  • CLASSIFICATION BASED PRINTING MATERIAL SET SELECTION
    Publication number: 20220036147
    Abstract: In some examples, classification based printing material set selection may include analyzing a preliminary rendering. Classification based printing material set selection may further include generating raster data based at least in part on a further rendering of the print data, and generating further print data including the raster data.
    Type: Application

  • PRINT MODE QUALITY SELECTION
    Publication number: 20210279534
    Abstract: In some examples, print mode quality selection may include determining, based on a preliminary rendering of print data, resulting pixel tones. Print mode quality selection may further include generating raster data based at least in part on a further rendering of the print data, and generating further print data including the raster data and a specified print mode.

  • Print saturation calibration
    Patent number: 10124598
    Abstract: Examples include computing devices, processes, and/or machine-readable storage mediums comprising instructions to analyze at least one digital image corresponding to calibration output of a printing device to determine location saturation values for nozzle locations of the printing device. At least one printhead is segmented into segments corresponding to one or more nozzle locations. A reference segment is determined from among the segments of the printhead, and a uniformity correction value is determined for at least one segment based at least in part on the reference segment.
