I need to convert image from RGB to CMYK: Black Ink Limit 80%, C+M+Y+K < 280%. In Adobe Photoshop I'm using "Convert to Profile > Custom CMYK". In Photo-Paint I'm using "Export soft proof..." to control conversion, but there is no possibility to set parameters of ink limit.
How to make something like "Custom CMYK" in Corel Photo-Paint?
Ok the way to make this bullet proof is to simply use a CMYK profile in CD that is any of the commercial uncoated CMYK profiles. Conver to that and all is well,
