According to examples, multi-color printing may include generating, based on an analysis of a print job image, a plurality of contone planes that represent the print job image. Multi-color printing may further include generating, based on an analysis of two or more sets of the contone planes determined from the plurality of contone planes, two or more corresponding sets of halftone planes and a fixer plane for each set of the halftone planes. Multi-color printing may further include generating, based on an analysis of the fixer plane for each set of the halftone planes, a combined fixer plane, and generating, based on an analysis of the two or more corresponding sets of halftone planes and the combined fixer plane, print data to print the print job image.
