kaffeeundsalz Posted October 8, 2019 Share Posted October 8, 2019 Hi there, Here's some really odd behavior that I just noticed after I added a Gradient Map Adjustment: I pick a gradient node, switch the color picker to CMYK and play around with the sliders. What happens next is that the color of the node is completely different from the color in the color picker. Please see the attached screenshot for an example: I first thought it has something to do with my color management settings, but it hasn't because it only happens with the Gradient Map adjustment. In all other gradient dialogs, for example Fill or the Gradient Overlay Layer Effect, everything's fine. It also doesn't matter what Color Profile is set for the document. This happens in the latest versions of all three Affinity apps. Can anyone tell me what I'm doing wrong? Quote Link to comment Share on other sites More sharing options...
Staff Dan C Posted October 8, 2019 Staff Share Posted October 8, 2019 Hi kaffeeundsalz Thanks for your report, I've been able to replicate this here and I can confirm it affects Mac only. I've tried changing from Metal Compute to Open GL, however this hasn't alleviated this issue. I'll get this logged with our development team now, many thanks for bringing this to our attention!

kaffeeundsalz Posted October 9, 2019 Author Share Posted October 9, 2019 Thank you @Dan C. I had hoped that I had just missed a setting or so. That's why I didn't post it directly in the bugs forum section. Glad I could help. Quote Link to comment Share on other sites More sharing options...
kaffeeundsalz Posted August 4, 2020 Author Share Posted August 4, 2020 Any chance this could be brought to the developers' attention again? The issue is still not fixed with the 1.8.4 updates. Here is a different description of the same problem: Quote Link to comment Share on other sites More sharing options...
Staff Dan C Posted August 7, 2020 Staff Share Posted August 7, 2020 I've bumped this again with our developers and included a link to the forum post above - unfortunately there's no further updates regarding this issue I can provide currently, my apologies for any inconveniences caused.

hannah Posted May 23, 2022 Share Posted May 23, 2022 Unfortunately I am still experiencing this painfully persisting problem (MAC, Publisher 1.10.5): Something with the gradient map in cmyk is not working, especially in the blues and greens. It makes some basic graphic design moves impossible: The bar on top of the typo should 100% match the background-black in the dark areas, but it's completely shifted to the blue. It's so frustrating and at best, time-consuming if not impossible to find different solution. Quote Link to comment Share on other sites More sharing options...
hannah Posted May 23, 2022 Share Posted May 23, 2022 There is a somewhat effortful workaround I found for matching my blacks to a predefined rich black (lets say 60/40/40/100). + You've to start with a K-only image or use the black-and white adjustment layer. + Then you can use the Channel Mixer and give each colour the desired value on the "black" slider. So for Cyan the output channel would be 0/0/0/60. For Magenta it would be 0/0/0/40, etc, etc, etc You can see in the picture that the second rectangle merges now into the background. It solves my specific problem, I hate it though! Otherwise LOVE the programs ssssaaaa and Dan C 2 Quote Link to comment Share on other sites More sharing options...
Staff Dan C Posted May 23, 2022 Staff Share Posted May 23, 2022 Hi @hannah, Many thanks for the update & I'm sorry to hear you're affected by this issue. I can confirm this is logged with our development team as a bug, so I will be sure to 'bump' this with them now & add the above provided information regarding the Channel Mixer workaround, to hopefully assist in the issue being resolved ASAP I hope this helps hannah 1 Quote Please note - I am currently out of the office for a short while whilst recovering from surgery (nothing serious!), therefore will not be available on the Forums during this time.

ssssaaaa Posted February 21 Share Posted February 21 Would like to bump this issue as well. Didn't understand what was wrong. Quote Link to comment Share on other sites More sharing options...
ssssaaaa Posted February 21 Share Posted February 21 Another way to go about this is (if you like me are converting to a CMYK profile) is to export your print in a RGB profile and convert it using Acrobat or another converter. Then you'll have a file with better mapped colours. Quote Link to comment Share on other sites More sharing options...
Staff Dan C Posted February 22 Staff Share Posted February 22 Hi @ssssaaaa, Sorry to hear you're having trouble! The issue reported above was with regards to the Gradient Map Adjustment when using the CMYK colour options either not updating correctly on the adjustment, or not correctly converting the colour values when applying to the document - however the screenshot you've provided above appears to be a different issue altogether. I'd recommend creating a new thread for this issue, including a copy of your Affinity document so our team can investigate further Quote Please note - I am currently out of the office for a short while whilst recovering from surgery (nothing serious!), therefore will not be available on the Forums during this time.

ssssaaaa Posted February 26 Share Posted February 26 Hi Dan C The image in my screenshot is Gradient mapped and should appear like the colored boxes in the front, so it seems to me like it's this issue and not a new one. Sorry I didn't describe what the screenshot was showing in my original reply. Quote Link to comment Share on other sites More sharing options...
Staff Dan C Posted February 28 Staff Share Posted February 28 As mentioned, the initial issue reported here is for V1 and relates to the Sliders in the Gradient Overlay Adjustment, not the results that the Overlay Adjustment is providing for you. Please create a new thread for this issue, including a copy of your Affinity document to enable our team to further test and log this issue as required.
