icc profiles missing in Photoshop

You may have missed a step that is not obvious and easy to overlook when you reinstall the printer.

Follow the process in this video -> How to Fix Missing Epson ICC Profiles in Photoshop After macOS Update

The key step is around 2:50 in the video.

FWIW, if you only use Epson papers you can let the Printer Manage Colors and in the Photoshop print dialog just select the Epson paper you are using; the print will turn out fine.

Letting the printer handle the color only works in the sense that it automatically applies color rendering based on nothing more than your monitor profile, the printer's built-in color tables and the paper type you chose. No printer profiles are involved this way.

The video linked to above seems logical, but isn't. The OS had already chosen the correct driver, there was nothing else to do but click Add. You can prove the video is meaningless with any printer. Such as my Xerox VersaLink C405. If I follow the same steps, I get this:

The correct drivers have already been automatically selected. If I click the last drop down menu and choose Select Software, it then shows this:

It looks like it's going to incorrectly install drivers for a DYMO Label Printer. But that's false. All the OS is doing is highlighting the first item alphabetically. That's it. It in no way means that's what it was going to install.

So, where are your profiles? Assuming you used the Epson SureColor P5370, Sequoia drivers from Epson's site…

…they are on the drive, but not where you'd expect to find them.

Go to this folder:

/Library/Printers/EPSON/InkjetPrinter2/ICCProfiles

There you'll find the file EP2310KS1.profiles

Right click on the file and choose Show Package Contents, then the Contents > Resources folders. That's where all of the ICC profiles for your printer are.

Why don't they appear? Quite a few versions of macOS / OS X back, the OS was set up to look in any of the /Library/Printers subfolders for profiles or profile bundles so it would know what to report as available. For the most part, this doesn't work anymore, and hasn't for a while. Such as these for our Xerox printer. These are within the /Library/Printers folder, but none of them appear in any app.

With the folder of .icc profiles still open, copy the profiles to the /Library/ColorSync/Profiles folder. Close Photoshop and reopen it. With the Epson SureColor P5370 selected as the output device, all of your printer profiles should list.

Granted, the Epson .icc profiles are already contained in the Epson driver. And they will show up in the standard macOS print dialog as paper types. But the straightforward driver installation does not copy the Epson .icc files to /Library/ColorSync/Profiles. (This may be intentional on Epson's part or it may be a flaw.) As a consequence the OP can't see them in Photoshop when he/she selects Photoshop Manages Colors and attempts to select a Printer Profile.

The "missing step" as shown in the video appears to force the installer to also copy the Epson .icc files to /Library/ColorSync/Profiles. Once copies are there, the OP can see & select them in Photoshop.

Your suggested alternative of navigating into the Library, finding & opening the profiles package and manually copying the .icc files to /Library/ColorSync/Profiles will work but it's much easier just to do what the video shows.

Correct. But this used to work (quite a few versions of the Mac OS before). Any ICC profiles within the /Library/ColorSync/Profiles folder would appear across the system. It also seemed to be the expected place for vendors to put these files. That stopped working at least four OS versions back. Maybe longer.

I only installed the drivers for our printer straight up. The OS had already selected the correct driver for the Xerox C405, so I didn't re-select it in the drop down menu.

Just now, I followed the steps completely. If that last step made any difference at all, then the handful of profiles in the /Library/Printers folder should have been installed to the /Library/ColorSync/Profiles folder. Or, at least show up in my apps. They don't. Photoshop, Pages, and any app still don't know they exist until I copy them into the /Library/ColorSync/Profiles folder.

As far as I can see, the steps in the video do nothing.

Whoops! Error. I wrote:

Any ICC profiles within the /Library/ColorSync/Profiles folder would appear across the system.

Should have been:

Any ICC profiles within the /Library/Printers folder would appear across the system.

Reinstalled what? If you mean Photoshop, Adobe's installer will not put another manufacturer's profiles on the drive. If the Epson software, they may be there, but not listing due to where the installer put them.

If you don't figure it out before then, I'll try to remember to look into this tomorrow.
