Pantone Connect will display CMYK values on colors that are based on printing CMYK. Such as the Pantone Color Bridge colors and Pantone CMYK Color Guide colors. To see these values, in Pantone Connect when you click on any color it will open the color’s menu. This will have the COLOR DATA option in which this will open the color’s data such as RGB, Hex, L*a*b* and CMYK (where applicable).
Using an example, the CMYK print simulation of Pantone 100 C is Pantone 100 CP (found in Color Bridge Coated). This will display the CMYK build associated as this is the CMYK simulation of Pantone 100 C.
