ICC Color Calibration
Ever wanted to print something and it looked alright on your monitor but not on your final print? The green isn't quite as green as it's supposed to be and the yellow looks like the green supposed to look?
Here is where color calibration kicks in. You can use an ICC Profile that's suited for your printer and material combination and the color output becomes controllable. There is however one small problem, there are thousands of printer, ink and material combinations possible and you will not always have the correct ICC Profile at hand.
In these cases you have to make your own ICC Profile, but how? There are several separate applications available that are specialized in making ICC Profiles. They have however one big drawback, they are extremely expensive and you will need extra hardware like a densitometer. And a densitometer isn’t cheap either.
