Gradient tool adding black to CMYK blend that should have no black
I work in CMYK mode creating comics and my color swatches all have 0% black. When I try to do a gradient, say from 30% magenta to 40% cyan the gradient tool is adding 4% black to the blend. I have two computers, both running latest versions, but it is only happening on one. I can't see any difference in settings so am baffled as to why this is happerning. In researching this, I noticed someone had the same issue 3 yeras ago but the community didn;' have an answer then ... Hopefully, better luck this time! Any ideas? Thanks!
