Paper Abstract

Tests were performed to determine the color characteristics that would permit the information contained on labels placed on x-ray films to be captured by laser scanner film digitization and by ultraviolet light film copying. Tests of laser film digitization demonstrated that the colors allowing transmission of the He-Ne laser beam were red, orange, pink, yellow, and white. The ink colors absorbing the He-Ne laser beam were green, blue, and black. Labels on films should be placed in areas of the film that are clear or lightly exposed. Experiments performed to determine the label requirements for film copying demonstrated that white, clear and pink labels transmitted the ultraviolet light used in our film copier and thus proved to be good background colors for the paper. Black and green ink and black crayon were the most opaque colors and would therefore prove to be the best lettering colors. Because of the relatively low intensity of the ultraviolet light source, the paper stock used for these labels should be relatively thin and should be placed on areas of the film that are clear or lightly exposed.
