In ColorManagement/Devices the color management inside PhotoLine is activated or deactivated. Furthermore input and output devices can be calibrated by using ICC color profiles. ICC color profiles are a standard way to achieve a correct color reproduction.
If there are more than one scanners or printers connected to your computer, every device can have a profile on its own. You just have to make the device the standard device. For scanners use File/Import/Select Scanner. For printers you have to use File/Print Setup on Windows.
On Mac OS X you can't change the screen and printer profiles in this dialog, because on Mac OS X the system wide defined profiles are used. These can be changed by using the ColorSync Utility.
The profile selected in Digital Camera is used, whenever a Raw file is loaded by using File/Open instead of Digital Camera Raw Data (see chapter 7.1.24).
Additionally you can define a proof profile. The proof profile allows to emulate the output of a certain device on your screen and on your printer. In order to do this you have to activate Proof Mode in the menu View.
