ARTWORK

Cleanliness and good contrast are important for best results. Use black ink, black crayon, black transfer letters on a white background, black letters obtained from a lettering machine, or type set by a local printer. Try to maintain an even density of black. Also make sure that the lettering or artwork meets minimum legibility requirements.

COPYING PROCEDURE

When you are making slides of lettering or artwork, a single- lens-reflex camera offers a decided advantage because you can compose and focus the image in the camera viewfinder. You may need a supplementary close-up lens or macro lens, especially if the artwork contains fine detail.

We recommend that you use a matched pair of 200 W tungsten lamps or two tungsten-halogen photolamps, in a fixed position, for illumination on the sides of the copy stand. Determine the best shutter speed and lens aperture combination for a given lighting setup and title by a trial exposure series, using the suggested exposure index (EI) as a starting point. Use EI 25 when processing in KODAK Developer D-11 and EI 8 when processing in KODAK PROFESSIONAL KODALITH Super RT Developer.

One method to determine the initial exposure time and aperture setting (f/number) for the test series is to measure the illumination on the original material. Take a direct reading with an incident-light meter, or read a gray card with a reflected light meter. You’ll find that the built-in camera light meters tend to underexpose white copy material because they average the reflected light from a wide area of the scene. However, you can use them satisfactorily with a gray card.

Another method for determining your first set of trial exposures is to set the shutter speed at 1 second and take a shot at every f-stop on the lens. Record the f-stop of the best exposure and note the lens and lighting arrangement so you can produce good results again in the future.

COLORING THE SLIDES

You can color the dry transparency by using a cotton swab to apply the dye or by dipping it in water-soluble dyes, such as KODAK Liquid Retouching Colors, CAT 190 1743, or ordinary food coloring.

An alternative to using dyes is to mount a colored filter with the slide. Theatrical gelatin filters are available in sheets in a variety of colors and shades.

OPAQUEING THE SLIDES

One of the advantages of reverse-text slides made from high- contrast black-and-white films is the high-density background, which can conveniently cover up imperfections in the background of the original artwork. If, however, any dirt, sketch lines, or other objectionable marks on the art are reproduced on the processed film, these white marks can be easily painted out with opaque, a light-blocking compound,

such as KODAK Opaque Black, CAT 146 4312. Many of the black pens and pencils sold for marking overhead projector transparencies also work well in this application.
