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.
If you select the proper dither pattern for printing, you can make printed images with both smooth gradation and outlines.
