LATENT-IMAGE KEEPING
This paper features improvements in the stability of the
latent image. Under normal conditions, you should not
notice shifts in the latent image with keeping times from
1 minute to 24 hours. Therefore, you do not need to change
your printing procedures to compensate for latent-image
shifts under normal temperature and handling conditions. (If
shifts do occur, you can minimize them by keeping the time
between exposure and processing the same for all paper.)
PROCESSING
Use KODAK EKTACOLOR RA Chemicals for Process
RA-4 to process this paper.
For information on processing this paper in continuous or
roller-transport processors, see KODAK Publication No.
Z-130, Using KODAK EKTACOLOR RA Chemicals. For
information on processing this paper in trays or rotary-tube
and drum processors, see KODAK Publication No. J-39,
Tray, Drum, and Rotary-Tube Processing with KODAK
EKTACOLOR RA Chemicals. Both publications are
available through our website at
www.kodak.com/go/photochemicals.
Use a drying temperature below 205°F (96°C). Do not
ferrotype this paper; the F surface dries to a natural gloss
without ferrotyping.
VIEWING
Evaluate prints under light of the same color and brightness
that you will use to view the final prints. A good average
viewing condition is a light source with a color temperature
of 5000 ± 1000 K, a Color Rendering Index (CRI) of 85 to
100, and an illuminance of at least 50 footcandles (538 lux).
Fluorescent lamps such as the cool white deluxe (made by
several manufacturers) meet these conditions. You can also
use warmer lamps such as the Phillips 5000 K Ultralume, or
a mixture of incandescent and fluorescent lamps. For each
pair of 40-watt cool white deluxe fluorescent lamps, use a
75-watt frosted tungsten bulb.
RETOUCHING
If possible, do any required retouching on color negatives
before you make prints—especially if you plan to make more
than one print from each negative. For information on
retouching negatives, see KODAK Publication No. E-71,
Retouching Color Negatives.
If the negative image is small, you can make corrections
much more easily by applying dry or liquid dyes to small or
large areas of the enlarged print. Although you’ll probably
do most retouching with dyes, you may sometimes want to
use black lead, colored pencils, or opaque. Because color
prints have separate dye layers, you can’t use an etching
knife to reduce density as you can with black-and-white
materials. For information on retouching prints, see
KODAK Publication No. E-70, Retouching Prints on
KODAK EKTACOLOR and EKTACHROME Papers.
For information on lacquering and other post-process
treatments, see KODAK Publication No. E-176,

Image Stability, available through our website at

MOUNTING
You can mount prints with KODAK Dry Mounting Tissue,
Type 2. The temperature across the heating platen of the
mounting press should be between 180 and 200°F (82 and
93°C). Temperatures above 210°F (99°C) or high pressure
may cause physical and color changes in prints. Preheat the
cover sheet that you use over the face of the print to remove
moisture. Apply pressure for 30 seconds or longer for a thick
mount.
You can also use a contact-type adhesive or cement for
cold-mounting.
DISPLAYING
Photographic dyes, like all dyes, can change with time and
exposure to sunlight, ultraviolet radiation, excessive heat,
and high humidity. To help prevent changes in photograph ic
dyes, follow these guidelines:
•Illuminate prints with tungsten light whenever possible.
•Display prints in the lowest light level consistent with
your viewing needs.
•If a print is exposed to direct or indirect sunlight or
fluorescent light, use an ultraviolet-absorbing filter
(such as glass) between the light source and the print.
•Keep the temperature and humidity as low as possible.
