Abstract
Printing methods and systems are described herein. In one example, a method includes rasterizing a document to create color rasters and linearizing the color rasters to create high drop weight (HDW) planes and low drop weight (LDW) planes. HDW and LDW halftone planes are created from the HDW and LDW planes. The HDW and LDW halftone planes are masked to create HDW and LDW printhead maps, and the HDW and LDW printhead maps are merged into print data. The print data is sent to a number of printheads.
