A method for forming an image by a print device includes: 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. The method further includes identifying a neighboring pixel within a region of the image around the first pixel, the neighboring pixel corresponding to a functioning inkjet. The method further includes 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. The method further includes causing the functioning inkjet to eject an ink drop based on the modified halftone value for the neighboring pixel.
