Practical issues in color inkjet halftoning

Even Toned Screening has evolved from a research project into a practical module for halftoning on color inkjet printers, with many commercial and free software users worldwide. Feedback from these users has motivated tuning and other modifications to make the algorithm more practical. This paper discusses both the core algorithms and the practical issues involved in driving real printers for real users. The specific issues include: Nonsquare aspect ratios, Interaction between dither microstructure and weaving patterns, multilevel dot generation, processing speed, and interactions between microstructures in overlapping planes.
