I am researching an issue that popped up with a couple of files and want to get some expert input. I have two different files supplied by the customer that has a CMYK swatch with the build of 72,91,38,28. As far as I can see, there is nothing special with this swatch in either document.
We had a customer requested change to these files. Nothing to do with color. In both of these files, the color build “mysteriously” changed to build 76.078, 94.118, 38.824, 45.098 in both of the Indesign documents. Quite the color shift. The operator that did the changes says he did not change the color, has no clue how it changed, and can recreate the issue.
I only know of two ways for a swatch to change. A script or opening the swatch and changing the colors. Are there other ways? Maybe keyboard shortcuts, or the eyedropper, anything? I don’t want to think that the operator did it and is just denying it, but I can not reconcile this happening in two separate documents, to the same swatch color, without it being on purpose.
Wow, that is very strange. Another way color swatches can change is if you choose Edit > Convert to Profile. Or if your color settings are set to show a dialog box if the color profile is different (than the file you’re opening) and someone chooses Convert to Profile. These are rare, but they could happen. In general, there are very few good reasons to use Convert to Profile (and many reasons not to).
Actually, I just tested and the Profile Mismatch dialog box (when opening a document) doesn’t offer “convert to profile”… my mistake.
But if the color management policies (inside Edit > Color Settings) were set to Convert to Working Space, this problem might happen when you opened a document. Swatches could change. (Not normally that dramatically, but certainly enough to be a shock.) In general, you want the policies to be set to Preserve Numbers (ignore linked profiles).
Yes, the second issue I mentioned — where the profile mismatch checkbox is turned off, but the color management policy was set to Convert to Working Space — would affect the file without any warning. Dangerous!
Thanks for the help.
The setting you mentioned are how we should be set up. In fact, I have an applescript in the Indesign start up folder that ensures the settings are correct every time Indesign starts up.
