Not quite and explained in the URL provided. But yes, there is one critical setting you must confirm as active each time.
Andrew, I have read your very helpful PDF on the link you provided. For the sake of clarity and, hopefully, to help others may I add my observations in relation to Canon printers ?
The experience with Canon printers is different from yours with Epson. This has been replicated by Canon UK under both Sonoma and Sequoia and videos of this behaviour have been sent to Canon in Japan.
When ‘application manages colour’ is chosen there is no option to select either ColorSync or Canon Color Matching in the print dialogue. This option is greyed out. If a printer pre-set has
not been saved then ColorSync is selected. All is well.
When ‘application manages colour’ is chosen, and a printer pre-set
has been saved, there is no option to select either ‘ColorSync’ or ‘Canon Color Matching’. This option is greyed out. But ‘Canon Color Matching’ is selected by default. In the Apple dialogue this then allows the user to select the ‘Rendering Intent’ of either ‘No Color Correction’ or ‘Perceptual (Photo)’.
‘No Color Correction’ produces prints with inaccurate colours somewhat reminiscent of printing without any colour management.
‘Perceptual (Photo)’ produces acceptable looking prints but Canon UK’s technical support assures me that this is not producing prints where the application is only managing the colour. Exactly what is happening here is obscure.
Canon in Japan have said that they have investigated and found that the fault lies with Apple programming and they have reported this to Apple as a bug.
The current advice from Canon is not to save any printer pre-sets, thus the need for a pen and paper.
