Microfilm is the safest, most secure way to protect your documents.
What is Microfilm? This is a common question that we receive from web inquires. This blog provides background about microfilm and its application in a digital world.
Microfilm is similar to things to which you are already very familiar such as photographs and paper documents.
First, think of microfilm 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 105 mm by 135 mm. Later, film with smaller size widths such as 16 mm and 35 mm were developed.
Second, think of microfilm as an analog image of a document similar to a document on paper. Microfilm is an image that is readable by the human eye with the aid of a magnifying glass. This is in contrast to a digital image which is made up of digital bytes that are only readable by a computing machine with the appropriate interpreting software.
Microfilm Creation Today
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 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.
Please note that microfilm and paper documents are similar; they are analog renderings of documents that are eye readable and are created using similar processes. Also, the cost to produce paper documents and microfilm documents is essentially equivalent.
