--- Comment #1 from heinrich.bo...@gmx.at --- I have created a better sample document to demonstrate the problem more clearly. It contains the same text three times in a row. The middle text has the blend mode set to exclusion and the blending color space set to a CMYK profile. The first and the third text do not have a blend mode. The first text has its color hardcoded to the color that would result from the second text's blend being performed in RGB space, and the third text has the color hardcoded that would result from the blend being perfomed in a CMYK blending color space. Since the second text's blending color space is CMYK, its visible color should match that of the third text, as is the case when opening the file in the desktop version of Adobe Acrobat Reader (but not in the mobile version – this is an intended limitation of the mobile version to simplify and improve performance, so the effect can only be observed when using a desktop version of Acrobat Reader or Acrobat). However, when viewing the file in Okular with "overprint preview" disabled, the color of the second text is very similar to that of the first text, which means that the color blend is probably performed in an RGB space, albeit not the same one that was used in the source file from which the PDF file was created. -- You are receiving this mail because: You are the assignee for the bug.
