Dither Pattern Settings
If you want to change the gradation pattern of a printed image, specify the dither pattern
settings. Dithering is a technique used to create the illusion of colour depth in images by a
diffusion of coloured dots. A dither pattern is the data used for arranging coloured dots.
A dither pattern can be selected for each of the following:
■
Gradation (For Printer)
You can select [Gradation], [Resolution], or [Error Diffusion] independently for texts, graphics, and
images for the halftone settings of the printer. This mode enables you to select the dither pattern when
you select [Gradation] as the halftone setting. For instructions on setting halftone of the printer, see the
PS/PCL/UFR II Printer Guide .
■
Resolution (For Printer)
You can select [Gradation], [Resolution], or [Error Diffusion] independently for texts, graphics, and
images for the halftone settings of the printer. This mode enables you to select the dither pattern when
you select [Resolution] as the halftone setting. For instructions on setting halftone of the printer, see the
PS/PCL/UFR II Printer Guide .

Reproduce Scan Image

ex.) If you select [Color Tones] for [Resolution (For Printer)]
