JDF – An JDF – An Overview Overview
JDF Technology on One Slide
• JDF is a Graphic Arts Job Ticket Data Interchange Format Specification - JDF is not an Application or System
• JDF is encoded in XML
• Content is referenced, not embedded
• JDF is extensible
• JDF Job Definition + JMF Messaging +JDF Capabilities + ICS Documents define the JDF Framework
JDF on Another Slide- Goals and Requirements -
• Why JDF?
– Automation increases Efficiency
– Information allows for informed decisions
– We have a digital content workflow with a paper based management workflow – there is room for improvement!
• What does JDF enable?
– Setup a Job in the graphic arts from the view point of:
• Technical Applications
• Management Information Systems
• Customers
– Collect data that is relevant to a Job from origination to delivery
• Business Data
• Technical Data
History of 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 enhanced2004: JDF 1.2 is released
– More additional processes
– Even more mature and consistent 2005: First set of ICS documents are published
JDF 1.3 will be released– More additional processes
– Even more mature and consistent

JDF in the
workflow
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 both Products and Processes
Input (Resources) Output (Resources)JDFNode
Start End
TimeScheduling
Auditing
PrintTalk – www.printtalk.org
• JDF describes the product to be produced
• PrintTalk describes the business context of the product
– Request For Quote
– Quotation
– Purchase Order
– Invoice
– Change Order
– …
• PrintTalk also contains Pricing Information
Product Intent vs. Process Modeling
• Goal of Product Intent Description– Customers view of the “thing” they want to manufacture
– Contract Negotiation
– Process Independent

Product Intent vs. Process Modeling
• Goal of Process Modeling – Interface between MIS and Production– Process interdependencies – Manufacturing Instruction Details
Gray Boxes
• Incomplete Model of a Process• The MIS View of the process
– It’s only important if it affects the cost!– Thus, parameters not affecting costs are not
important
• Exact Process execution is potentially undefined– Ordering of steps is not necessarily predefined– Detailed Work Steps may be left out
• E.g. MIS knows RIPping, but not Trapping or ColorSpaceConversion
Audit Objects in the JDF Ticket
• Logging of Job Execution– Actual times
• Start time
• End time
• Phases
• Logging of Late Changes– Resources (used 85g Paper instead of 80g)
– Consumables
• Status Summary • Event Log
JMF Messaging
• Semi Real-time data interchange format
• Small XML structures– JDF is referenced via URL, not bound into
message
– Idea is to minimize network traffic and delay transmission of data until it is actually needed
– Send potentially interesting information as soon as it is available
JMF Messaging
• Used for:– Plug + Play bootstrapping (Future)
– Snapshots of Job / Device status
– Dynamic job update (Change Orders)
– Job submission and Queue/QueueEntry handling
• Generally used within an Intranet
JDF in Creative
• Specify the Context of a Page – Is it a Cover?

• Specify Product Details– Media to use
– Binding Options
– Color Options
• Track Times spent on Creative Work• Specify Deadlines
