Why Microfilming?
Services & Software / Why Microfilming?
There are various reasons to consider for the creation of microfilm.
  1. Low cost, reliable, long-term standardized image storage medium. If stored properly, the medium has a life expectancy of hundreds of years.
  2. Current microfilm is of a format (cellulose nitrate/acetate) that is deteriorating to a point where it requires duplication.
  3. Certain industries must retain documents that are critical to their business for anywhere from 10 to 100 years.
  4. Paper beginning to deteriorate
  5. Save space within your facility
  6. Permanently archive them in a durable, easily accessible (through light and magnification) format
In 1947, we established one of the first microfiche imaging production facility in the United States, making the new imaging method widely available for the first time. Ever since, Northern Micrographics has specialized in developing new solutions for both preservation and access.

All Northern Micrographics procedures and processes will adhere to current ANSI, AIIM, RLG and United States Newspaper Program standards. Equipment is checked daily in accordance with ANSI/AIIM standards. Our production facility contains an ANSI-standard storage vault that is fireproof, waterproof, and temperature/humidity controlled conforming to the ANSI/NAPM IT9.11 storage standard. All microfilm masters are stored in our vault for safe keeping as well as work-in-process source documents.

NM uses industry standard 16mm and 35mm planetary cameras with the capability to film documents ranging in size from less than 8.5” x 11” to engineering J-size roll drawings. Northern Micrographics’ deep tank processors assure sufficient wash time to eliminate residual thiosulfate and other chemicals; however, testing can be done in accordance with ANSI PH4.8-1985 and ANSI IT9.1-1992 (Polysulfide Treatment and Methylene Blue Testing).

Microfilming Procedures
  • Northern Micrographics creates high-contrast, black and white, 16mm/35mm polyester-based, silver halide microfilm masters with a LE-rating of 500 years and a minimum thickness of 4 mil (conforming to ANSI/NAPM IT9.1-1996). Each reel will include leader and trailer film of no less than two feet and no more than four feet in length. The service copy leader and trailer will not be less than 18 inches long.
  • NM will provide the appropriate resolution and uniform density targets, as well as other standard targets including Start, Density, Resolution, End of Reel and Last Reel. Other custom targets can be included as specified by the customer.
  • A duplicate negative print master will be created (as necessary) from the master film and will meet the same technical requirements as the archival master.
  • Any service copy negative will be created on silver halide film stock that will have a LE-rating of at least 100 years.
  • Storage reels, fasteners, and storage boxes conform to and meet all requirements of ISO 18902:2001, ANSI IT9.2-1998, ANSI/NAPM IT9.1-1996 and ANSI/NAPM IT9.11-1993. All spools and boxes shall be acid-free and non-corroding in nature.
Inspection and Quality Control
All camera masters receive 100% visual inspection for visual defects or missing pages and the quality control data is recorded. All inspection technicians are required to wear white, lint free gloves when handling first and second generation film. Splicing of first generation film, if required, will meet requirements.

Northern Micrographics will return camera masters separately from the negative print master and negative service copy. Once the negative print masters are approved, the camera masters and the original source documents (if required) will be shipped to the customer.

Northern Micrographics will make every effort to insure the quality of all microfilm masters and duplicates. If any products are deemed unacceptable and do not meet project specification, NM will make necessary corrections at no cost.
