Among various embodiments of the present disclosure, color calibration can be performed on a printing apparatus by using a preconfigured color map coded to reduce a color difference of a selected reference color sample relative to a color standard, where the selected reference color sample substantially matches a first test color sample printed by the printing apparatus. Installing the preconfigured color map can enable recalibrating the printing apparatus to use the preconfigured color map in adjusting an amount of a number of colorants utilized in printing a second test color sample to reduce the number of color differences of the second test color sample relative to the color standard.
