File processing

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).
