Paper Abstract

The Tektronix CFOT was used to expose Mead Cycolor and 3M dry silver photosensitive media. The results are presented and compared. The color gamut time to complete exposure and discernible resolution for the media are compared. Reciprocity failure and methods of minimizing the problems associated with it are discussed. The interactions between reciprocity failure and exposure time are discussed. The color coordinates attainable on the exposed media were determined by adjusting the paper feed speed and the intensity of the CFOT to obtain a range of exposures up to and beyond complete exposure. The CIELa*b* color coordinates of the media were measured with a Minolta color meter (Chroma Meter II). The discernible resolution was measured by exposing a 32 x 32 dot matrix on the media and then shrinking the dot to dot spacing between subsequent exposures to obtain a range of dot to dot spacings corresponding to resolutions ranging from 150 to 300 DPI. The exposed media was then examined under magnification to determine where uniform color fill was achieved. 1. CATHODE RAY TUBE DESCRIPTION The CFOT is a line scan tube with a fiber optic faceplate designed for producing full color hard copy on optically sensitive media. The tube has 3 stripes of phosphor each approximately . 060 inches wide by 8 inches long. The three phosphors are red green and blue enabling full color hard copy by sequentially
