COMPUTER-INTEGRATED MANUFACTURING -- Systems that Serve a Greater Good
For a shop's internal workflow, Prinergy Version 2.2 features the new Creo PDF Trapper, offering enhanced functionality and greater ease. (The system's existing PDF-to-PDF vector trapping capabilities are retained.) The upgrade also provides complete ICC-based color management and features improved versions of the Creo Virtual Proofing System software for Mac OS X and Windows.
Heidelberg has taken a tiered approach in developing workflow solutions, reports Dennis Ryan, prepress product manager for Heidelberg USA. MetaDimension serves as an entry-level system for offset and digital print production, but it also can be incorporated into the Prinect Printready system to create an automated, PDF-based workflow that implements JDF.
MetaDimension is a RIP-centric workflow—upgraded to the Adobe 3016 interpreter with version 4.0—that supports processing of PostScript and PDF files. It implements PJTF (Adobe Portable Job Ticket Format ), not JDF, to enable creation of output plans that direct the processing of jobs, Ryan notes.
Through a sequencing process, MetaDimension can also be integrated into a Printready system to handle rendering functions. Once configured, it ceases to function as a standalone product and no longer uses PJTF, Ryan says. "Every processing task happens in the Printready system as a true JDF event," he points out.
How the system handles impositioning is a good example, the product manager says. An imposition plan can be brought into the system via JDF import and then anyone with client software can assign pages to the plan, he explains.
Avoiding an Overload
As Heidelberg extends its implementation of JDF to the pressroom and on through finishing operations, Ryan says he can see advantages to having a separate master JDF server connected to every area of a plant. "You probably don't want all areas of production hitting into your prepress server," he notes.
Screen (USA) is another company taking a layered approach to its workflow solutions. While continuing to offer its Trueflow system for high-end, PDF-based workflows, at this year's GRAPH EXPO the company announced it was becoming a reseller of Electronic For Imaging's (EFI) Velocity OneFlow prepress software. Both systems are said to integrate with Trueflownet, Screen's JDF-based, end-to-end workflow concept.
