What is microfilm?

microfilms

Microfilming is basically a photographic process of copying documents onto film at a reduced size. It is a way of saving 96% of file storage space, having a legally admissible record of your documents which will, properly stored last over 500 years.

Tell me a little more

Documents and files containing mostly A4 and A3 pages can be filmed very economically using 16mm film, whilst drawings, plans and maps of almost any reasonable size can be captured onto 35mm film. It may sound like an unusual exercise, but a large number of companies are now choosing to use microfilm as a backup or deep archive media to protect their most valuable electronic documents. There are a number of reasons why one might chose to do this, not least of which is the current pace of technological advance, which threatens to make software and file formats redundant after only a very short life cycle.

Can microfilm and digital live together?

Microfilm is the perfect solution for long-term archiving. As well as its longevity, it is legally admissible. However, it does not have the accessibility of imaging systems and cannot be considered viable when rapid, multi-user access is necessary. As a result, many projects overlook microfilm, based on its retrieval capabilities. However microfilm is an excellent media for being digitally scanned as the microfilm image is very small, and is very quick to scan (compared to a sheet of A4 paper). The legacy from decades of producing microfilm is that many documents archived fifty years ago are still readable today and can be easily digitised if required. With microfilm there are no concerns about platform changes, software upgrades and viruses

What we can offer

Micrographic Applications meets or exceeds ASTM standards for archival quality microfilm. We use Kodak silver halide film, 16mm (100'), or 35mm (100'). The majority of our conversion work is done on planetary cameras to enhance image clarity, but rotary 16mm cameras are also available. We have the ability to handle various document sizes from engineering drawings to check size.

Once the documents are filmed and the films processed, they are checked for accuracy, density (optimum darkness) and line resolution.

Images can be returned as roll film or they can be loaded into jackets or aperture cards for ease of use
