Toner Limitation - Gestetner B147 Service Manual

Toner Limitation

Toner limitation prevents toner from being scattered around text or printed lines.
Maximum values have been prepared independently for text and photo. They can
be adjusted with controller SP mode (Toner Limit).
• Default: 190% for text, 260% for photo
• Adjustable range: 100% to 400%
Dither Processing and ROP/RIP
Dither patterns have been prepared for photo and text independently. Dithering
converts 8-bit data to 1-bit or 2-bit data. However, these dither patterns create the
illusion of 256 gradations for high quality prints. The optimum dither pattern is
selected depending on the selected resolution.
