When "High Compression for Color PDF" is selected, characters and back-

grounds on the document are compressed separately. In order to do this, the

file size of the document that mostly consists of text characters becomes

smaller while keeping the quality of the characters as they are. However, this

mode is not appropriate for scanning photographs or pictures since these

graphical materials are recognized as background and compressed as such,

causing degradation in the scanned image. If this setting is specified, the con-

trast of the image may become higher.

If "High Compression for Color PDF" is selected, according to the type of docu-

ment, the file size may be larger than if a standard compression level is used.

Documents with many photographs or figures and only a few characters

Complex layout documents with multiple columns

Documents which have a background pattern behind characters

For documents with many characters scanned at 300dpi resolution, a smaller

file size than that of High Compression for Color PDF is possible.

When one color page is scanned, the file size criteria are shown as follows.

These numbers are for reference, other documents may vary in size.
