PS Overprint
In the client authoring tools (for example QuarkXPress®), you can select
overprint options.
PS Overprint
offers the option to use the overprint,
which exists in the PostScript file. It also determines whether the DTP
application PS Overprint settings are honored in the RIP.
The Spire CXP6000 color server settings override PS Overprint commands
from DTP applications. For example, if you set the PS Overprint option to
Yes
in a DTP application, and in the Spire CXP6000 color server set the PS
Overprint option to
No
, the result is no overprinting. The Spire CXP6000
color server can’t create PS Overprint that is not pre-defined in the file. If
you select the
Yes
option (default) for a file that has not had overprinting
defined in a DTP application, the result is no overprinting.
If you choose to keep the PS overprint that was applied in a DTP
application, the Spire CXP6000 color server implements the overprinting
and background colors are not knocked out. For example, in the case of a
yellow triangle overlapping a cyan circle, selecting
Yes
results in the
overlapping area turning green. This is not seen on the screen, only in
print.
Note: The above is true for files with PS Overprint Yes already selected in the
DTP application.
