Printing from the color
server
The CX print server features the Adobe PDF Print Engine (APPE)
RIP as a complementary workflow to the CPSI RIP, enabling you
to use the RIP that is appropriate for each job. The APPE RIP is
particularly useful for files that need transparencies and overprint
handling. APPE RIP information is added to the job history and
workspace.
The main benefit of the APPE RIP is that complex designs and
effects, including transparencies, can be reproduced reliably.
Designers and printers can make late-stage edits in PDF files more
easily and configure PDF jobs for printing on different types of
output devices and presses.
The APPE RIP applies to PDF files only. If you use Smart mode or
Force mode with a non-PDF file, the system ignores your selection
and renders with the CPSI RIP. Similarly, when the PostScript
driver translates a PDF file to PostScript, the system uses the
CPSI RIP.
The Smart mode option lets the system determine when to apply
the APPE RIP. In Smart mode, the CX print server analyzes your
file and applies an automatic workflow that optimizes the RIP
method. For example, if a file has text only, the system recognizes
that the file does not require the APPE RIP and processes the file
with the CPSI RIP. In Smart mode, the system also checks for
transparencies that use various color spaces and for spot colors
that use overprints.
One of the advantages of using a PDF workflow is that you can
work with embedded ICC profiles. The CX print server includes
APPE RIP support for both CMYK and RGB embedded ICC
profiles.
The CX print server is fully compatible with PDF/X-1a, PDF/X-3,
and PDF/X-4. PDF/X files are a subset of PDF files whose
standard provides for the exchange of final print-ready pages.
Using PDF/X-compliant files eliminates the most common errors in
file preparation (for example, fonts that are not embedded,
incorrect color spaces, missing images, and overprinting or
trapping problems).
