In today’s world Microfilm Scanning plays a vital role in any archival text protection and access approach. Mathenson Records Management is counted among the world’s best Microfilm Scanning Services Providers from Mumbai. Mathenson is having over 50 years of experience in working with micrographic media. At our microfilm laboratory department has transformed hundred millions of documents, newspaper, book and aperture cards into microfilm. Our well educated staff members use top & proven quality of high speed conversion equipment that is ST ViewScan III and FlexScan (types of scanners) combined with proprietary processes that can digitally convert more than 12 million images of 16mm or 35mm microfilm per month.

Microfilm conversion is a numerous pace process and it depends on the requirements of our customers and the condition of microfilm. At Mathenson, we start this process by preparing files which are converted into microfilm and then evaluate an unsystematic collection of our consumer’s film and successively going a project test to verify the possibility of work and the best methods for achieving the clients preferred conclusions.

During this counseling approach, all scanned samples are saved in a template and examples are sent to our client for taking approval for paper color, texture and ink which we are used. When final approval is taking from our honorable clients, scanning process is started with examination of the film to identify scratches, tears, reels without headers, etc. If problems are found, we notify our client so that adjustments can be made at our well equipped laboratory.

During the process of scanning, disagreement or dissimilarity is present in the film density are automatically adjusted and are manually verified. Then we automatically situate the position of each individual image within the scanned output and proceed to quality check up. Because quality is our prime concern, our several quality inspectors simultaneously verify the quality of the scanning since quality confirmation. It takes much more time than the actual scanning process. Wide collection of validations is carefully accomplished.  If corrections are required, they are done immediately at the inspection station.

Before making duplicate file, the film that was originally exposed in the camera is inspected for proper resolution and density. To check proper resolution & density, this film goes a methylene blue test that is used for residual thiosulfate from processing. This film also undergoes a polysulfide test (as needed, if polysulfiding treatment was applied during original processing) are conducted. Then the film that was originally exposed in the camera is inspected frame-by-frame to make sure that each document has been filmed in the correct order and each frame is readable. If necessary, mistakes are corrected using ultrasonic merging.

After that the images are indexed according to prearranged criterion.  Folders can be created by name, number, date, department, etc. Individual documents can be identified with metadata such as document category, date, topic, theme, etc.  Credentials and folders that exist of more than one image will be divided into multi-image files. Files are then processed for most wanted file type like Tagged Image File Format, JPEG, PDF and others. If needed, the grayscale images are converted to black and white (bi-tonal) format.

To making duplicate files, choice of film will be depend on cost and patterns that are used. Normally, silver film is appropriate for duplicate negatives, and should receive a polysulfide treatment. Diazo and Vesicular Films, which are cheaper and less horizontal to scratching than silver films, are often used for service copies. Vesicular Film is also known as Kalvar. It is type of photographic film that is sensitive only to ultraviolet light and developed simply by heating the exposed film. Duplicate films are then examined for resolution, density, and completeness.

After that, original materials are usually returned at the same time to facilitate domestic inspection of the film. But the film that was formerly showing in the camera should never be dispatched in the same box, or on the similar day, with their duplicate negatives. Rather than, master negatives should be shipped by the vendor directly to offsite storage under the proper temperature and humidity conditions.

At last our quality control staff members give confirmation that the steps above have been correctly executed.  We statistically examine the final output to assure that image quality, file generation and output formatting is perfect. We can broadcast images through protected and encrypted FTP protocol or record the data to CDs, DVDs or External hard disk drives.
