I had a very interesting discussion with a Canon tech this morning. Claims that Apple made them change the 4.50 driver.
What he proposes with the 4.50 driver is this.
With PS choose Printer manages color then go to setting, Under Color matching choose Vendor Matching then in Main/Color Mode choose No color correction and ok that. Then choose Photoshop manages color and choose your output profile and print.
With LR choose Printer manages color then go to Printer Setting, Under Color matching choose Vendor Matching then in Main/Color Mode choose No color correction and ok that. Then choose Lightroom manages color and choose your output profile and print.
Anyone with the 4.50 driver loaded please test this, as I don't see this working because I would think as soon as the you go back and choose application manages color it will default to colorsync.
I don't want to load the 4.50 driver just to test this based on what I have already done that I explained in previous posts.
I tried this and it worked like a charm! Then I tried it again the next day, twice - in case I did something wrong the first time... and it did not work (mushy colours).
I thought I would check it once more before I posted this and..it worked properly again! (Make a small proof first.)
In the imagePrograf Advanced Preview you can do a final check at the top right-hand corner to ensure color is still off.
I now print through the iPF8400 Print Plug-In in Photoshop with no "colour" problems, although Lightroom would be far more convenient, especially with multiple images.
Anyway, work-arounds are bullshit and I find it very sad that these massive companies don't give a damn about their customers. History shows us that they will all fail in the end.... and I won't shed a single tear.
