2 KODAK EKTACHROME RADIANCE III HC Copy Paper • E-2411
STORAGE AND HANDLING
Store unexposed paper at 13°C(55°F) or lower. High
temperatures or high humidity may produce unwanted
quality changes. To avoid moisture condensation on paper
that has been refrigerated, allow it to completely warm up to
room temperature before opening the package. For best
results, remove the paper from cold storage the day before
printing, or use the warm-up times in the following table. For
more storage information, see KODAK Publication No.
E-30, Storage and Care of KODAK Photographic
Materials — Before and After Processing.
These times are based on a single package, positioned to
allow free air circulation. After you remove the paper you
need, re-wrap the package and reseal it with tape to restore
the moisture barrier.
Handle this paper very carefully by the edges to avoid
creases and fingerprints. This high-speed paper is extremely
sensitive to light; store and transport it in lighttight boxes.
DARKROOM RECOMMENDATIONS
Do not use a safelight; handle unprocessed paper in total
darkness. Be sure that your darkroom is lighttight. Eliminate
stray light from the repro camera lamps, timers, digital
displays, etc.; even indicator lights and fluorescent tape can
fog the paper.
EXPOSURE
You can expose EKTACHROME RADIANCE III HC Copy
Paper from opaque originals in a process or repro camera by
using subtractive, tricolor-additive, or semi-additive
methods. Although this paper is balanced for exposure with
a light source of 3200 K, you can use any of the following:
pulsed xenon, incandescent, flood, or halogen lamps. Do not
use fluorescent lamps or electronic flash.
Using a Process (Repro) Camera
For a 1:1 ratio in a Klimsch Super M3 Repro Camera
equipped with a halogen light source, use these
trial-exposure conditions:

Because exposure times and filtration will differ with the
equipment, the light source, the original, your process
control, etc., use the tables as a guide.
To maintain high image quality, control flare as much as
possible. Flare consists of stray ambient light and scattered
image light that might reach the paper during exposure.
Follow these procedures to control flare:
• Keep the lens surfaces, mirrors, filters, and copyboard
glass clean and free of scratches.
• Keep the interior of the camera clean.
• Use the additive or semi-additive printing method
whenever possible to minimize the number of filters in
the optical path.
• Adjust the copyboard lights and room lights so that
neither the lights nor reflections from the copyboard
glass fall on the camera lens.
• Mask the areas surrounding the original with black
material.
Adjustment for Long or Short Exposures
You will not notice a change in the speed or in the contrast of
RADIANCE III HC Copy Paper at exposure times from
0.5 second to 100 seconds with tungsten, halogen, or
pulsed-xenon light sources. We do not recommend using
flash to expose this paper. The short flash exposure times
will affect the quality of the prints.
LATENT-IMAGE KEEPING
You should not see any shifts in the latent image with
different keeping times between exposure and processing.
Therefore, you do not need to change your printing
procedures to compensate for latent-image shifts under
normal temperature and handling conditions.
