Paper Abstract

An experimental high-resolution digital printer has been developed that is capable of directly exposing standard color photographic paper in any of four formats ranging in size from 8 in. by 12 in. to 20 in. by 30 in. The printer utilizes three visible wavelength gas lasers to expose continuous-tone color prints in 60 seconds. Each image contains 4000 pixels by 6000 lines of 8-bit red green and blue data at corresponding pixel pitches of 500 to 200 pixels per inch. Integral optical power measurement standards maintain consistent calibration. The ability to produce artifact-free continuous-tone images over this large area requires a critical design approach in all areas of optical mechanical and electronic design. A systems level discussion will illustrate the approaches taken to meet these design challenges. The printer hardware and calibration systems will be described and their performance will be presented. Sample prints of both internally generated test patterns and image scenes will be shown at the conference but could not be suitably reproduced for these proceedings. 1.
