Microfilm is as a very small black and white photographic negative image of a document—a paper or digital document.In fact, the original method of making microfilm was very similar to taking a photograph of a still image; in the case of microfilm, the still image was a piece of paper that contained handwritten, drawn or typewritten information. Through the optics of a camera, the size of the image was reduced to film. Initially this film was 105mm by 135mm. Later, film with smaller size widths such as 16mm and 35mm were developed.
The most up-to-date method for creating microfilm is very different than previous processes. Today, microfilm creation is similar to making a paper print with an LED digital plain paper printer.
Digital printers create rows of dots (pixels) on an LED light bar that are exposed to an imaging drum. The imaging drum transfers the dots to the paper as it moves past the imaging drum.
In the same way, microfilm images of digitally created documents or scanned documents are created using a recording device (a 16mm or 35mm Archive Writer) that exposes the film to a row of pixels using a high-resolution LED light bar, combined with precision reduction optics as the film moves past the LED light bar.
- It’s the most economical way to archive business or government records and comply with records management laws and mandates.
- Preserve and secure records on media that will last more than 500 years.
- Eliminate worries about data loss, migration issues, manmade and natural disasters.
- With 35mm microfilm get true, readable images from document sizes greater than 17″ x 22″ (A2).
Microfilm is the most trusted form of document preservation for critical information among manufacturers, utilities and government agencies – where documents must be kept for decades and even centuries in some cases.
It’s an important records management strategy for some of the most trusted and secure companies, organisations and corporations in the world.
