How to find old icc profiles for the Epson 3880 that are installed by the driver but not found by Photoshop

 From Gemini:

Check the "Hidden" Driver Location

On macOS, if you have already installed the Epson 3880 driver, the Velvet Fine Art profile is likely already on your hard drive, but it is "hidden" inside the driver’s library folder where Photoshop and Lightroom sometimes fail to see it.

1. Open Finder and select Go > Go to Folder... from the menu bar.

2. Paste this path: /Library/Printers/EPSON/InkjetPrinter2/ICCProfiles/

3. Look for a file named something like Pro3880.profiles.

4. Right-click that file and select Show Package Contents.

5. Navigate to Contents/Resources/.

6. Inside, you will find the actual .icc files, including the Velvet Fine Art profile.

7. Copy that file and paste it into /Library/ColorSync/Profiles/. Once moved here, it will appear in all your printing applications.
