Konica Minolta bizhub PRESS C1100 - Manual (Page 160)

Parameter Option Description
Color text sharpening—Reduces the toner on the
edge of color text objects to reduce the blur.
Text smoothing— Smooths jagged edges of solid
text and graphics.
Note: This option is not available when the resolution
(selected in the Resolution tab) is set to 1200 dpi.
Screening Screening Converts images, graphics and text into information
that can be printed (halftone dots). The human eye
“smooths out” this information, which seems visually
consistent with the original picture. Thus, the more
lines per inch, the more natural the image appears.
Screening is achieved by printing dots in numerous
shapes or lines in an evenly spaced pattern. The
distance between the screen dots or lines determines
the quality of the image. Printers can work with
constant amounts of toner and still produce a wide
range of colors when you use screening. The darker
the color, the larger the dot.
To print an image on a digital printer or press, the
Creo server needs to digitally approximate the
grayscale values with different distributions of pixels.
This process is commonly referred to as halftoning.
Digital halftoning begins by sampling the original
image at the same number of dots per inch as the
printer and constructing digital halftone cells.
