1. A method for forming an image by a print device, the method comprising:
identifying a first pixel in halftone image data, the halftone image data representing an image to be formed, the first pixel corresponding to a malfunctioning inkjet of a plurality of inkjets;
identifying, within a region of the image around the first pixel, a neighboring pixel, the neighboring pixel corresponding to a functioning inkjet; and
generating a modified halftone value for the neighboring pixel by:
identifying a missing color associated with the malfunctioning inkjet,
identifying a replacement color to compensate the missing color, the replacement color being a different color than the missing color, and
modifying a halftone value for the neighboring pixel based on the replacement color; and
causing the functioning inkjet to eject an ink drop based on the modified halftone value for the neighboring pixel.
