Is it possible to mix a percentage of one of the cmyk inks into a pantone color? I know it can be done with bitmaps into a raster editor like PP or PS but just wondering how it can be done with simple vectors, my current workaround is to make an extra shape over a pantone color and fill it and overprint that. but that doesn't always work on complex things like this in the attached image. In the image below I want to add some percentage of Black over the Pantone Orange. From the sample gif you posted it would be easy to set a fountain fill from Pantone Black to Pantone Yellow and adjust the edge pad and fade points to get the effect you desire in one element. Then I remembered you were wanting to apply this to an extrude. I have never worked with extrude so I fiddled around with some of the settings and such and about the only way I could get anything decent was by breaking the extrude apart to then apply a fountain fill separately across the two resulting objects. This at least allowed the use of Pantone and CMYK mixes. It's probably not what you are wanting/looking for, but I've included the PDF sample here just in case. If you're not happy with the extrude gradient, break the extrude apart and apply any fountain fill you want. Hi Miller, first of all thanx for ur keen interest in my question. But watch the difference in the separation of the .gif that attached in my previous post. See how black overprints nicely on pantone yellow, The gif attached in this post is the one from pdf of ur last post. but in the attached gif here yellow leaves white space for the black. Is it possible to make a custom swatch that constitutes of a let's say PANTONE 110 C and 25% CMYK black. and prints the same on separations. CMYK and spot colors are totally different inking systems. You can't have them in a single fountain fill swatch, or as a pair in a single swatch in general.
