![]() Guess what happened? Automatically the intent on the left changed to Absolute Colorimetric Intent. I saw that the values on the left and right were identical (so now I'm converting from Lab since Lab is chosen on the left). ![]() I then changed the colorspace on the left to Lab and the intent automatically changed to D50. I wanted to check the values, so on the right I changed the colorspace to Lab. ![]() That translates (after moving the decimal two places to the right) to CMYK 25.53,16.01,13.78,0.01. The CMYK values I got (what I need to get close to the correct color on the print) is CMYK. In ColorSync Utility Calculator, on the right, I chose CMYK, GRACoL2006_Coated1v2, and Relative (because Absolute wasn't available, and although I wouldn't expect the intent chosen on the right side to actually make a difference in values given, it does make a difference for some reason). For instance, I had CMYK values 37.25,21.57,17.25,3.92 in Illustrator and so I put in CMYK. In ColorSync Utility's Calculator, I saw that the max CMYK value that can be put in is 1, so I had to take the CMYK values given in Illustrator, move each value's decimal two places to the left and put in those values for my CMYK. There on the left I chose my color space I'm converting from: CMYK, chose the ICC profile I'm converting from: Photoshop 4 Default CMYK, and chose the Absolute Colorimetric Intent (to get printed values I'm converting from, which is the closest to the Lab values I'm gonna get it looks like since I can't get the Lab values of the PANTONE TPX colors - and I'll say this is not the best way to go about it). So I opened ColorSync Utility and went to the Calculator tab. But which profile? SWOP or Photoshop 4 Default CMYK? Well, since the images were tagged with Photoshop 4 Default CMYK ICC profile, I assigned that ICC profile to the CMYK values of the TPX colors (it's just a guess because when you don't have the Lab values and ICC profiles aren't embedded, who really knows what it's supposed to look like).Īfter reading the post mentioned above, I decided to work with the Mac OS X ColorSync Utility's Calculator to get my "correct" CMYK values for GRACoL2006_Coated1v2. So the next option was to assign the correct ICC profile to the CMYK values given for the PANTONE TPX colors in my Illustrator document. ![]() I couldn't find the Lab values for PANTONE TPX colors. Today I decided to see if I could get the Lab values for the TPX color(s) and then convert them to GRACoL2006_Coated1v2 to get my CMYK values. But I also get most stuff in as SWOP or untagged. What to do to make sure the colors are close to what the customer intended? Well, most of you know that I've said many times that I don't color manage incoming CMYK. I couldn't get the Lab values in Illustrator since I don't have the PANTONE TPX library. The Illustrator document was not tagged with a profile (so assuming the default SWOP profile), but the images were tagged with Photoshop 4 Default CMYK ICC profile. This job also includes PANTONE TPX (Fashion and Home Textile) colors spec'd as Spot but given CMYK values. The question was concerning RGB, but I have a job in today (one of the rare ones that actually use Photoshop 4 Default CMYK ICC profile for everything, and really I just need to get with this customer and get us both on the same page as far as what profile to use throughout). I saw a question about how to get the right color on
