space your printing workflow supports. This is the method getting precisely what Pantone defines for the spot colors and how they will look in process color. PANTONE COLOR CONVERTER TO CMYK PDFOn PDF export, all references to PANTONE 322 C will be output to the PDF with the exact LAB color values which your RIP will convert to CMYK and no references to the spot color at all. If you know that the press definitely won't have the spot colors, set the Ink Manager as follows: In this case, the RIP will use the spot color if available or if not, it will convert Pantone's more precise LAB color values specified as the “alternate color space” to the press' CMYK color space. If you are actually printing spot color or if you don't know whether real spot color inks are available, set the Ink Manager as follows: ![]() When you export PDF, you have two choices. Preferably, you are using a PDF/X-4 workflow. You didn't indicate what your full workflow looks like, but the most reliable method of dealing with spot colors, whether used as real spot colors (i.e., you actually have those spot color inks at the press) or you are simulating them, is to pass through the spot color information in the PDF file exported from InDesign or at least as LAB colors otherwise. Yes, Pantone provide CMYK equivalent values, but in exactly what CMYK color space? According to what I have been told by Pantone, those CMYK values are nominally SWOP. Part of the “problem” is that of how you actually represent the Pantone spot colors. ![]()
