Question

Color swatch changes by Illustrator – Color profile issue

Hi Adobe Support,

6 month ago, I created a 2 color logo in Ill. 2019. For both colors I created a CMYK swatch which has the correct color values. My color profile is ISo coated v2. After upgrading Illustrator to 2020 I opend the file and it told me that the assigned color profile now is US Web coated. I have 3 choices to proceed. If I choose to change colors into my normal ISO coated v2 profile, Illustrator changes the swatch color values from 100/0/100/15 to 97/1,37/92,25/4,8. Why would the color swatch value change if the color profiles (both CMYK) change? Any Ideas?

Kind regards, Katja

If you do not want your color values to change (converted), choose "Use the embedded profile (instead of the working space). 

Check your Edit > Color Settings and make sure that the working space is still your ISO profile.

If that is the case, a different profile was used (or has been assigned) for the file you want to open.

Converting between (CMYK) profiles will always result in different color values. Because you will convert from CMYK (4 colors) to Lab (3 color components) to anothe CMYK (4 color components).

    Thanks for the reply 🙂 I am using Illustrator for more than 20 years and never had this issue. On opening the document with the wrong color profile, I choose to switch the profile to ISO_Euroscale – the colors change. If I don't change the profile and open the dokument, the colors stay as they should. Then, I change the profile to ISO_Euroscale, the colors also don't change. Is it the same process with 2 different outcomes?

    On opening the document with the wrong color profile, I choose to switch the profile to ISO_Euroscale – the colors change.

    If you switch the profile on opening, you will convert the document profile to the current working space profile and that will change the color values.

    If I don't change the profile and open the document, the colors stay as they should.

    The color values (numbers) stay as they were, no conversion takes place, but the color appearance may be (more or less) different. The values are displayed as if they were entered with the current working space profile. 

    Saving a document with an unchanged profile will keep the original profile with the document.

    Then, I change the profile to ISO_Euroscale, the colors also don't change. Is it the same process with 2 different outcomes? 

    If you Assign a profile you don't change the color values (numbers) but tell Illustrator to use those numbers with a different profile. which can change the color appearance which may not be noticeable when you switch between 2 different Euro  CMYK profiles. 

    Saving a document with an assigned profile will save that profile with the document.
