The Business Case for JBIG2 Compression

Return on Investment

The value proposition for JBIG2-PDF compression, optimization, and search has four main components:

    1.   Storage space savings. Compressing bitonal files can restore virtually 90% of your available storage capacity. Color files compress more than bitonal files, so color compression can restore over 98% of your company's existing storage space. Before spending needlessly on more storage space, you could batch compress all your PDFs. It is similarly advisable to convert TIFF and JPEG files to PDF and compress them at the same time. That way, all of your files will be viewable on demand, fully web-optimized and text-searchable. These compressed files will use dramatically less space and the files can always be restored to their native format if necessary.

    2.   Efficiently Web-host and email documents. Compression brings a cost savings inherent in using less bandwidth and eliminating overage charges. If you are transmitting files over the Internet or Intranet, you'll use 90%-98% less bandwidth by transmitting compressed PDF files. In addition, you will be able to email corporate files, monthly statements and newsletters without exceeding email attachment file size limitations.

    3.   Benefit from increased speed of transmission. Time is money for both the sender and receiver of an electronic transmission. JBIG2-compressed PDFs can deliver up to 10x faster transmission speeds than uncompressed PDFs. Consider these transmission time comparisons to upload over a 50 kb/sec connection:

PDFs, TIFFs and JPEGs can take a very long time to transmit and receive, even with a high-speed Internet connection. With compressed PDFs, a file that used to take 10 minutes to transmit would take 1 minute. That difference may be hard to measure in a direct dollar for dollar savings equation, but anyone who has ever waited 10 minutes to download a file knows the importance of speed.

    4.   Utilize OCR to retrieve files efficiently. Applying OCR to scanned documents makes them fully text-searchable and easy to retrieve. Many scanned corporate and litigation files would benefit from full text indexing and searchability. Most of these files are currently just field coded with a very limited field set in order to reduce costs. This limits the usefulness of captured documents since only these fields can be queried. By converting scanned documents from traditional formats such as TIFF to PDF, it becomes very easy to add a "hidden" OCR text layer and support full text search across the entire corporate database.

JBIG2 Compression Success Stories

File size is a technology problem. For anyone who deals with a large amount of paper, compression is a huge advantage. PDF compression technology enabled through JBIG2 makes document storage, retrieval and presentation both secure and fast.

Digital media compression is proving itself to be a valuable practice in document-sensitive businesses. The following stories offer just a few actual cases where compression has delivered the kinds of ROI addressed in the previous section.

From the Legal Industry

Documents drive the legal profession. Court documents, legal briefs, discovery documents and depositions come together to make an ocean of paper in most law offices. Taking hard copy into the digital realm is a great start in taming that paper ocean. But a few years ago, the knowledge and management staff at New York's Cleary Gottlieb Steen & Hamilton LLP realized that digitizing alone wasn't enough.

"We were scanning 300-by-300 dpi images of the documents that came to our office," said Matthew Roeder, Imaging Technology Analyst for the firm. "If it was paper, we were scanning it. We used an OCR technology to create text searchable PDF images, and people loved it, but the file sizes were huge.

"We needed compression. I think it was about then that one of our staff met CVISION Technologies at the Legal Tech event. CVISION seemed to be ahead of the pack in compression technology. The technology was great - and they directed us to a customized version of PdfCompressor sold and supported by Captiva that's 100% integrated with InputAccel. Since we've adopted InputAccel firm-wide, that was just icing on the cake!"

In the legal world, a hundred-page document is common. If someone wants to send a 100-page scanned document via e-mail to a client or co-worker with a four megabyte file size limitation, it usually bounces back. File size also makes it difficult for attorneys to download portable case documents.

Matthew Roeder continued, "The compression capabilities we get from CVISION means one of our lawyers can easily take two to three thousand pages of documents off a database, download it to a laptop, and work on a case on the plane. Attorneys at remote trial sites can access documents from our office very quickly. Clients can easily retrieve and view documents relevant to their cases. That's exactly the kind of document portability we needed."

From Homeland Security

Nobody takes image files more seriously than the IT professionals involved with homeland security.

That's why Nate Lindstrom, Business Consultant for Black & Veatch in Overland Park, Kansas, looked for fast, solid solutions for the issues he faced with homeland security-related documents. Black & Veatch had image files to be converted into PDF files for simultaneous viewing by people at a number of sites along the Homeland Security network.

"Our file sizes can be pretty massive. We have both color and black-and-white files to deal with, and have complex content," Lindstrom said. "The key was to find compression that allowed storage on a data base quickly.

"CVISION's OCR product is about as good as it gets right now," Lindstrom added. "And the compression is absolutely amazing. We can achieve compression ratios of 9x or 10x with ease, and often see compression ratios higher than that!

"We constantly face high pressure deadlines. Documents circulate throughout the Homeland Security network to Congress and back. To my knowledge, there have been no compression or imaging hitches since we implemented CVISION Technologies."

From the Media Monitoring Industry

The Express media monitoring service of BurrellesLuce starts with a sophisticated search system of print and online media. In the form of scanned pages, those results go to seasoned editors who filter unnecessary information from the product that is finally transmitted to clients.

The human touch is critical to the accuracy and usefulness of the final product to Express clients. Keeping the Express service running on an accelerated schedule means the process has to be streamlined for speed. That's no small task, according to BurrellesLuce CIO Jeff Gubbins.

According to Gubbins, scanners pick up the newspapers as early as possible in 32 remote locations. The papers are scanned and sent into the BurrellesLuce facility, edited and sent on to the client. The goal for the Express service is to have client files available to them as early as 7:00 a.m., so saving time in the process is important.

"We use CVISION compression technology to handle full page newspaper scans in our remote locations. Once we transport those files, we decompress with CVISION and put the files into the Express service for our clients," Gubbins said. "Basically, a raw scan of a newspaper page is 25 MB. The scanning software that we use brings it down to 5.5 MB. CVISION takes that file to about 1.3 MB," Gubbins added. "Because we're transporting those files over DSL or cable modem from many of our remote scanning locations, that final compression step CVISION gives us saves a lot of time. Time is of the essence in our Express service, and CVISION compression saves time in transmission."
