Image scanners contribute to the digitization of prepress and printing processes. Advances in computers and semiconductor CCDs and memory devices have altered the functions and performances of scanners, and the digitization of prepress and printing processes has progressed. Since 2000, computer-to-plate technology has become prevalent, and during that transition, there was a demand to digitize very high resolution still images produced on analog films. This report describes the evolution of prepress scanner technology in the prepress and printing processes.
