PROCESSING
Use KODAK EKTACOLOR RA Chemicals for Process RA-4,
and use KODAK PROFESSIONAL Pro Strips Color Negative
Paper Control Strips / for Process RA-4. (See "Process
Control.")
Note: Although Kodak does not recommend Process
RA-2SM for professional media, some customers may
judge the results acceptable for certain applications.
Customers should test the media to determine
acceptability, as this process may provide warmer results
than desired.
For detailed information on replenishment rates and
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/photochemicalpubs.
Do not use drying temperatures above 93°C (200°F) to
avoid damage to prints.
Underdrying can produce tackiness that tends to make
paper stick when it is wound into rolls before cutting.
Overdrying can cause curl and complicate transport in print
finishing.
Do not ferrotype this paper—its surface dries to a
natural gloss without ferrotyping.
PROCESS CONTROL
To produce high-quality color prints consistently and with
a minimum of waste, you need to match your process to a
standard for density, color, and contrast each time you
process paper. In addition to monitoring process
parameters such as solution times, temperature,
replenishment rates, solution concentrations, etc., you
should regularly run control strips to ensure best results.
KODAK PROFESSIONAL Pro Strips Color Negative
Paper Control Strips / for Process RA-4 (CAT 129 8587)
are designed specifically for use with KODAK
PROFESSIONAL Papers and KODAK PROFESSIONAL Print
and Display Materials in professional labs. These control
strips are designed to detect process conditions that can
degrade the quality of your finished prints. They are better
able to track the papers that are processed in professional
finishing laboratories.

No. Z-130, Using KODAK EKTACOLOR RA Chemicals,
section 7a.

ILLUMINATION FOR EVALUATION OF
PRINTS
Evaluation of prints for color and density requires higher
illumination levels than those used in normal display
conditions. A good average conditionfor evaluation is a
light source with a color temperature of 5000 K ± 1000, a
Color Rendering Index of 85 to 100, and an illuminance of
at least 50 footcandles (538 lux). Fluorescent lamps such
as cool white deluxe (made by several manufacturers)
meet these conditions.
You can also use 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.
Viewing conditions should meet ANSI Standard
PH2.30-1989.
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.
POST-PROCESS TREATMENTS
Mounting Prints
You can mount prints with dry mounting tissue. The
temperature across the heating platen should be 82 to
93°C (180 to 200°F). Preheat the cover sheet that you use
over the face of the print to remove moisture. Apply
pressure for 30 seconds, or up to 3 minutes in the case of a
thick mount.
Temperatures above 93°C (200°F) for long periods of
time may cause physical and color changes in prints.
Excessive moisture may also cause color shifts. Mounting
at the lowest temperature at the shortest time will reduce
these changes.
You can also use a contact-type adhesive or cement for
cold-mounting.
For information on lacquering and other post-process
treatments, see KODAK Publication No. E-176,
Post-Processing Treatment of Color Prints—Effects on Image
Stability.
