One example relates to a print system for adjusting a color profile. The print system can comprise a system comprising a memory for storing computer executable instructions and a processing unit for accessing the memory and executing the computer executable instructions. The computer executable instructions can comprise a profile transformer to receive a color sample comprising a color measurement of a proper subset of a gamut of colors printable with ink deposited at a printer. The profile transformer can also provide an adjusted color profile for the printer based on (i) an original color profile associated with a substrate for the printer and (ii) the color sample.
