Abstract: An example color resource is generated. A source color from a first color space is converted to a corresponding greyscale color in a greyscale color space. The greyscale color includes a first luminosity amount. A black channel amount is adjusted to a depletion color from a second color space to form a target color in the second color space. The depletion color corresponds with a transformation of the source color into the second color space. The depletion color includes a second luminosity amount, and adjusting the black channel includes matching the second luminosity amount in the target color with the first luminosity amount.

Abstract: Example printing devices and methods of the printing devices are disclosed. Target data is received responsive to imaging the source item. The source item includes a mark indicative of rendering information. The target data is used to detect the rendering information. The target object is output based on the target data and the rendering information.
