PRINTER FUNCTIONS
G130/G131 6-82 SM
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). If the "Text Priority" is selected
with the "4C Graphic Mode" in the UP mode, the maximum values of the photos
are the same as the values of the text.
• 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.
