Parameter Option Description
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.
Image halftone
screen Provides the following options:
Note: If you select the Dot 2, Line 1 or Line 2 options for a job that
will be printed, make sure that you also select Permission in the
Image Quality Setting screen on the printer's touch panel.
● Dot 1—Applies a high dot-type screen
● Dot 2—Applies a medium dot-type screen
● Line 1—Applies a high line-type screen
● Line 2—Applies a medium line-type screen
● Stochastic—Stochastic screening differs from conventional
halftone screening in that high ink density results in more dots,
not bigger dots. Low ink density produces fewer dots, not
smaller dots. As stochastic screening involves millions of
minuscule dots, many more than are used for conventional
halftone screening.
Notes:
● If the Stochastic option is selected, make sure that the Text
Thinning, Text Smoothing, and Halftone Text Enhancement
options are not selected and that the Resolution option is set to
600 dpi.
● If the Resolution option is set to 1200 dpi, make sure that
Image screening and Text/graphics screening options use
the same settings.
