All my profiles have degraded and now produce only badly faded prints. Some are from HP and some are my own using i1Studio and their hardware. All worked well about a year ago. The only decent print I now get is using "Let printer manage colors" and the Adobe RGB.
Because this effect happens in Qimage and Afinity and Lightroom I suspect Win 10 updates. Is this a known problem and what might fix it?
Many thanks for any guidance,
Hard to tell what to blame, but you obviously have a grasp of the situation.
Are we talking about camera profiles or printer profiles?
I suspect printer profiles.
Every so often there is a color management upgrade included in Qimage. If memory serves, it is a .dll file like LCMS.dll.
As you stated, Windows 10 updates have messed me up a good number of times too.So my guess, either your profiles are off due to color management upgrades, or they became corrupted during a W 10 update,but Adobe RGB is OK, sort of points to the profiles that you made.
All printers I know of now offer profiles free. Match the paper, and test it.
Hope some of this helps.
