Dear Affinity community, I made my first big project in Affinity Publisher (still in beta, but pre-ordered the whole thing already ) and have an important text-and-graphics element that uses the Contrast Negate filter.
Black text goes through the middle of a one-color vector shape. When I use RGB and the Contrast Negate filter the parts of text that are over the vector element turn white (and that's great - I specifically wanted it to happen) but after I change the document to CMYK - the white part turns grey I show it here on an example: http://recordit.co/s3LvL4xzfc
Is there any way to prevent it? Or is the Contrast Negate inherently flawed to do this task? How can I do it so it's in CMYK, ready for print, doesn't have to be rasterised so it doesn't loose quality, but makes the text on red background white? Is there any way beside Contrast Negate?
Pls help!
