Parameter Option Description
Trapping Enable trapping Applies trapping to your job.
Trapping is a solution that solves misregistration between color
separations in both offset and digital printing. Misregistration can
occur regardless of a printing device's accuracy and results in white
lines around objects on top of a background (in a knockout) and
also between adjacent colors.
Note: If you don't select this option, it does not affect trapping
incorporated in DTP software—for example, Photoshop. The IC-312
print controller trapping should not be used with the trapping options
included in DTP software. In a PostScript file that already contains
trapping from the originating application, it is not necessary to use
IC-312 print controller trapping.
Provides the following options:
● Frame thickness—Enables you to set a value for the thickness
of the trapping frame. The thicker the frame, the less chance
that white areas appear between images.
● Protect small text—Does not frame text that is 12 points or less
when the trapping algorithm is applied. You can use this option
for small or complex images, because thicker frames can
decrease quality by hiding parts of an image.
Overprint Black overprint Ensures that black text prints cleanly within a tint or picture area.
The text appears in a richer, deeper black, with the underlying CMY
values equal to those of the printed background.
PostScript
overprint Uses the overprint information that exists in the PostScript file. This
option also determines whether the DTP application's PostScript
overprint settings are retained in the RIP.
Resolution Resolution Enables you to set the resolution for the job when printed. Select
either 600 dpi (fine) or 1200 dpi (very fine).
Printer
settings Printer Quality
Enhancements Apply printer quality enhancements—Enables you to select
which elements in your job you want to improve the quality of the
edges. You can apply this to Text, graphics and images, or Text
and graphics.
Text thinning—Improves the jagged edges that may result in cases
where transparent elements are overlaid on text or vector elements.
For best results, use this option when graphic elements
unexpectedly expand—for example, bolded text.
Halftone text enhancement—Enhances jagged edges of halftone
text and graphics. An outline is added to the jagged edges
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.
