Paper Abstract

To extend the life of an original document or for convenience of handling the image, it is often desirable to make reduction copies of the document. However, current microimaging systems have not been optimized for high-quality color reproduction. This paper describes the image quality and optics considerations for high-resolution color imaging. As a result of this study, two new 105 mm fiche-size color film systems are proposed. System I is a positive-positive system, using KODAK EKTACHROME Professional Film 6118, that can be used for image reductions up to six times printed on KODAK EKTACHROME Duplicating Film 6121. The second procedure, System II, is negative-positive and offers reductions up to 10 times with excellent image quality. System II uses EASTMAN Color Intermediate II Film 5243 as a camera negative and is printed on EASTMAN Color Print Film 5384 to produce a positive transparency. Reductions higher than 10 times are possible but with a corresponding loss in image quality, which is primarily due to optics limitations. Another major concern is the maintenance of image quality from the center to the corners of the original.
