D-45 2
Features and Benefits
• High contrast
• Extremely fine granularity
• Ultra-high resolving power
• Very slow speed
• Optimum sensitization for helium-neon
lasers (633 nm) for character exposure and
filtered tungsten source for forms overlay
• Blue-tinted 4 mil Estar Base of 0.1 nominal
visual density
• The sensitized layer of this film contains
an organic silver compound and an
incorporated developing agent
• When properly handled and stored,
information on this film can be retrieved
for at least 100 years
• Meets requirements of ANSI/NAPM
IT9.19-1994 for thermally processed
silver microfilms
• Reformulated emulsion layer
Improved image tone, resulting in blacker
characters; reduces post-process print-up;
improves raw stock keeping, resulting in
invariant speed; improves halation protection
• New conductive antistat layer and
copolymer backing
Reduces dirt attraction, resulting in cleaner
dupes; improves transport and handling;
lowers duplicator exposure time, increasing
productivity; reduces Newton's Rings on
dupes; patented technology
• Improved overcoat
Improves overcoat adhesion on processed
fiche; patented technology

Handling
Film not in cartridges should be handled in total
darkness. Unexposed film in its cartridge can be
handled in room light.
Storage
Store unopened packages of film at 21°C (70°F).
If storage for longer than three months is
needed, 13°C (55°F) or lower is recommended.
Keep the film at 50% relative humidity or below,
and protected from radiation and X-rays. To
avoid moisture condensation on the film, cold
or frozen film should be warmed throughout to
approximate room temperature before the
package is opened, six hours if refrigerated, or
overnight if frozen. Once a package is opened,
do not refrigerate or freeze the film. If the Kodak
Komstar Microimage Processor will be shut
down for four hours or more, unthread the film
from the film transport.
Image Structure
Resolving power: (based on recommended
process)
Test-Object Contrast 1000:1 (ISO-RP)
1000 lines/mm
These values were determined by a method
similar to the one described in ISO Standard
6328-1982 “Photography—Photographic
Materials—Determination of ISO Resolving
Power.”
Diffuse RMS granularity: 15
Read at a net diffuse density of 1.00 (with a
Kodak Wratten Gelatin Filter No. 47B) using a
48-micrometer aperture.
