SDTC, DTC mode

To enable the auto binary function of the image scanner, specify this option. If this option is selected, the "Threshold" setting will be disabled.

In addition, auto binary has two modes: " SDTC Mode" and "DTC Mode". These modes can be set using the "Advance" dialog box.

"DTC Mode", however, is limited to the image processing options. Therefore, only scanner models that have image processing options support "DTC Mode". See "Relevant Image Scanner Specification" in the Appendix.

SDTC mode (Floating Slice)

This option enables scanning and fine binary processing for documents whose backgrounds are other than white such as newspapers.

Some scanner models do not support this option. See "Image Scanner Specification" in Appendix.

Advanced DTC

Scan in fine binary mode regardless of the document.

Normal binary mode can’t scan very well faintly toned documents, documents with colored background, or documents with color charts. Choose this to scan these documents clearly.

♦Halftone

Select the halftone pattern for halftone scanning from the built- in pattern list.

Select the desired halftone pattern for displaying the obtained image. This setting is effective when "Halftone" or "Automatic Separation" is selected in "Image Mode".

Some scanner models do not support this function. See "Relevant Image Scanner Specification" in Appendix.

Dither Pattern 0

Executes pattern processing that is suitable for scanning a dark photograph.

Dither Pattern 1

Executes pattern processing that is suitable for scanning a dark-colored document containing both text and photographs.

Dither Pattern 2

Executes pattern processing that is suitable for scanning a light photograph.

Dither Pattern 3

Executes pattern processing that is suitable for scanning a light-colored document containing both text and photographs.

Download Pattern

Executes processing using the dithered download pattern specified in the dithered download file (described later). Some scanner models do not support this function. See "Image Scanner Specification" in Appendix.

Error Diffusion

Error Diffusion minimizes the difference between the pixel density of the scanned image and the pixel density of the printed image to create better reproduction of a scanned photograph.
