-Faintly toned paper
-Partially colored documents
-Documents printed in two colors; many parts of documents are colored in dark color such as dark gray similar to black
To scan such documents in color mode, select "Color" in the "Color mode"
•In "Color high compression" mode, characters and backgrounds on the document are compressed separately, and thus, the file size of the document that mostly contains text characters becomes smaller while the quality of the characters is kept high.
However, this mode is not appropriate for scanning 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 types of documents, file size may increase if you use color high compression mode than if you do not. The file size of the following types 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
