Hi,
having worked with vector packages from the early days of Corel Draw for Windows, I consider myself having quite a grasp of coloring, CMYK values, separation for print and whatnot.
But with Affinity Designer a problem is introduced that I have never encountered in any other vector app: The CMYK values seemingly being transformed using RGB color profiles and turning out something completely different from what I intended.
While in other packages exporting a 100% K renders just that: complete blackness, a 100% K surface from Affinity seems to result in a greyish almost-black (and if exporting to a bitmap format, 100%K transforms into 94%.)
This seems to be the case regardless of export format.
Is there any documentation for how to use color values in Affinity, and how (or why) conversion takes place?
Can it be turned off?
Or is the CMYK color model in Affinity Designer only there as a coarse guideline, translated internally to and from RGB even if my intended use is printing?
Any help and explanation greatly appreciated.
(Case in point: Yes, you could argue that 100%K on paper isn't as rich and totally black as K with some percentage of CMY — but being a vector app, I want to be able to design a logo with a BLACK element — to be printed with K only — then print it as vector in complete blackness while also exporting it to, say, a web page header, with the black element still being completely black. This seems, confusingly, impossible with Affinity Designer today. Am I right?)
