You can assign a color profile, providing you have it as a file something.icc
For that epson sRGB profile I do not suppose it is much different to the built in sRGB.
edit: If you cannot find the icc profile on your computer, you can download from Epson.
All sorts depending on printer and paper. see: https://i.imgur.com/GxHLSg1.jpg
best of luck
Quote:Are there CMYK profiles that files have? Like if I open design for print with CMYK profile, must I convert it to RGB to work with it or I can work without conversion?
The goal is to have completed project print-ready.
When it comes to CMYK, that is a whole different matter. Gimp is a RGB editor and does not support CMYK editing. There is an ancient plugin separate+ that will convert to and export a CMYK image. Very much a last operation when everything else is finished.
There are other ways to convert RGB to CMYK - ImageMagick is one. If you need something with a GUI then use the free application Krita. There are also free online converters.
