Halftone Pattern
8
The machine can use two methods (Diffusion or Dither) to arrange dots to express halftones. There are
some predefined patterns and you can choose which one to use for your document.
 Diffusion
Dots are put at random to create the halftones. Use for printing photographs that have delicate shades and
graphics.
 Dither
Dots are arranged in a pre-defined pattern to make halftones. Use for printing graphics that have definite
colour boundaries or for printing charts such as business charts.
