Document Halftone
Halftone is the process by which images are printed as a 
pattern of many small dots. The size and density of the 
dots produce shades of light and dark in the image when 
it is printed. Also, different combinations of the four 
primary toner colors produce an extensive range of 
possible colors. You can choose from three Halftone 
Settings--Quad Dot, Smooth Screen and 1200 Quality.
• Quad  Dot
Quad Dot produces clear, well-defined pictures and 
graphics. It could result in faster printing.
• Smooth Screen
Smooth Screen halftones distribute the halftone dots 
in a more random pattern in order to produce a 
smoother effect for color sweeps. It also provides 
smoother fine lines with less visible grain.
• 1200 Quality
1200 Quality produces a smooth gradation of tones 
and finer detail in images such as photographs. You 
can use this feature to produce finer halftone steps and 
more grayscales.
