Illustrator cc 2017.1.0 soft proof does nothing
I'll trying to create a reliable soft proof environment across Illustrator, Photosop, InDesign. I work on a Retina iMac and have Calibrated my monitor using a Datacolor Spyder5 colorimeter. A good deal of my work is for press print in the UK so I have my Adobe CC apps synced via Bridge using the Europe General Purpose 3 profile.
My Illustrator Proof setup settings are:
• Proof setup > Customize
• Device to simulate: Coated FOGRA 39 (ISO 12647-2:2004)
• Simulate Black ink: ticked
If I select proof colours (making the menu item ticked) it has no affect on the appearance of my artwork whatsoever. If I tick 'Simulate Paper Color' this also has no affect. Here is a screen grab of 2 overlapping squares, one set to cmyk super black (40, 30, 30, 100) and the other to 100% K only, proof colours shows no difference between the two. Am I missing something or does soft proofing not work?
