Determining print modes of print apparatuses

An apparatus comprising:

• a processor to:
• receive image data representing an image to be printed using a print apparatus;
• identify, based on the image data, a color block of a first color in the image, the color block having an area that exceeds a defined threshold area;
• determine, based on the image data, a proportion of each of a plurality of colors of print agent to be used to print the first color;
• and
• determine, based on the determined proportions of print agent of the plurality of colors, a print mode from a plurality of print modes to be used by the print apparatus to print the image, the print mode indicating a number of passes to be used by the print apparatus to print the image, wherein the number of passes corresponds to a greatest number of passes with a least amount of perceptible banding.

A non-transitory machine-readable medium comprising instructions which, when executed by a processor, cause the processor to:

• identify, from data representing an image to be printed using a print apparatus, a first color fill region having an area that exceeds a defined threshold area, wherein the first color fill area is to be printed in a first color;
• determine, from the data, a proportion of print agent of each of a plurality of colors to be used to print the first color;
• and
• determine, based on the determined proportions of print agent, printing parameters to be applied to the print apparatus to print the image, the printing parameters including an indication of a number of passes to print the image, wherein the number of passes to be used by the print apparatus corresponding to a greatest number of passes with a least amount of perceptible banding.

A print mode determination method, comprising:

• receiving, using a processor, image data defining parameters of pixels of an image to be printed using a print apparatus;
• identifying, using a processor and based on the image data, a first fill area in the image that exceeds a defined threshold area, wherein the first fill area is to be printed in a first color;
• determining, using a processor and based on the image data, a first proportion of print agent of each of a plurality of colors to be used to print the first color;
• and
• determining, using a processor and based on the determined first proportions of print agent of the plurality of colors, a print mode from a plurality of print modes to be used by the print apparatus to print the image, the print mode indicating a number of passes to be used by the print apparatus to print the image, wherein the method further comprises:
• determining, based on the image data, a geometrical distribution of pixels within the first fill area;
• and
• responsive to determining that the geometric distribution of pixels within the first fill area meets a defined criterion, determining the print mode further based on the determined geometrical distribution of pixels within the first fill area, wherein the defined criterion corresponds to whether the geometrical distribution of pixels has at least one of a width, thickness, or height greater than a corresponding defined threshold.
