Before you need
Before you install CMYK support for The GIMP, you need to know if you really need it.
There has been much debate about the merits of using The GIMP. Most of the heated discussions revolves around the fact that The GIMP does not support CMYK mode. However, you have to understand that the topic is more important to DTP professionals than other users (photographers, web artists, home users). CMYK color model (or CMYK mode) is used mostly by DTP professionals that need to output images intended for printing on a commercial press. For an average home user or even professional photographers, support for separating images using CMYK color is not necessary. Most ink-jet and color laser printers print color images using sRGB color, so you don't really need CMYK color for that either.
You will need root access in order to install the plugin.
Note on Adobe ICC profiles

The zip files (Windows version is a zip file, and it is the prefered way to get ICC profiles) are located at Adobe's [support page].
