Abstract: Certain examples relate to a method of color matching by confirming a color-rendering device. Color reproduction parameters are determined for a reference and target color-rendering device. A color matching parameter is determined for the target color-rendering device based on a comparison of the color reproduction parameter for the target color-rendering device with the corresponding color reproduction parameter of the reference color-rendering device. The color-rendering device is confirmed dependent on the color matching parameter. Color resources of the target color-rendering device are configured such that a rendering of a color image on the target color-rendering device replicates a rendering of the color image on the reference color-rendering device.

Abstract: A method comprises computing an activity map for an input image. The activity map indicates an amount of variable spatial activity in the input image. The method further comprises producing an output image based on the activity map, and controlling a printhead to cause the output image to be printed. The output image contains a plurality of color pixels and each such color pixel is represented by at least one of cyan (C), magenta (M), yellow (Y), and black (K) in a color space.
