Abstract: An example method comprises setting a mixture of a plurality of print supplies of a print device to use for a process black print based on a plurality of supply levels corresponding to the plurality of print supplies. The example method further comprises initiating execution of the process black print of a print job by the print device using the set mixture of the plurality of print supply as overlapping colorant with the black print supply of the print device.

Abstract: A video coder includes a processing resource and a non-transitory storage device containing instructions executable by the processing resource to compute a weighted Δ frame based on a saliency map and a Δ frame. The saliency map is to indicate the relative importance of each pixel in a current frame based on its perceptual significance. The Δ frame is to include differences between corresponding pixels in a current frame and a motion predicted frame.
