What is the correlation between color profiles and anti-aliasing gaps when shapes overlap?


Recommended Posts

This problem gave me a headache, but it seems that the problem usually appears in CMYK documents, and the problem seems to be almost solved just by assigning or converting the color profile to another CMYK profile.

Since the problem does not occur even after returning to the original profile, it seems that the problem is not caused by a specific profile, but is related to the profile replacement action.

Assigning a different color profile will alter all colors, especially black, from pure black (100%K) to "rich" black (mixture of all colors with 75%K).

This happens e.g. when switched from coated to uncoated profiles. 

You can achieve the same effect by manually setting the text color to "rich" black. Changing color profiles does this as side-effect.
