When I convert PANTONE colors to CMYK in Adobe software, the results do not match the values in my PANTONE COLOR BRIDGE guide. Why is this?
The PANTONE COLOR BRIDGE digital libraries provide explicit CMYK conversions which are consistent with the CMYK data published in the PANTONE COLOR BRIDGE guides. The most current libraries are provided in PANTONE Color Manager software and can be exported to the Adobe applications. PANTONE Color Manager is a free download with registration of qualifying PANTONE products.
In the Adobe applications, if you pull up a solid PANTONE color and ‘convert’ it to CMYK, you will achieve converted data based on the color setting and algorithms used by the software. This data will differ from the explicit data provided in the PANTONE COLOR BRIDGE guide and accompanying digital libraries.
If your intention is to output CMYK separations which are consistent with the PANTONE COLOR BRIDGE guides, you should be selecting your colors from the PANTONE COLOR BRIDGE libraries, as opposed to selecting colors from the solid color libraries and converting to CMYK.
