Review on DGK Color Tools DKK Calibration by David Bar

Thought I could save a lot of money by buying these cheap smart cards. I spent a lot of time calibrating them. You can use them to compare light from setup to setup, but they are not useful for camera calibration. The chips are CMYK assemblies, not spot colors, so don't expect them to match RGB values at all. THESE ARE DEFINITELY NOT STUPID COLOURS! The gray tones are also a little patchy. In addition, a matte instead of glossy surface would have been much better. They packed them for UPS this morning!
