STORAGE AND HANDLING
Store unexposed material at 13°C (55°F) or lower in the
original sealed package. High temperatures or high humidity
may produce unwanted quality changes.
To avoid moisture condensation on material that has been
refrigerated, allow it to completely warm up to room
temperature before opening the package. For best results,
remove the material 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 material you
need, re-wrap the package and reseal it with tape to restore
the moisture barrier.
Handle these materials very carefully by the edges to
avoid creases and fingerprints. The materials are extremely
sensitive to light; store and transport them in lighttight
boxes.
DARKROOM RECOMMENDATIONS
Do not use a safelight; handle unprocessed material in total
darkness. Be sure that your darkroom is lighttight. Eliminate
stray light from the enlarger head, repro camera lamps,
timers, digital displays, etc.; even indicator lights and
fluorescent tape can fog the material.

EXPOSURE
Expose the material from originals such as continuous-tone
or printed matter, maps, drawings, layouts, or documents in
a process or repro camera by using subtractive,
tricolor-additive, or semi-additive methods. Although this
material is balanced for exposure with a light source of 3000
to 3200 K, you can use any of the following light sources:
pulsed xenon, incandescent, halogen, or flood lamps.
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 only 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 material during exposure.
Follow these procedures to control flare:
• Keep the lenses, 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.
