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.
Claims15
A system comprising:
- a pixel tone determination engine to determine, based on a preliminary rendering of print data, resulting pixel tones within each printing material separation of a plurality of printing material separations, wherein a printing material separation represents a printing material plane of the preliminary rendering;
- a tone classification engine to classify, based on the pixel tones, a tone of each object of a plurality of objects of the preliminary rendering by comparing the tone of each object to a tone threshold, wherein an object includes a plurality of adjacently disposed pixels;
- a print mode selection engine to select a specified print mode of a plurality of print modes to meet the classification of the tone of each object;
- and
- a print engine to:
- generate raster data based at least in part on a further rendering of the print data;
- and
- generate further print data including the raster data and the specified print mode.
A method for print mode quality selection comprising:
- determining, based on a preliminary rendering of print data, resulting pixel tones within specified printing material separations of a plurality of printing material separations, wherein
- a printing material separation represents a printing material plane of the preliminary rendering, and
- the specified printing material separations represent printing material separations that include a predetermined impact on a pixel tone;
- classifying, based on the pixel tones, a tone of each object of a plurality of objects of the preliminary rendering by comparing the tone of each object to a tone threshold, wherein an object includes a plurality of adjacently disposed pixels;
- selecting, by a processor, a specified print mode of a plurality of print modes to meet the classification of the tone of each object;
- 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 the specified print mode.
A non-transitory computer readable medium having stored thereon machine readable instructions to provide print mode quality selection, the machine readable instructions, when executed, cause a processor to:
- determine, based on a preliminary rendering of print data, resulting pixel tones within each printing material separation of a plurality of printing material separations, wherein a printing material separation represents a printing material plane of the preliminary rendering;
- classify, based on the pixel tones, a maximum tone of each pixel of the preliminary rendering by
- determining whether the maximum tone of a pixel is less than a tone threshold, and
- in response to a determination that the maximum tone of the pixel is less than the tone threshold, classifying the pixel as including a specified tone;
- select a specified print mode of a plurality of print modes to meet the classification of the maximum tone of each pixel;
- generate raster data based at least in part on a further rendering of the print data;
- and
- generate further print data including the raster data and the specified print mode.
