Color printing is a modern technological wonder that appeals to an impressive sensory ability: human vision. Colorful images influence what we buy, how we dress and the decisions we make on a host of other life‐style issues. Digital color printing provides ease of control and the potential for repeatable, WYSIWYG—"what you see is what you get"—printing. Analog color printing does not permit a comparable level of editing and control, and only in the hands of craftspeople does it provide repeatable results. Digital color printing transfers image control from the chemical tank to the computer. (See figure 1.) Furthermore, personal computers have increased so much in speed, memory and computing power that processing requirements deemed virtually impossible to satisfy only ten years ago are now met routinely. The emergence of digital (or electronic) photography will bring new and exciting capabilities to users and allow us to optimize the preparation of information.
