Overview

Microforms are scaled-down reproductions of documents, typically either films or paper, made for the purposes of transmission, storage, reading, and printing. Microform images are commonly reduced to about 4% or 1⁄25 of the original document size. For special purposes, greater optical reductions may be used. Three formats are common: microfilm (reels), microfiche (flat sheets), and aperture cards. Microcards, also known as "micro-opaques", a format no longer produced, were similar to microfiche, but printed on cardboard rather than photographic film. With our DigiSmart - Document Management System Software capabilities like storage, archival, indexing, meta data and AI/ML capabilities, you can store and retrieve documents effectively.

Microfilm

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 35 mm rolls, and 100 ft, 130 ft and 215 feet for 16 mm 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 microimages 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.

Microfiche

A microfiche is a sheet of flat film, 105 × 148 mm in size, the same size as the international standard for paper size ISO A6. It carries a matrix of microimages. 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 × 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.

Microfilm Writers

Microfilm Archive Writer convert digital images in .tiff, .pdf and other formats to 16mm or 35mm microfilm. These microfilm authoring units can write images on microfilm roll at amazing speeds. Thses Microfilms can be used then for long term archival purpose.
