Look in the Swatch Options dialog for the P-tone color. It likely is set for CMYK conversion.
Your color, Pantone P 2-9 U doesn't appear to actually be a spot. Not all Pantone colors are.
Heh heh. I didn't look at the numbers. And the 1788 UP is a bridge color.
but I can't figure out why they don't appear in the separations and don't export as separate plates
The PANTONE + CMYK Coated and Uncoated libraries are process CMYK colors (there are no solid spot inks for the system). I think it's replaced the older PANTONE Process libraries, which had the PANTONE DS prefix.
PANTONE + Color Bridge Coated and Uncoated are also CMYK process libraries, which are CMYK approximations of the Pantone solid ink system.
All of the above are spec'd as process colors. If you need Pantone spot colors you normally would use one of the Solid Color libraries—PANTONE + Solid Coated or Uncoated, or any of the Pastel or Metallic libraries.
Thanks everyone! I never realized that the InDesign list for the Color Bridge swatches was only the UP colors provided in the series and not the U colors. That makes complete sense now.
Do you know if the colors in Bridge listed as U are the same as the Solid Color Libraries? Meaning, would 2905U in my Color Bridge swatches be the same as the 2905U in the Solid Color swatches?
I guess that's a dumb question. If they're the same number, they'd better be the same color, right?
If they're the same number, they'd better be the same color, right?
Actually they are not the same at all.
2905UP is a CMYK mode color and its Color Type is process, 2905U is a Lab mode color and its Color Type is Spot.
2905UP is a CMYK simulation of the 2905U solid ink color and it may or may not match depending on the press conditions. Some solid ink colors can't be matched using process colors under any conditions because they are not in the CMYK color gamut.
On screen they can also look different because the solid color's Lab definition is unaffected by the document's CMYK profile, while the bridge version is because it is a CMYK color.
Here's the solid version on the left and the bridge version on the right with with US Web Uncoated and US Newsprint profiles. The Bridge version is a terrible match under either of those press conditions.
