Abstract

Three high-resolution digital photographic printers based on different technologies have recently been designed and fabricated by the Photographic Research Laboratories of Easiman Kodak Company. All three printers were designed to produce continuous-tone pictorial color output of high quality using conventional photographic silver halide media (paper and film). Comparison of achieved spatial frequency response dynamic range colorimetric integrity and exposure energetics will be made for a CRTbased marking engine for printing on photographic paper a laserbased marking engine for printing on photographic paper or film and a PLZT light valve-based marking engine for exposing on film. Technological constraints inherent to the printers will be discussed and a comparison of price/performance attributes for the implementations will be made. 1. DEVICE DESCRIPTIONS 1. 1. CRT A high-resolution cathode ray tube is used as the exposure device in a digital printer breadboard capable of producing 3R (3. 5" x 5" ) and 4R (4" x 6" ) on roll photographic paper (Figure 1). The printer''s roll handling capability allows for a semi-automatic mode of operation with minimum operator intervention. Image resolution is 2000 pixels by 3000 lines over an active picture area of 4. 3" x 6. 4" resulting in a pixel pitch of 54 . t at the tube face. The spot profile of the 9" flat-face CRT used approximates a Gaussian shape with a measured diameter (FWHM) of 70 j. t at a
