My Canon Pro 1000 printer has suddenly started printing colours incorrectly. The colours are generally muted and particularly noticeable with blues / turquoise. Whatever compensation I make in the edit, just makes it worse. I'm on a Mac and use Lightroom. The same thing happened a couple of years ago and an OS upgrade and re-installing the driver resolved the issue. This time I've tried the following to no avail: checked ink cartridges (genuine Canon), Print head alignment, Nozzle check, monitor calibration, upgraded from Ventura to Sonoma, removed printer, deleted printer driver, reinstalled printer driver, reinstalled printer, restarted laptop - but still the print colours are incorrect. I have also spent 2 hours on the phone to Canon and had my case escalated - with no solution. The guy at Canon seemed to think there was a compatibility issue with Sonoma and that it was an Apple issue, but the problem arose when I was still on Ventura after 2 years of working perfectly, so that's not the issue with me. I'm at my wits end, so any help or advice would be greatly received. Thanks in advance.
