Screen as
To assign a different default spot color screen angle, select a
color in the list.
For IS screening, Prinergy cannot assign the
Others
angle as the
default spot color angle.
Cycle Through Screen Angles
Select this option to assign default spot color screen angles
cyclically to the available process colors, in CMYK order.
Prinergy does not assign process colors that have already been
used to screen a spot color.
If
Staccato Extended
is selected in the
Screen System
list, the
list of screens cycles from
Screen #1
through to
Screen #10
.
For IS screening, Prinergy cannot cycle through angles other
than CMYK.
Do not increase yellow ruling
To reduce moiré, the AM screening algorithm provides yellow
screen frequencies (lpi) that are up to 14% higher than the
cyan, magenta, and black screens. If you want a Y screen that is
more similar to the Y screen in Prinergy 2.2 and earlier, select
this check box. It limits yellow screen frequencies to between
-4% and 4% of the ruling of the C, M, and K screens. For
example, if the C, M, and K screens are at 150 lpi, this check box
limits the screening algorithm to providing a Y screen between
144 lpi and 156 lpi.
This setting does not affect the yellow frequency of an IS screen
set. To change the yellow frequency of an IS screen set, use the
IS Screen Set Editor.
Rotate Screens With Pages
Select to rotate screens with reader orientation for each page in
an imposition.
When some pages are rotated 90°, rotating screens with the
pages allows all pages to be screened at the same angle.
Screens are only rotated at 90° so pages that are oriented at
other angles are not affected. The result of rotating screens is
apparent when you screen with dot shapes that are not
rotationally symmetric, such as Elliptical and Line.
