Abstract: An example method comprises identifying a plurality of supply levels corresponding to a set of print supplies of a print device. The example method further comprises coordinating depletion of the set of print supplies by selecting between black print and process black print for a print job of the print device based on the plurality of supply levels.

Abstract: In an example method, an image of a printed document is descreened. The descreened image is separated into blocks. A smooth area of the descreened image is selected based on an averaging of localized color distance values of pixels in each of the blocks. A streak in a block of the smooth area is detected in response to detecting that a magnitude of a color distance projection of the block exceeds a threshold value.

Abstract: According to examples, an apparatus may include a processor and a non-transitory computer readable medium that the processor may execute to determine whether a token is to be printed printed onto the medium, following printing onto the medium in a printing system, cause a scan bar in a media feed path of the printing system to capture an image of the printed medium. The processor may also determine, from the captured image of the printed medium, whether the token was properly printed onto the printed medium and, based on a determination that the token was not properly printed onto the printed medium, output an indication and/or an instruction corresponding to the token being improperly printed.

Abstract: In some examples, a print cartridge includes a memory device comprising quantized coefficients derived from a lossy compression, at a selected step size, of a difference color table including a plurality of difference nodes in which each difference node represents a difference value that is a difference of a value of a node of a color table and a value of a corresponding node of a reference table, the quantized coefficients useable to produce a reconstructed difference color table including a first set of difference nodes each representing a difference value that is within an error threshold at the selected step size, and a second set of difference nodes each representing a difference value that is outside an error threshold at the selected step size. The memory device further comprises corrective information to correct the second set of difference nodes of the reconstructed difference color table.

Abstract: Example implementations relate to audio samples to detect device anomalies. For example, computing device, comprising: a processing resource and a non-transitory computer readable medium storing instructions executable by the processing resource to: generate a matrix of audio information for a plurality of audio samples of a device, select audio information from one of the plurality of audio samples, generate a plurality of principal components for the selected audio information utilizing a principal component expansion, select a principal component from the plurality of principal components based on a quantity of variance, and detect an anomaly of the device based on a comparison between a real time audio sample of the device and the selected principal component.

Abstract: A user device constructs a custom color table for an imaging device and transmits the custom color table to a computing device. The computing device digitally signs the custom color table constructed at the user device. The digitally signed custom color table is deployed to the imaging device. The imaging device processes an image using the using the digitally signed custom color table.

Abstract: An example of a computer-readable medium storing machine-readable instructions. When executed, the machine-readable instructions may cause a processor to control a laser to print a test pattern. The test pattern may be scanned to determine visibility of pixels. The power of a laser may be adjusted based on the visibilities to print a security pixel.
