• Document image files are usually very large due to the background, which is often makes up to 90% of the file size. The background may, however, be unnecessary in the resulting document. It is the text and pictures that are important.
• The MRC compression technology allows locating the color background and deleting it or compressing to a high degree. This leaves text and pictures against a white background, contributing to smaller file size.
• Picture objects (diagrams, graphs, logos, photos, drawings, stamps, signatures, etc.) are also slightly compressed, but only to an extent that doesn’t lower the quality.
• The MRC technology analyzes the outlines of similar characters in the document, creates an average character template and uses it instead of a character itself. This leads to better readability, because some of the text defects are corrected, and the character outlines become more precise.
• As a result, you get a smaller image which looks even better than before. The resulting document will have an unobtrusive, bland background with fine text and pictures.
• This “reconstruction” of the document can be useful when you have to deal with low quality images due to: bad lighting, out-of-focus photo, incorrect scanning/photo parameters, dark uncoated paper, or document dilapidation.
