NotMyFault Posted February 14 Share Posted February 14 Your document is CMYK. This is at least unexpected and a probable cause or co-factor. Having document in cmyk, a rectangle with rgb based gradient, and sampling in rgb again introduces double-conversion (rgb to cmyk, cmyk to rgb) and rich black / K-only black issues.

Hi - I don't understand how that happened. I'd converted to rgb as you said. It seems to have converted itself back! Anyway, is this correct?

NotMyFault Posted February 14 Share Posted February 14 If you have any chance, let someone with IT knowledge check your PC onsite. It seems you find every possible way to creatively misinterpret the advise from the forum. Trying to help remotely via messages and screenshots has its limits.

There is something broken either with Affinity installation or with color profiles in OS. It does not make any sense to test with document or color settings inside Affinity.

Hi @Charles Harris, Try opening this file Gradient test.afphoto, which looks like this to me: Quote Affinity Store (MSI/EXE): Affinity Suite (ADe, APh, APu) 2.4.0.2301 Dell OptiPlex 7060, i5-8500 3.00 GHz, 16 GB, Intel UHD Graphics 630, Dell P2417H 1920 x 1080, Windows 11 Pro, Version 23H2, Build 22631.3155.

- S - Posted February 14 Share Posted February 14 On 1/6/2024 at 2:51 PM, Charles Harris said: This is what I did: Search for Colour Management from the Start menu and click to open. In the Devices tab, select the correct monitor from the Devices dropdown menu and make sure Use my settings for this device is selected. Now click Add... and select sRGB IEC61966-2.1 from the list and click OK. The sRGB IEC61966-2.1 profile should now appear in the Profiles associated with this device: section. If there is already a profile associated with the monitor, please use the Remove option first, to ensure the monitor is using the newly appointed sRGB profile. Select the profile and click Set as Default Profile to make it the default. Close the Colour Management window and restart your Affinity app. What else do you recommend? The sRGB ICM profile in your screenshot is listed under "ICC Profiles (Advanced Colour)". Therefore, remove the "sRGB IEC61966-2.1 (default)" profile and add it again without ticking the "Add as Advanced Colour Profile" tick box. This alone is likely not causing your issue, however it will cause a problem in combination with other settings, therefore it needs changing. Secondly, it appears a faulty ICC/ICM monitor colour profile is still being used from somewhere, which is odd as it should now be using the generic "sRGB IEC61966-2.1" profile that you've set as the default Windows colour management profile. Therefore, click on the "Advanced" tab in Windows Colour Management and check what's listed for the "Device profile" (as per below screenshot). Finally, on the Windows Colour Management "Devices" tab, the top dropdown menu currently shows Display 1. I assume you're only using one display and there's not a Display 2 listed as well?

Amazing, - S - Thank you. I think you've solved it. I don't know what you asked me to do that I hadn't done earlier, but it's now showing greyscale perfectly. And you explained what I had to do very clearly, which made your instructions easy to follow. Thanks again. Fingers crossed that it will stay that way now. And thank you for everyone else who had the patience to try to help with this thread too. I appreciate your time and care. Quote Link to comment Share on other sites More sharing options...
