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.

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

Scanning Parameters

For fine scan adjustments.

Since there is no fixed set of values, set by trial and error.

Brightness:

Sets the brightness of the overall image.

Specify the brightness with a number in the range of 1 (bright) to 255 (dark).

To brighten the overall image, decrease the value of the setting. To darken the overall image, increase the value.

This parameter can be set if "Halftone" or "Automatic Separation" is selected for "Image Mode."

Threshold:

Sets the threshold value by which the black and the white of black-and-white images are distinguished. Specify a number in the range of 1 (bright) to 255 (dark). This parameter can be set only if "Black & White" is specified for "Image Mode."

In addition, if "Auto Binary" is selected, the scanner will automatically use the appropriate threshold value. As a result, the set value cannot be changed.
