Why calibrating and profiling?
When working in RGB or CMYK, you’re actually not talking about color perception. The only statement that is made with these color systems, is a percentage of a maximum.

As you probably now, all devices have their own way of dealing with colors. Therefore, when using equal percentages (eg. 50% Cyan) printed on two (or more) devices, you’ll face different color perceptions (You can find more info on the main part from this site).

ColorManagement Systems (like Apple’s System Level ColorSync) deal with these different color behaviors by using device specific color profiles to transform color perception from one device to another.

While many manufactures install default factory profiles inside your ColorSync profiles Folder (/Library/ColorSync/Profiles), it’s our experience that you will achieve better results when you build your own custom profiles (check out the section on profile quality for this).

In the past, profiling solutions were expensive and sometimes difficult to use, but in the past years manufactures developed less expensive and more intuitive solutions for ICC profile creation.
