This chapter aims to introduce the topic of digital color halftones. It focuses on color halftones for printed material, with an emphasis on the problems and trade-offs that need to be made when choosing the type of halftoning method or structure to use for a given image or print medium. The chapter explores the different types of halftone structures and understand where and when to use which digital color halftoning technologies. It describes some of the latest efforts in this area of study in digital color halftones. The halftone grid is the visual dot pattern produced by the halftoning operation. It will be rotated for color halftone printing. Mid-resolution printers have achieved better angles and frequencies with smaller multi-center dots that were carefully hand tuned, but some visual low-frequency artifacts remain. The halftone implementation grid is made up of rectangles with the same area as the halftone grid, but it is not rotated.
