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, a print mode to be used by the print apparatus to print the image.

A 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.
