Initial conversion to this paper from KODAK
PROFESSIONAL Color Metallic Paper involves
rebalancing your printers. Since the green speed is about a
1/2 stop faster than Color Metallic Paper, increase your
magenta filtration by approximately 15CC.
5. Remove neutral density from your filter pack. For
example, if you determine that a filter pack of
40R + 10Y + 10C will give you a pleasing print:
a. Convert any primary filters (R, G, B) to their
subtractive equivalents (C, M, Y):
40R = 40M + 40Y.
White-Light Exposure Method
b. Add filters of the same color: 10Y + 40Y = 50Y.
Control color balance with dichroic filters built into the
printer or enlarger, or with KODAK Color Printing (CP)
Filters (Acetate) placed between the lamp and the negative.
You can use any number of filters between the light source
and the negative. If you use cyan filtration, use filters with
the suffix “-2,” (e.g. “CP10C-2”).
c. If the new filter pack has all three subtractive colors,
cancel the neutral density by subtracting the
smallest density value from all three densities:

2. Evaluate the test print under light of the same color and
brightness that you will use to display the final print.
(See “Viewing.”)
6. Adjust the exposure for the new filter pack. An
exposure time that produced a print of satisfactory
density may not produce an acceptable density when
you change the filter pack. The following table gives
filter factors for calculating exposure adjustments when
you use KODAK Color Printing (CP) Filters.
3. Judge print density first. If necessary, make another
print by adjusting the exposure as recommended in the

To use the factors, divide the old exposure time by the
factor for any filter you remove. If you add a filter, multiply
the time by the factor. If you add or remove two or more
filters, multiply the individual factors and use the result as
your factor. You may need to modify these factors for your
equipment.
Magenta + Cyan
(Blue)
When you adjust the filtration in equipment that has
built-in dichroic filters, any noticeable differences in density
KODAK PROFESSIONAL ENDURA Metallic Paper • E-4028

are due to differences in the color density of the print. For
example, you have a print with acceptable density, but a
magenta balance. When you add magenta filtration to correct
the color balance, the print will become too light, so you
must use a longer exposure time.
A rule of thumb for magenta dichroic filtration is to
change the exposure time by one percent for every unit of
change in filtration. For example, if you increase the
magenta filtration by 20M, increase the exposure time by
20 percent. Changes in yellow dichroic filtration do not
usually affect the apparent print density. If you use cyan
dichroic filtration, use the filter factors in the table above as
starting points for adjusting exposure.
LATENT-IMAGE KEEPING
Under normal conditions, you should not notice shifts in the
latent image with keeping times from 5 seconds 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, minimize them by keeping the interval between
exposure and processing as consistent as possible.)
PROCESSING
Use KODAK EKTACOLOR RA Chemicals for Process
RA-4, and use KODAK PROFESSIONAL Pro Srips Color
Negative Paper Control Strips for Process RA-4 (see
"Process Control").
Tricolor Exposure Method
Use KODAK WRATTEN Gelatin Filters No. 25 (red),
No. 99 (green), and No. 47B (blue) to give the paper three
separate exposures. Do not move the paper or the enlarger
until you have made all three exposures. Typical exposure
times for making an enlargement from a normally exposed
negative are given in the table below.
When fully converted to this paper, your developer
replenishment rate should be approximately 10% lower than
with KODAK PROFESSIONAL PORTRA III and SUPRA
III Papers or KODAK PROFESSIONAL Color Metallic
Paper. Review your process control charts and make
adjustments as needed to stay in control.
Bleach-fix replenishment rates will stay the same for
Process RA-4. When using KODAK EKTACOLOR PRIME
Bleach-Fix Replenisher, replenishment rates will need to
increase.

PROCESS CONTROL
ILLUMINATION FOR EVALUATION OF
PRINTS
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.
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.
For more information, see KODAK Publication No.
CIS-202, Using KODAK PROFESSIONAL Pro Strips
Color Negative Paper Control Strips / for Process RA-4.
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.
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.
