Printing from Photoshop and printer profiles are gone for Epson SureColor P600

Epson printer profiles are missing in Photoshop manages color in the print dialog 

To use "Photoshop Manages Color" properly (to make accurate prints) you need access to the printer manufacturer's paper specific profiles, since you need to select the relevant paper profile in that dialog.

Using "Printer Manages Color" should work for Epson’s own papers, as long as the printer driver is correctly installed. 

Printer Manages Color [based on the media type selected] calls upon ICC printer profiles from a different installed folder* 

[*usually a hidden one, this is so they don't get deleted inadvertently, more on that and how to find them below].

Epson ICC printer profiles may be missing in Photoshop after updating macOSX. This issue started with Mojave.

Adobe’s tips:-

To resolve this issue, reset the printing system in your Mac's system preferences and then add your Epson printer again. 

1. Reset the printing system.
   For instructions, refer to Apple's support documentation: https://support.apple.com/en-us/HT203343#reset
   
   
2. Add your Epson printer again.
   For instructions, refer to Apple's macOSX User Guide documentation: Add a printer on Mac
   
   
   
3. Relaunch Photoshop.

When you select Photoshop manages color in the “print” dialog, the “printer profile” dropdown should now provide you with a list of all the ICC printer profiles on your system. If not please read on.

The Epson installer puts them in hidden folders, but normally Photoshop can access them via a hidden link.

You may be able to find the profiles manually in the folder hierarchy 

Are you working on a PC? If so, you may need help from Epson's support team. 

Here are some Mac tips for when Photoshop can't find the Epson profiles:

I had to search for these myself on a client site once, took me quite a while and a lot of head scratching. But it means I now know how to find them

Basically, the printer profiles are in a folder hidden away in the system “library”

Navigate to

“Your hard disk name”/library/ printers/EPSON/InkjetPrinter2/ICCProfiles/ [hidden inside a “package”]

[Not in the “your username”/library/ ]

Screenshot below

Inside the ICCProfiles folder (see above) is another folder containing the printer name, e.g:  Epson Stylus Pro 4900_4910.profiles

If you right click [or ‘control’ click] it and select "show package contents"

A contents folder appears

Now look inside that folder and you’ll find the ”resources" folder. 

see screenshot below

These are the icc profiles which used within the Epson driver [e.g. when you select Photoshop’s printer colourmanagement], 

DO NOT DELETE OR MOVE THEM. It’s OK to copy of course.

SO - don't drag to move them as this actually removes them from the original folder

You can copy to your normal ICC profiles folder which is in the system library

[ computer name/hard disk name/Library/Colorsync/Profiles ]

Restart Photoshop, can you now see the profiles you copied across in Photoshop’s print dialog under "Photoshop manages color"?

I hope this helps

Happy Printing

Many people are running into this problem, constantly. It isn’t a Photoshop problem specifically, because it’s been seen in other applications too. The official Adobe response is to reset the macOS printing system and add the printer again.

However, resetting the printing system is kind of a drastic step if you have several printers installed with customized settings, because a macOS printing system reset wipes out all of that. Sometimes it’s enough to just delete the Epson printer and add it back in. If that doesn’t fix it then go ahead and reset the whole printing system.

But even with a printing system reset, my Mac continued to “lose” the profiles again and again, and I got tired of deleting and reinstalling the Epson printer. The solution which has stuck (so far) for me is to create an alias (shortcut) to the printing profiles deep within the Epson driver, and put them in the macOS ColorSync folder. If you want to try this solution, keep reading.

In the Mac Finder:

1. Choose Go > Go to Folder.
2. Copy and paste this path into the Go to Folder dialog box, and click Go: /Library/Printers/EPSON/InkjetPrinter2/ICCProfiles/
3. There should be a file in there with your printer’s name on it ending in “.profiles”; mine is called Pro3880.profiles because I own a 3880. I don’t know how the one for the P600 is named. Right-click that file and choose Show Package Contents.
4. If you see a folder named Contents, double-click it. You should now see a folder called Resources. That contains the Epson printer profiles.
5. Now open a second Finder window, choose Go > Go to Folder again, paste this path and click Go: /Users/[your_username]/Library/ColorSync/Profiles
6. Put those two windows side by side.
7. Hold down Option and Command as you drag the Resources folder from the first window and drop it in the Profiles window. This creates an alias to the Resources folder in the Epson printer driver software. I renamed it to be more descriptive (“Epson 3880 profiles” in my case).

Since I created that alias to lead ColorSync directly to the profiles, the Mac hasn’t lost track of the printer profiles.
