3.4 Changing Scan Settings

Color mode:

Specify whether to scan documents in color or black-and-white.

Select one of the following modes:

Auto Color Detection (Automatically recognize each document color)

ScanSnap automatically recognizes whether the document to scan is colored or black-and-white and switches the scan mode accordingly.

Color

Scans the document in the color mode.

This setting is ideal for scanning colored documents.

B&W

Scans the document in the B&W mode.

This setting is ideal for scanning black-and-white documents containing mostly text. File sizes can also be kept smaller at the B&W setting compared to the color mode.

Color high compression

Saves colored documents as a highly compressed file.

Normally, set this setting to "Auto Color Detection."

HINT

 

If this setting is specified, there is no need to change the color mode each time

 

 

 

 

you scan a document.

 

 

 

 

 

 

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
