  – Container (or reference) to machine dependent
    setup data for repeat jobs
  – Fully automatic setup
  – Allow operator intervention
  – Dynamic modifications to running jobs
      JDF Requirements for technical
      applications and devices

• Information from the device
  – Shop floor data collection
  – Container (or reference) to machine dependent
    setup data for future repeat jobs
  – Allow tracking of operator intervention
  – Track device or operator initiated modifications
    of job parameters
MIS and JDF/JMF
       What is an MIS

Software TLAs:
  – MIS: Management Information System
  – ERP: Enterprise Resource Planning
  – MES: Manufacturing Execution System
  – PPS: Production Planning System
  –…
• Print MIS systems are all of the above
  – Specific for Print
  – Also provides information to management
      What is an MIS

• MIS is (possibly) the wrong term
  – MIS is a Role - not always a single system
  – Main tasks:
    • Created Quotations to customers
    • Handles Customer Order Entry
    • Creates Production Jobs and Job Tickets
    • Does Production Scheduling
    • Handles Material Logistics (stock and purchasing)
    • Does Job Tracking and Job Costing
    • Includes Invoicing (Billing) and Accounting
      Before MIS

• Everything was manual
• Paper job tickets passed around
• Information about production written on
  paper
• At job completion, papers were filed
        Before JDF
• MIS manages / tracks information about jobs
• Paper job tickets still passed around
• Information about production written on paper
• Option to have shop floor data collection terminals for
  capturing costing information in real-time
• At job completion, papers are filed
• Data captured by shop floor data collection stored /
  managed by MIS
• Much information managed / tracked by production
  systems still “hidden from MIS
        MIS With JDF
• MIS passes data it knows to JDF-enabled production
  systems or integration system
• JDF-enabled production systems can add more data
  to the JDF ticket
   – Production parameters
   – Costing data
   – General notes
• JDF ticket passed back to MIS
• Bridges the islands of information that used to exist
       Comparison: MIS vs. Integration
       System
• 2 Strategies of Workflow Implementation
  – MIS as the leading system
     • MIS controls individual devices directly
  – Production Integration System as the leading system
     • MIS passes control of individual devices to an integration
       system
     • Integration system controls individual devices

• Products are generally either:
  – an MIS that adds features of Production Control
  – A Production Control System that adds features of an MIS

        MIS View and Gray Boxes

• MIS has incomplete knowledge of a Process
  – It’s only important if it affects the cost!
  – Thus, parameters not affecting costs are often unknown
• Manufacturing details are not all known
  – Prepress is seen as platemaking
     • RIP, Color management, trapping etc. are
       beyond the scope of an typical MIS
     • Imposition may be roughly known
         – Number up
         – Sheet size
         – NO register mark positions

• Solution: Gray Boxes
        Process Description

• Goal of Process Description
  – Interface between MIS and Production
  – Models Process interdependencies
     • Don’t start printing before the plates are made.
  – May contain Manufacturing Instruction Details
        Audit Objects

• Logging of Job Execution Results
   – Actual times
      • Start time
      • End time
      • Job Phases (Setup, Running, Stopped, Cleanup, …)
• Logging of Changes
   – Resources
      • used 85g Paper instead of 80g
      • Used Roll inventory #123, not #456
   – Consumables and produced output:
      • Actual Amounts produced, consumed or wasted
• Status Summary
• Event Log
         The JDF Node – Node Type

• Individual process types and their respective resources are
  defined: for instance
   – 11 General Processes, for instance:
       • Verification
       • Buffer
   – 39 Prepress Processes, for instance:
       • Interpreting
       • ImageSetting
   – 4 Press Processes, for instance:
       • ConventionalPrinting
       • DigitalPrinting
   – 52 Postpress Processes, for instance:
       • Folding
       • Cutting
       • Stitching

• 106 predefined processes in JDF 1.4        (incl. deprecated processes)
        Combination of JDF Nodes

• Don’t recreate a new Process Type for Permutations of known
  Processes!
• Create combinations of multiple defined processes into one
  process, e.g.:
      • online finishing = printing + folding +cutting;
      • in-RIP trapping = trapping + RIPping
• Three types of Combination Nodes
   – Combined Node: All internal interfaces are hidden
      • Smart multi-function device
   – ProcessGroup: Internal nodes are accessible
      • Without Sub elements (Gray Box)
          – MIS view

      • With Sub elements
          – Workflow group in a department
          – Subcontract
      Combined vs. ProcessGroup

•Combined Node or Gray Box (from MIS)

    JDF - Spawning and Merging –
    why?

• Parallel processing requires multiple devices
  that are processing to write information to JDF
  simultaneously
• Must define “Ownership” of a sub-node to
  avoid race conditions.
  – If two applications write at a similar time, the latest
    wins.  Need to ensure that either
     • Only one can be written, or
     • The latest data is certainly the correct data
    JDF - Spawning and Merging –
    how?

• Spawn individual nodes of the JDF Tree for
  independent processing
  – Parallel Processing
  – Subcontracting
• Support for Partitioning – e.g. only sheet #1
• Merge back after processing
  – Retain information added by executing device or
    application
     • Audits
     • Modified Resources
     • Modified Amounts in ResourceLinks

        JMF Messaging


• Semi Real-time data interchange format
  – Small XML structures
  – Uses HTTP as transport protocol
  – Used for:
     • Snapshots of Job / Device status
     • Dynamic job information update (Change Orders)
     • Job submission and Queue/QueueEntry (Job List) handling
     • Plug + Play bootstrapping (Future)

  – Generally used within an Intranet
     • Security issues are under development
      JMF Message Families

• JMF messages fall into six categories
  – Command
     • Receiver is instructed to take an action, or to modify
       the state of something
  – Query
     • Receiver is instructed to return information about
       something. No action is taken, no states are changed
  – Response
     • Used to immediately return result of command or
       query
     • Synchronous messaging – command/query and
       response are exchanged on same open connection
       (HTTP Channel)
       JMF Message Families

• JMF message categories (cont’d)
  – Acknowledge
     • Used to return the result of a command after some time has
       passed
     • Asynchronous messaging – empty response returned
       immediately on same connection as command with
       indication that Acknowledgement will be sent later
  – Signal
     • Used to send notifications of events or change in status
     • Typically result of a query with a subscription embedded in it
     • Subscription sets up persistent channel
  – Registration
     • Request for commands
     • Used to set up triangular workflows
     • E.g. MIS tells prepress to send a Command to Press

      SubmitQueueEntry:
<JMF DeviceID="SP013" SenderID="MIS1“
  TimeStamp="2009-03-05T12:32:48-06:00">
 <Command ID="m1“ Type="SubmitQueueEntry">
   <QueueSubmissionParams
    URL="http://jobserver/getJob?job=10047"
    ReturnJMF="http://jobserver/jmfservice"
     Priority="50"/>
 </Command>
</JMF>
         JMF Message Types

• Example JMF messages that fall within the six categories
   – Command
       • SubmitQueueEntry, AbortQueueEntry, ReturnQueueEntry,
         HoldQueue, ResumeQueue
   – Query
       • KnownControllers, KnownDevices, Status
   – Response
       • Various related to various commands/queries
   – Acknowledgement
       • Various related to various commands/queries
   – Signal
       • Status, Resource, Occupation
   – Registration
       • Resource
       JMF Status Signals

• Complete Tracking of Device Stati over time
• Device sends JMF on:
  – Power up
  – Each Statuschange (begin of a new Phase)
     • Idle [-> Setup] -> Productive [-> Cleanup] -> Idle
  – Shift change, Operator Change
  – “Heartbeat” for long running jobs
     • Every N Seconds
     • Every M Copies of output
  – (Just before) Power down of the device
         JMF Status Signal Definitions

• JobID, JobPartID, Part (e.g. SheetName, Separation…)
• Job Status: closed list with <10 values (Waiting, InProgress,
  Completed, Aborted…)
• Device Status: closed list with <10 values (Running, Down,
  Idle…)

• StatusDetails: Open List with initial list of predefined
  values
• List of active modules (# press modules, varnishing, …)
• Operation Mode (Productive, Maintenance…)
      Comparison: JMF Status – Reason Codes

• JMF Status               • Reason/Job Codes
  – „Plug and Play“          – Customizable
  – Detailed Information     – Requires
                               Customization to

         JDF Capabilities



It’s all about
Interoperability !!!



If you don’t know about
capabilities, you won’t be
able to “interoperate”…
It’s all about Interoperability!!




                     But if you do, you can use
                     the right tools…
       What can Capabilities be used For?


• Determining what products a print shop
  could produce.
   – Allows the creation of JDF Intent (product descriptions).
• Determining what equipment is available
  in a shop.
   – Allows MIS systems to take JDF Intent and determine
     production steps to produce job.
• Creating a UI to allow configuration of job
  processing for a piece of equipment or
  application.
• Preflighting a JDF before processing
  by a JDF consumer.
               What about PPDs?

PPDs (PostScript Printer Driver)
• Provide basic capabilities information
  about a printer
• Allow printer options to be configured by specifying
  PostScript snippets
• Provide a simple constraints mechanism for UI
• Allow controls to be localized
  (but typically just for the “advanced” dialog)
       What about XML Schemas?

XML Schemas
• Describe the aggregated capabilities of JDF
  (processes, resources, ResourceLinks, …)
• Do not support constraints definitions
• Do not support localizations
• Do not allow a device to specify a subset
  of the aggregated capabilities
     So what are Capabilities?                    Remember,
                                               the schema only
                                                 specifies the
                                                  aggregated
                                                  capabilities
• XML-based                                         of JDF

  – Of course…
  – The capabilities description directly reflects the
    structure of the JDF itself.
• Constrains a device implementation against the
  schema
  – Either the JDF schema or an extension schema
  – Does not require the schema to be used to work
          Capabilities Theory

A Device is the “Thing” that executes one or more
  JDF Nodes

JDF Parameters are either.....
• independent of one another, or
• can be expressed as a list of allowed independent
  sets
– e.g. a Scanner can scan at 1000 dpi grayscale, or 500 dpi color
• May be further constrained by logical boolean
  expressions, e.g.:
– The Device can print Duplex
– The Device can print Transparencies
– Setting Duplex and Transparency at the same time is
  constrained
        Capabilities Theory

• Performance may be specified
   – Maximum +
   – Average
   – Depending on further Job parameters
• Allow specification of current and allowed
  capabilities
   – Current: What kind of Media is in the tray
   – Allowed: What kind of Media may be loaded in the tray
• Defines defaults
• Specifies User Interface Localization
Device Parameter Space


                       Area covered by device
                       capabilities

      Interoperability Conformance Specifications


• Define a set of Interoperability
  Conformance Specifications – ICS
  – The term “JDF Compliant” does not immediately
    imply that two arbitrary applications will
    communicate.
    • Sending RIP instructions to a Folding Machine is not
      useful…
  – Two applications that comply with a given ICS
    communicate in a meaningful and useful way.
  – Product Certification is based on ICS Compliance
     Why ICS ?

        ICS documents

• Provide the basis for certification
• Ensure that products MUST read
   / write / accept certain conditions
   – Interoperability between applications
• Limited functionality in the initial
  ICS versions
   – Additional functionality is optional but not certifiable
   – Multiple levels
   – More functionality will be added in future ICS versions
        Read – Write Conformance

• JDF Specification: Describes the valid cardinality of
  parameters in a JDF or JMF instance
• ICS: Specifies conformance requirements for an application
  or device

   – W: Must write. The application only conforms, if it always writes
     the parameter
   – W?: May Write. Not a Conformance requirement
   – W: Conditional write conformance. External conditions exist
     that require an application to write.
   – !W: Must NOT write. The application does not conform, if it
     writes the parameter.

   – R: Must read. The Information must be “parsed and
     appropriately processed”
   – R  : Conditional Read. Conditions exist that MAY require read
     support
   – R?: May Read. Not a Conformance requirement
• Default: R? / W?
