Hi, I just did a tradeshow display in Affinity Designer. Back ground is full black and built to a rich black as specified by the output shop. C30, M20, Y20, K100. Using export persona or just the export to PDFx, the rich black information is lost and ends up being C63, M52, Y49, K91 when checked in output preview in Adobe Acrobat. Vendor is flagging file as having to much ink density, and it looks like I am either going to have to redo it in illustrator, or export it to eps and try to rebuild it in illustrator. Any suggestions would be highly appreciated. While I love designer as a purely illustration app. it is things like this and few other missing or incomplete features that give me serious reserve as using this app as a professional production tool.
Maybe I’m doing something stupidly wrong, but this is happening on my system, Windows 10, in both Affinity Designer 18.104.22.168 (Beta) and the latest stable release (22.214.171.124). I ran into this while creating a “Rich Black” swatch for a document for printing purposes. To reproduce this, I create a new document using a Print preset — although I don’t think this matters. I draw a square filled with Black from the Grays palette, drag a copy of it on top of it, open the Fill drop-down and switch to “CMYK Sliders”. When I move the Black slider to any value (even slightly) and then back to 100%, I get this dark gray and there’s no way to make it back to black (see attached image). The only way I’ve found to deal with this is switching to another color mode — for example, “LAB Sliders” and wiggling the luminosity slider around and back to zero. But even if I switch back to “CMYK Sliders” afterward, the appearance of black on screen is not the same, the CMYK black being a little duller. Any help will be appreciated! Sergio
