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.

SCANNER TOOLS
The KODAK Q-60 Color Input Targets are available on
KODAK EKTACHROME Professional Film in both 35 mm
and 4 x 5 inch formats and on KODAK EKTACOLOR Paper.
Developed primarily for use by prepress houses in the
printing industry, this target can also be used by professional
photographers, desktop publishers, and in the emerging
hybrid imaging area.
The target is designed for use in the commercial and
desktop arenas as a comparative control tool to help
customers calibrate their input product to the final output.
This target maps the gamut of color space that KODAK
EKTACHROME Film and EKTACOLOR Paper can
reproduce.
When used properly, customers will be able to compare
their output—whether it is separations for the printed page
and four-color printing, or second-generation originals from
a film recorder to the originals. This will help customers
optimize the capabilities of their system for color
reproduction of an extreme range of color gamut.
Scanner color characterization targets produced in
accordance with ANSI IT8.7/1 (transmission) and IT8.7/2
(reflection) Standards (or ISO 12641) are available from
Kodak.
The KODAK PROFESSIONAL Q-60 Color Input
Target
⁄
Q-60R2 is manufactured on KODAK
PROFESSIONAL ENDURA Paper, and is likewise
identified by a watermark with a single grey dot under
PAPER. This target can be used with both the newer
ENDURA Papers and older papers. The older Q-60R1
target, which has the same two-dot watermark as the older
papers, can be used with the newer papers.
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 condition 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.
