Film Scanning Options For Your Business
Microfilm Scanning
16 mm or 35 mm film to motion picture standard is used, usually unperforated. Roll microfilm is stored on open reels or put into cassettes. The standard lengths for using roll film is 30.48 m (100 ft) for 35mm rolls, and 100 ft, 130 ft and 215 feet for 16mm rolls.
One roll of 35 mm film may carry 600 images of large engineering drawings or 800 images of broadsheet newspaper pages. 16 mm film may carry 2,400 images of letter sized images as a single stream of micro images along the film set so that lines of text are parallel to the sides of the film or 10,000 small documents, perhaps cheques or betting slips, with both sides of the originals set side by side on the film.
Aperture Cards
Aperture cards are Hollerith cards into which a hole has been cut. A 35 mm microfilm chip is mounted in the hole inside of a clear plastic sleeve, or secured over the aperture by an adhesive tape. They are used for engineering drawings, for all engineering disciplines. There are libraries of these containing over 3 million cards. Aperture cards may be stored in drawers or in freestanding rotary units.
Microfiche Scanning
A microfiche is a sheet of flat film, 105 x 148 mm in size, the same size as the international standard for paper size ISO A6. It carries a matrix of micro images. All microfiche are read with their text parallel to the long side of the fiche. Frames may be landscape or portrait in orientation. Along the top of the fiche a title may be recorded for visual identification.
The most commonly used format is a portrait image of about 10 x 14 mm. Office-size papers or magazine pages require a reduction of 24 or 25 in size. Microfiche are stored in open-top envelopes which are put in drawers or boxes as file cards, or fitted into pockets in purpose-made books.
Using specialist high resolution microfilm scanners coupled with our experienced operators we can digitally reproduce all microfilm formats to various output types (generally pdf) using our true dpi. High resolution Imaging technology allowing fast access to information with or without OCR search capability applied to the digital files. Indexing can be tailored to a customers individual requirement be it microfiche header strip information through to bespoke data entry at document level if required.
