Color Profiles installation
Windows OS
To Install Color profile, choose *.icc file and press right mouse button on it. In the pop-up menu choose Install Profile. If this line is in bold, you just need to double click on it and the profile is installed.

When correcting or viewing the Document in Adobe Photoshop, it is recommended to use the same Color profile, which will be used for printing. To open Color Settings window go Edit > Color Settings or press Shift + Ctrl + K.
When the document is for printing, the most important option is CMYK Working space profile:
The profile matching the paper of document should be chosen in the CMYK box. In case when necessary profile is not in the list, the profile should be installed (please see Color Profile Installation).
Also, the profile can be loaded from Photoshop, using setting Load CMYK:
NOTE: The profile installed using Load CMYK is not saved in system color directory and does not stay in the list. This option is recommended only when standard Color profile installation is not possible (for example, you do not have the rights of administrator).

Image Preview Using Paper Simulation
All papers might look white from the first glance, but all of them have some shade. Especially book papers, like Munken. Adobe Photoshop displays images assuming paper has no color. But in fact, printed image colors are affected by paper shade. In the printing house, hard color proof simulates paper color. In Adobe Photoshop there is a feature which enables to get a pretty good idea how the image might look when printed. This feature Paper Simulation can be turned on following: 1. Correct profile should be set (please see Profile Setting in Adobe Photoshop). 2. Go View → Proof Setup and choose Custom.
3. In the pop-up window mark Simulate Paper Color. Also check if correct CMYK profile is set. If yes, press OK. By pressing OK Proof preview mode is activated.
4. To turn on/of Proof preview mode go View > Proof Colors (or press Ctrl + Y).
In Adobe Acrobat Pro there is also a feature which lets to simulate paper color in print-ready PDF file.
To activate paper simulation go Print Production and Output Preview. In the pop-up window set correct Simulation Profile and mark Simulate Paper Color.
