JBIG2 Technical Advantages for Business Solutions
First: Do No Harm
The key for JBIG2 use in compressing documents that need to be archived or that have strict retention requirements is that the JBIG2 encoding be reliable and not lose any informational content. One way to measure informational loss effectively in an automated environment is through an OCR (optical character recognition) program which can verify that recognition rates are as high after JBIG2 compression as before.
Although JBIG2 compression can be used in lossless mode, it is far more effective when used in a perceptually lossless mode. Most of the file size in a lossless encoding is used to encode sensor noise and other digitization artifacts not germane to the file's informational content. Though lossy JBIG2 can result in much more compact file sizes, it is very important to ensure that the lossy encoding is, in fact, perceptually lossless as described in the previous section of this Primer. Character mismatches and degraded OCR recognition are not acceptable in a perceptually lossless JBIG2 encoding. In other words, a cheaper JBIG2 solution could be much more expensive in the long run.
