Digital Halftoning

Abstract

There are extreme situations where even with the best quantization algorithms it is hard or impossible to mask quantization contours. This is the case, for example, in two-level quantization, which must be used for display on one-bit graphical output devices. Such output devices are very common: laser printers and phototypesetters are examples of them. In spite of their limitations in what concerns color reconstruction, they can be used to display grayscale images. As we will see in Chapter 11, offset color printing also reduces, via color separation, to the printing of grayscale images on one-bit devices.
