Microfilm – Microfiche – Aperture Cards
Our microfilm scanning teams have the ability to scan all types of microfilm and microfiche. 16mm or 35mm roll film, microfiche jackets and aperture cards can easily be converted to PDF or TIFF formats.
With a greater demand for microfilm scanning our team has expanded significantly during the last five years. This means we can undertake any size job you may have whether it’s a one off bulk job or individual documents. We train our staff to the highest standard to ensure they have the knowledge to handle every aspect of microfilm scanning.
Since the 1970s companies and organisations have used microfilm to combat the need for bulky paper filing systems. However, the introduction of electronic scanning saw a shift in preference, microfilm of all types can be difficult to view, print or retrieve from. More organisations are now looking at microfilm scanning as a way to ensure continued compliance and disaster recovery. It also means you can free up valuable space in your work place.
Identifying your micro form images
Microfilm Reel or Roll Film 16mm/35mm
16mm Microfilm will often be in a small box (usually black) or in a hard case (often buff in colour), each 16mm reel can hold up to 2500 images, 16mm film holds original documents which were A3 or below, a master film will be grey/black in colour and a copy film will be deep blue which is commonly known as a diazo. Scanning the master film will always give you the best result, but both can be scanned. 35mm Microfilm will also be found in a black box with a flip lid it would have been used to film any image over A3 in size and again the master would be grey/black whilst the copy would be deep blue in colour.
Microfilm jackets / Microfiche 16mm/35mm
Microfilm jackets are generally 6 x 4 in size and contain microfilm images in rows, (known as channels) a 16mm jacket will have capacity for 5 rows and a 2 channel jacket which holds 35mm film will have two rows. Each jacket will have a strip across the top which will have been indexed by the original file/folder information – it may also say 1 of 3, 2 of 3 etc which indicates the size of the original file exceeded one jacket and was continued across a number in the same sequence as the original paper record.
The colours of the film will mirror that of roll film (see above) and again the better images are generally reproduced from the master.
It was also possible to microfilm in colour, and although rare this can be reproduced when scanning the original microfiche or film
Combination jackets/ Combination fiche
Combination jackets are made up of both A4 images (16mm) and over A3 images (35mm) and have one channel which holds the 35mm images and three channels which hold the 16mm images. They were most commonly used for planning applications, building control files and project files. Typically the combination jackets forms the first part of the file, whilst the remaining microfilmed images are housed in two channel (35mm) or five channel jackets (16mm) and will hold the 1 of 5, 2 of 5, 3 of 5 indicators – this was done to minimise the amount of jackets used to complete a full file. Once scanned in sequence your electronic images will mirror the original file.
Aperture cards are used for single drawings and are typically 6 inches in length. Each card will be indexed by the drawing number sometimes including the sheet number, revision number etc, however, some also have punch holes which indicate information relating to the drawing held on each card. These aperture cards can be scanned and indexed from either the card or the original drawing or plan contained on each.
Computer output microfilm (COM)
Computer output microfilm or COM was produced in the early days of computers, when storage space was expensive so information which needed to be retained was downloaded onto computer files and transferred to com fiche or com rolls each roll would hold circa 5000 images and each fiche 278 images.
Microfilm reader printers became expensive to buy or maintain and their availability has reduced significantly. The use of effective microfilm scanning services brings new life to archive microfilm records and removes the issues now associated with a microfilm legacy.
In certain instances when the microfilm is of a good quality the use of OCR technology can also be applied bringing a significant increase in accessibility of information from your microfilm library. Many clients have described the electronic image from microfilm as being significantly better in quality, clarity and integrity.
