Abstract: Color conversion attempt to reproduce an input CMYK combination on a print media using an output CMYK combination. In a 2-step process, ICC profiles are used for the color conversion. In some instances, a 1-step process may be used that avoids the use of the ICC profiles and provides a faster processing time. A color progression checker determines whether the 1-step process may be used for color conversions based on standard deviations of the colorants along paths within a three-dimensional look-up table for a destination ICC profile. If a certain number of standard deviations exceed 20%, then the 1-step process for color conversion may not be effective.

Abstract: A device such as a color printer includes a main memory, a cache memory, and a convolutional neural network configured to convert pixels from a first color space to a second color space. The convolutional neural network is organized into execution-separable layers, and loaded one or more layer at a time (depending on cache size) from the main memory to the cache memory, whereby the pixels are processed through each of the layers in the cache memory, and layers that have completed processing are evicted to make room for caching next layer(s) of the network.

Abstract: A color printing system uses color printing management tiers to control color printing resources at a printing device. The color printing management tiers include a media type color management tier, an ink limited calibration tier, and a calibration and ICC profile creation tier. A print job includes a parameter that is used to select the management tier for color conversion operations for the print job. The parameter can include an attribute or a media type for the print job. The applicable tone reproduction curve (TRC) or ICC profile is retrieved according to the selected management tier. The TRC or ICC profile is adjusted according to an input applicable to the respective management tier. The TRC or ICC profile also is selected from a plurality of TRCs or ICC profiles, respectively.

Abstract: A color management system for a printing system includes a color management service that controls quality control operations, such as calibration and quality checks, over a plurality of printing devices. The color management service generates a target print job having a quality control target made of color patches. The color management service also encodes metadata within the target print job using a control strip. The control strip encodes the metadata using different color patches and color intensities. The control strip is scanned at the printing device to decode the metadata and enable a user interface to complete the quality control operation.

Abstract: A method for determining a color profile from received raster data and printing the raster data is provided. Color profiles provide a mapping from a color space of the raster data to a color space of the printer, which typically uses CMYK toner or ink. A text color profile may be employed to print crisper text, or a photo color profile may be employed to produce better images. The raster data includes a plurality of raster scan lines containing digital pixel values. The method includes determining a number of sequentially repeated digital pixel values and a number of sequentially non-repeated digital pixel values for the plurality of raster scan lines. A color profile is selected based on a determination between the repeated and non-repeated digital pixel values. An example image forming apparatus that may carry out the method is also provided.
