Kodak D-45 manual Features and Benefits, Physical Properties before-process, Handling, Storage

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

Physical Properties (before-process)

Nominal Thickness Data

Unprocessed Film

Base	4.0 mil
Emulsion	0.5 mil*
Total	4.5 mil

*blue-tinted, Estar Base; backing: antistat layer and copolymer topcoat—negligible

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—PhotographicMaterials—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.
