I see that Pantone troubles are quite common here, but I swear the more I read about it, more confused I am. 🙂
Every time I have to prepare files or create a brand book these doubts come to mind.
If Pantone colours are supposed to be the same why there is a distinct difference on screen between colour bridge coated and solid coated books?
As you can see in the image, some colours (black 7, 171) are quite different. If they are the same shouldn’t they be equal on screen?
Another question is if we should “trust” the RGB values on the Pantone site/guide. For example, the RGB values on the Pantone site for the colour 326 are different for CP and C, and consequently, they look different on screen:
I know that what we see on the screen depends on monitors and calibration. What I want to know is if the Pantone values are like a “safe” compromise value that Pantone come up with or if it’s better if we use the values the program gives us when changing from Pantone to RGB. For example, if I were to choose the 326CP, the program gives me RGB 0 171 170.
Any help with this would be really appreciated.
It all comes down to simulation and managing expectations. PANTONE solid inks like C (coated) and U (uncoated) are only different in the finish of the paper. The ink is exactly the same, but PANTONE’s LAB formula for the on-screen color is designed to represent how that ink will look on the designated paper stock. Uncoated stocks tend to soak up more ink, so the finished product will appear more dull or desaturated.
Bridge formulas are different in that they are not trying to simulate a solid ink, but rather the CMYK representations of a solid ink. However, like the solid formulas, the ideas is the same: the on-screen values should represent as accurately as possible PANTONE’s own on-paper CMYK representation of that solid ink.
