  1. Dr. Rainer Prosi CTO, CIP4 Senior Software Architect, Heidelberg Inside JDF Experience and Challenge

  2. Outline • Architectural Overview of JDF • Experience with JDF 1.1 • Outline of JDF 1.2 Activities • Areas of activity (Who and What) • Cooperation with other standards • Timeline for JDF 1.2 • JDF Interoperability Status

  3. JDF on One Slide • JDF is a Graphic Arts Job TicketData Interchange Format Specification- JDF is not an Application or System • JDF is encoded in XML • Content is referenced, not embedded • JDF is extensible • JDF is based on semantic structures defined by: • Adobe PJTF • CIP3 PPF • JDF Job Definition + JMF Messaging define the JDF Framework

  4. The Building Blocks of the JDF Framework • JDF Node • Description of a Process, Process Group or Product • JDF Resource • Description of a parameter set or physical entity • JDF ResourceLink • Link between JDF Nodes (processes) and Resources • JDF Capabilities Descriptions • Limitation of a JDF interface • JMF Messages • Real time data interchange format

  5. The JDF Node • Description of a generic Process • The “Verb” in JDF • Do something at a given time • Structured container for Scheduling and Auditing • One JDF node type for Products and Processes • Less Precise Product Intent at the Job Root Node • Workflow Group nodes “ProcessGroup” in between • Detailed individual or combined Processes in the Leaf Nodes

  6. Book Contents Cover Reader Pages End Sheets Product Intent vs. Process Modeling • Goal of Product Intent Description • Customers view of the “thing” that he wants to have manufactured • Contract Negotiation • Process Independent • Goal of Process Modeling • Interface between production and management information systems • Process interdependencies • Manufacturing Instruction Details

  7. JDF Resources • Specification of Parameters of • Product Intent description • Logical Entities, e.g RIP Parameters, Imposition setup • Physical Entities, e.g. Media, Devices, Plates • Based on Adobe PJTF and CIP3 PPF • Intent Resources for product intent nodes • Prepress : Adobe PJTF • Press, Finishing: CIP3 PPF • Internal to JDF or External Links to well-defined Formats • Thumbnails • Preview Files • ICC Profiles • Content Data

  8. Parent Node Resource 1 Child Node 1 Child Node 2 Link ResourceLink • Bind a Resource to a Node • Define Resource Usage (input or output) • Link to a Subset / Part of a Resource • E.g. Cyan Plate of the Front of Sheet #1 • Define the Amount • Allow reuse of Resources by multiple processes • One resource may be linked by multiple ResourceLinks • Defines a process network

  15. Capabilities Descriptions • Mapping from Product Intent to Process Networks • Set up Communication between Controllers and Devices • Define User Interface Constraints • Allow planning systems to automatically schedule jobs to the optimal available device. • Enable load balancing between devices. • JMF messages for Capabilities Integration (Plug&Play)

  16. Messaging with JMF • Small XML Structures • Synchronized with JDF • Used for: • Plug + Play Bootstrapping • Snapshots of Job / Device Status • Dynamic Job update • Queue Support • Capabilities interchange

  17. Experience with JDF 1999: Adobe, Agfa, MAN and Heidelberg form the GAT initiative with the goal of defining a job ticket for the Graphic Arts that also integrates MIS. 2000: The CIP3 Consortium takes ownership of the standard. 2001: JDF 1.0 is released. 2002: JDF 1.1 is released. • Ambiguities/Bugs found in implementation were removed • Additional Processes were added • Consistency between diverse areas was enhanced

  18. Experience with JDF - Advantages • Single grammar for specifying job data in the graphic arts industry • Integration of Production, Customer and MIS • Definition of production networks • Combined Processes • Defined communication protocol, not only data structures • Extensible Model • Interaction with other Standards in GA

  19. Experience with JDF - Challenges / Obstacles • Number of processes in the graphic arts • Creative • Prepress • Press • Finishing • Fulfillment • Complexity of the standard • Size of the Specification • Moving from the Abstract Idea to a Concrete Implementation • Flexibility of the Specification • Unclear Role of Production networks in Interfacing • private extensions • Definition of abstract coordinate systems • Legacy System Longevity

  20. Interface Areas in JDF - JDF 1.2 enhancements • Backwards Compatible Extensions of JDF 1.1a • Customer  Print (Graphic Arts) Shop • MIS  Production • Prepress • Press • Postpress • Communication / JMF Messaging • Capabilities • Interoperability Conformance Specification definitions

  21. Customer  Print (Graphic Arts) Shop • Product Intent Definition • Minor Cleanup / Clarifications • Add a “generalized” CustomerMessage element • Add Channel definitions for • Instant Messaging • SMS • Add extensible reason and message content definitions

  22. MIS  Production • Definition of the MIS  Imposition interface • MIS consumes product intent • Imposition Software outputs flattened page positions • Missing Interface from MIS to Imposition Software • Support of multiple customer jobs on a sheet

  23. Prepress • Preflight • Define extensible JDF definition of • Preflight Profiles • Preflight Reports • Asset Transfer • Define a Process for Digital Artwork Delivery • Proofing • Define an integrated combined proofing process

  24. Press • Digital Printing Interface Conformance Specifications • 3 Levels of ICS • Desktop Printers • Department Printers • Graphic Arts Digital Presses • Conventional Printing • Additional Previews for Quality Control

  25. Postpress • Additional Postpress processes added: • Bundling • PrintRoll • Detailed Waste Definitions • WhiteWaste, ObliqueSheets, Process Specific • Complex Feeder Definitions

  26. JMF Messaging • Added Additional Device  MIS messages • Added JMF File Protocol for exchange between very dumb devices/controllers

  27. Capabilities • Abstract User Interface Definitions • Localization • Constraints definitions • Full Boolean logic for device constraints

  28. Standards Bodies that Cooperate with CIP4 • CIP4 Appointed Members extract • CGATS: Graphic arts standards • DDAP: Advertising Workflow • E.R.A: European Rotogravure Association • Euprima: European MIS vendors consortium • GATF: Graphic Arts Technical Foundation • ICC: Color workflow • IFRA • IFRATrack: Messaging for Newspaper production • IDEAlliance • Papinet: Paper Procurement (PrinterPaper Vendor) • Additional IDEAlliance Standards interfaces are under investigation. • NPES: Industry Association • PODI: Variable Data Content Layout Definition • PrintTalk: Internet Print Procurement • TAGA: Technical Association of the Graphic Arts • UP3I: Inline Real Time Finishing and Paper Handling Full list at: http://www.cip4.org/members/members_e.php

  29. Preliminary JDF 1.2 Time Line • Consolidation of miscellaneous Changes • Definition + Discussion 09/03 • Tech Writing : Q3/03 • Integration of Preflight Q3/03 • Internal CIP4 publication • 3 Month intellectual property due diligence period • Official Publication Date

  30. Interoperability Status • CIP4 hosted an Interoperability test event in May • Goals were: • Proof of concept of the event • Integration of products from various vendors • Pinpoint ambiguous areas • Engineering team building • 3 Further events are scheduled this and early next year • Next One is next week in Darmstadt, Germany • Events are closed door • Goal is to enhance the standard and enable interoperability • NOT to find scapegoats / heros
