[Basic] Tab

Change the compression rate for creating PDF files from scanned document images.

Compression RateMove the slider bar to change the compression rate.

The compression rate can be changed in five levels from 1 to 5. (By default, the compression rate is set to 3.)

Moving the slider bar to right increases the compression rate. Higher the compression rate, the smaller the file size, but the image quality is degraded. This setting takes effect on color images only. When images are saved as monochrome images, this setting is ignored.

[Color High Compression] Checkbox

When this checkbox is marked, image portions in a color image are compressed at a higher rate separately from text. Therefore, when a document containing mostly text is scanned, the file size can be made smaller without causing text to become blurred. This setting is not suitable for scanning photographs and figures because the image quality of highly-compressed photographs and figures is degraded.
