• In "Color high compression" mode, characters and backgrounds on the docu-
ment are compressed separately, and thus, 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 scan-
ning photographs or figures because these graphical materials are recognized
as background and compressed as such, causing degradation in images. If
this setting is specified, the contrast of the image may become higher.
• Depending on the kinds of documents, file size may increase if you use color
high compression mode than if you do not. The file size of the following kinds
of documents may become larger.
- Documents that contain many pictures and/or graphics but fewer charac-
ters written in black
- Documents of complex layout (e.g. multiple columns)
- Documents with patterned background
