RIPping through data - Challenges faced in the digital front end
"The challenge isn’t just to be fast enough", says Global Graphics' chief technology officer, Martin Bailey. "The real challenge is to achieve that goal without incurring an uneconomically high cost for the bill of materials to build the Digital Front End." • Digital Front Ends (DFE) Face Rapidly Increasing Data Processing Requirements as Print Jobs become More Complex o Increased Use of Transparency o Need for Increased Variable Data Coverage • Race for Speed is On-going Competitive Challenge o DFE Must Process Data Quickly Enough to Drive Press at Full Rated Speed o Press Manufacturers want to Minimize DFE Costs Vs. Cost of Press o Must Respond to Market Needs & Opportunities: Photobooks, Personalized Marketing Materials, etc. • The Holy Trinity o Speed, Quality & Reliability • Once the Hardware is Optimized – What Then?

RIPping through data - Challenges faced in the digital front end
- 4. Job management (submission, status, view, edit, cancel, etc.)
- 5. Color, ink, and media management
- 6. Imposition and finishing management and control
- 11. A standard mid-range digital press (120 PPM) requires the processing of over one hundred million pixels every second, worst-case, with possibly multiple transforms, and in 4 (or more) colors
- 12. HP’s high-end presses (like the T400 below) require nearly three billion pixels every second
- 13. The primary performance goal for a DFE is to process any job or workflow at or above press speed – strive to always have the DFE outpace the press over a shift
- 18. Higher paper speeds/pages per minute
- 21. Better data mining techniques
- 23. Expanding out of general design practice for books, publication, POD, print-for-pay and general commercial print
- 29. Define which sets of pages go together in a hierarchical structure
- 30. E.g. as components that will be supplied to a single direct mail recipient
- 38. Multiple cores per CPU
- 39. Multiple physical disks per machine
- 40. Multiple physical disks per logical disk
- 41. Multiple (teamed/bonded) network interfaces per logical network connection
- 42. Multiple RIPs per machine
