Epson Stylus Color 740 Ink Jet Printer  Selected FAQ  What is
halftone printing? In order to simulate varying size halftone
dots in computer printers, dithering is used, which creates
clusters of dots in a "halftone cell." We recommend using Error
Diffusion when printing halftoning. The more dots printed in the
cell, the darker the gray. As the screen frequency gets higher
(more lines per inch), there is less room for dots in the cell,
reducing the number of gray levels that can be generated.
Epson's (LPI) lines per inch conversions are as follows:  720
dpi equates to 240 lpi  360 dpi equates to 120 lpi  Was this
