| Note that colors may be regarded as black and white in the following kinds of |
|
| documents. |
-Faintly toned paper
-Partially colored documents
To scan such documents in color mode, select "Color" as "Color mode."
•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 scanning photographs or figures because these graphical materials are recognized as background and com- pressed 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 characters written in black
-Documents of complex layout (e.g. multiple columns)
-Documents with patterned background
