WolfBearAlpha Posted February 5, 2020 Share Posted February 5, 2020 When I create a CMYK document and place an object with a drop shadow (blending mode normal) the shadow looks different against the white document canvas versus a white rectangle placed behind the object. This only happens in CMYK mode, the appearance in RGB mode is correct. I expect the white document canvas to behave exactly like a white filled rectangle spanning the dimensions of the document, but this is not the case. Other effects, like outer glow an other blend modes that "normal" show even weirder behaviour... looking very different or not being visible at all. The bug exists in Photo (Mac, iPad), Designer (Mac, iPad) and Publisher (Mac). Most likely on Windows, too, but I could not test that. Please look at the provided image.

Staff Gabe Posted February 6, 2020 Staff Share Posted February 6, 2020 Hi @WolfBearAlpha, Welcome to the forums. Thanks for spotting this. I logged it with our developers. I believe it's a bug with the way FX are treated agains alpha and white. A white background is not technically white, but transparent with a white Alpha.

Sydney2021 Posted September 27, 2021 Share Posted September 27, 2021 Has this issue been fixed? I have perfect drop shadows in RGB mode in my final PDF, but they disappear from the CMYK PDF. I am using the latest version of Publisher. Quote Link to comment Share on other sites More sharing options...
Staff Gabe Posted September 27, 2021 Staff Share Posted September 27, 2021 I'm afraid it has not been fixed. Sorry. Quote Link to comment Share on other sites More sharing options...
