Abstract
In examples, a method includes receiving print image data representing an image to be printed and selectively modifying at least one of an initial background print agent color plane and an initial image print agent color plane to determine a modified color plane.
Claims20
A method comprising:
- receiving, at a processor, print image data representing an image to be printed,
- identifying, by a processor and from the print image data, a coincident edge region in an initial background print agent color plane specifying an intended placement of background print agent and an initial image print agent color plane specifying an intended placement of an image print agent, wherein the coincident edge region is an edge in an area to be printed with both the background print agent and the image print agent;
- and
- selectively modifying, by a processor, at least one of the initial background print agent color plane and the initial image print agent color plane in a vicinity of the identified coincident edge region to determine a modified color plane.

A print apparatus comprising:
- an interface to receive image data indicative of an image to be printed on a substrate;
- a print apparatus control data module to determine print instructions for printing the image, wherein determining the print instructions comprises modifying a print agent color plane derived from the image data by at least one of:
- (i) selectively modifying at least one of a background print agent color plane and an image print agent color plane in the vicinity of a coincident edge region wherein the coincident edge region is an edge in an area to be printed with both the background print agent and the image print agent;
- and
- (ii) selectively eroding edges in an initial background print agent color plane to determine a modified background print agent color plane such that a local region of background print agent that will be less than a threshold size following the erosion is excluded from the erosion;
- and
- a print agent applicator apparatus to apply print agent to the substrate according to the print instructions.

A method comprising:
- receiving, at a processor, print image data representing an image to be printed,
- determining, by a processor and from the print image data, an initial background print agent color plane specifying an intended placement of background print agent;
- and
- selectively eroding, by a processor, edges in the initial background print agent color plane to determine a modified background print agent color plane, wherein selectively eroding the edges comprises determining whether there is a local region of background print agent that will be less than a threshold size following the erosion and, if at least one such region is identified, excluding the identified local region from the pixel erosion operation.
