Abstract
There are four sub-systems in the digital printer. These sub-systems have the following functions: 1. Optical scanning of a document, and conversion of the data to electric signals. 2. Supplying power to heating elements. 3. Formation of images on a thermo-plastic resin film by puncturing using heat. 4. Supplying ink to the punched portions to form images. This paper shows the application of Quality Engineering on the optimization of ink prescription for the fourth module of digital printer. ln the fourth module, the pattern on the stencil paper for platemaking is transcribed to an image pattern. Such results were analyzed and then evaluated.
