Microfilm Scanning

We scan and convert microfilm into digital images from 16mm or 35mm rolls or cartridges. Whether you have one roll or thousands of rolls, we can digitize all your microfilm into high quality images very efficiently and cost-effectively. With over 30 years of experience in scanning, indexing and archiving massive volumes of documents, we know everything there is to know about microfilm digital conversions. Our microfilm scanning services are delivered through our qualified, security-cleared personnel that are dedicated to quality microfilm scanning. We offer microfilm scanning services for (but not limited to):

Superior Equipment & Technology

We use the latest generation microfilm scanners to digitize microfilm of all types, including 16 mm, 35 mm, ANSI C cartridge positive or negative, silver / vesicular / diazo, simplex / duplex, COM, portrait (cine), landscape (comic), etc. Most microfilm scanners attempt to capture individual frames at scan time. However, they can miss frames when the film is inconsistent, which it often is. Our microfilm scanners scan the entire roll of microfilm including areas in between frames. We can then interactively review the results to manually capture any frames that would have been missed. We also adjust the image quality to compensate for the film density changes throughout the roll.

In addition, we use our own proprietary technology to control, streamline and automate all our scanning operations, from A to Z – WizAdmin. It was developed entirely in-house by our expert personnel. Its main purpose is to reduce human intervention to an absolute minimum and remove the risk of human error. This highly sophisticated, one-of-a-kind technology offers complete traceability and provides full real-time reporting functionality.

Microfilm Scanning Process

Microfilm conversion is a multi-step process.

Sample Reel Selection

We begin film scanning by selecting sample reels, inspecting them and scanning a small number of images to properly calibrate the equipment to optimal processing settings that produce the best possible images. The settings are saved in a template before full-scale production commences.

Microfilm Inspection

We inspect the film to identify scratches, tears, reels without headers, check for vinegar syndrome or redox, remove surface obstructions, etc. If problems are found, we follow previously agreed corrective actions or, if necessary, notify you. Reels that fall beyond the range of pre-set processing parameters for optimal legibility will be individually calibrated. Standard settings are only used for rolls that fall within the acceptable range.

Ribbon Scanning

Most microfilm scanners try to output images on-the-fly as the film passes through the machine. This only gives the scanner a single opportunity to perform its frame detection (the process during which the machine recognizes individual frames on a section of film and segments them into separate image files) as well as other necessary computer-intensive tasks such as deskewing, cropping, sharpening, etc. If there is a change in the density of the film (the difference between the lightest and darkest images), an image may be cut in half by a misfiring frame detection process or even skipped entirely. Fixing these types of mistakes requires the identification of a skipped frame (no easy task on a roll containing thousands of images), finding it on the physical roll (even harder), re-scanning it properly, and manually inserting / replacing the re-scans in the original batch of images. This is a very time-consuming and expensive process, which is why most service providers don’t do it.

By capturing each roll of microfilm as a continuous “ribbon” which includes all the empty spaces between the frames on the film as well as the frames themselves, we are able to perform frame detection as many times as required in order to perfectly capture every frame on the roll. Frame boundaries can even be re-drawn by the operator by simply dragging them with a mouse.

Quality Control & Image Enhancement

Our operators spend most of their time on quality control and tweaking images before they are output (not after), so there are no mistakes to correct in the final images. We audit the quality of separate images and, if corrections are needed, they are done immediately. Final quality control confirms that all the above steps have been correctly implemented.

We also perform a number of automated and manual image enhancement functions, such auto white balancing, manual or automatic image rotation, cropping / trimming of edges (e.g. black borders), auto framing, splitting of 2-up frames into individual pages, auto deskewing to remove the slant of an image that prevents it from being perfectly squared on the page or screen, preserving / removing backer board or blip counter digits, etc. Importantly, the SRP Image Enhancement module utilizes a 16-core server dedicated exclusively to post-scan image processing and performs a series of complex algorithmic image enhancement tasks.

Finally, our employees are professional trained in all their work. We get it right the first time and guarantee that we correctly capture 100% of the frames on every roll of film sent to us.

Indexing 

After the microfilm scanning is complete, we can index the scanned documents by manual keying, or other methods. Additional services include OCR for text searchable PDF files, unitizing images into documents, and preparing images and index information for import into your back-end databases and systems, such as your DMS, or any other applications.

Metadata & Image Delivery

Delivery of images and metadata can be done via a Direct File Transfer method (VPN) or External Storage Device method (e.g. encrypted Hard Disk, USB sticks, etc.). You decide which option suits you best.

Image & Metadata File Formats

Here are just a few examples of the possible formats:

  • PDF & PDF/A
  • Image-only or searchable OCR with invisible text under the image
  • Multipage or one file per image
  • JPEG & JPEG2000
  • Uncompressed lossless 8-bit TIFF
  • TIFF Group IV bitonal
  • Structural metadata XML file or CSV file
Other Scanning Options

Here are a few additional options available to you: 

  • Bitonal format (black and white)
  • 256-Color or Grayscale (better preserves fine details like handwriting, rubber stamps, and photographs)
  • Resolution: 100 – 600 dpi true optical resolution (depending on application)
Return, Storage, Destruction

What would you like us to do with your microfilm once scanned?

  • Return your microfilm archive to you
  • Store it in our secure Microfilm Vault (long term storage)
  • Securely destroy your microfilm and provide you with a confidential destruction certificate
