  1. Welcome Prepress Koen Van de Poel Chairman Origination&Prepress WG @ CIP4 Technology Staff @ AGFA

  2. Today’s Agenda • Introduction • Creating the Ticket • Gray Boxes • Extras • Processing • Output: Proofs, Plates, Ink key settings • JMF Messages • General: ICS, approvals

  3. Position Customer Print Manufacturing

  4. Creating the Ticket

  5. Life of a Job Ticket • First for estimating purpose • by CSR or estimator / or submitted • only details that have influence on cost are specified (no color names, no content) • If accepted, upgraded to production ticket • by production planner or CSR • more details added (final devices, scheduling) • Updated later with prepress details • color names, exact number of pages, content references

  6. MIS Estimating Production Planning Production Controller Press Controller Prepress Controller Legend Trapping ImageSetting Controller SW Device PlateSetterB ProoferA HW Device

  7. Known at Creation • Info available when MIS creates prod. ticket • administrative and job info • product nodes (part structure) and layout: binds info to sheets • imposition, number of pages • number of colors for each sheet side • processes: gray boxes

  8. Missing • Some info is often missing when the job is created because: • Content (PDF) arrives later • PDF is needed to extract Spot color names • Number of content pages for Cover often doesn't match description: 2 pages are combined in one

  9. Introduction to Prepress

  10. Steps in Prepress • Creative part • Prepress preparation (page level) • preparing content files ready to RIP • obtaining content files • preparing imposition • Production prepress (sheet level) • RIP • Proofs • Plate making and Preview for ink key

  11. PrePressPreparation Gray box ImpositionPreparation Gray box Plate Making Gray box Workflow

  12. Prepress Preparation • Goal: no errors or interactions in prepress production part (except mapping colors) • Steps for content (not in order) • obtaining content files (Asset Transfer) • conversion from native to standard formats • trapping • creating production quality standard formats • preflighting / fixing files • page proofs / approvals

  13. Imposition Preparation • Activities needed to create a description of where the pages and marks need to go on the sheet resulting in the Layout

  14. Production prepress • Controlled environment • nearly fixed processing times • few operator interventions/errors if well prepared • scheduling possible for plate making • Includes Imposition Proof • often needed before starting plate making • internal or external (takes extra time) approval

  15. Cover Body Black&White Color 2x 8 pp 16 pp Parts Prepress Product Brochure Prepress Process

  16. In and Outs • In • job ticket (+imposition info) • content files • Intermediate • Proofs (hard copy or soft proof) • Out • plates (film) • previews for ink key settings (ex PPF)

  17. Building a Workflow

  18. Gray Boxes • Easy way to let MIS define what prepress should do • PrePressPreparation, ImpositionPrepreparation • PlateMaking, xxProofing • MIS provides • input : available job info, more or less detailed • output: detailed info (sheet structure, plates, components) • Prepress operator (or defaults) will fill in remaining details

  20. PrePressPreparation Gray Box

  21. In/Out PrePressPreparation • In • indication of nr of pages • can be different from what prepress needs • Out • populated RunList

  22. Snippet Node <JDF Type="ProcessGroup" Types="PrePressPreparation" Category="PrePressPreparation" …"> <ResourceLinkPool> <RunListLink rRef="R0_I" ProcessUsage="Document" Usage="Input"/> <RunListLink rRef="R0_D" ProcessUsage="Document" Usage="Output"/> …>

  23. Snippet Input RunList <RunList Class="Parameter" ID="R0_I" Status="Available" NPage="6"/> <RunList Class="Parameter" ID="R0_D" Status="Incomplete"/>

  24. ImpositionPreparation Gray Box

  25. In/Out ImpositionPreparation • In • Stripping resources • If not available, operator intervention • selecting a template • recommended to give Instruction Comment • Future • reference to external template • Out • Completed Layout • References to Marks

  26. Stripping • High-level imposition related information from MIS to Prepress • avoids redoing imposition 3 times: • Estimating • Production planning • Prepress • allows bi-directional communication: prepress updating imposition info

  27. Sample: Stripping Sheet BinderySignature Pages / Cells <StrippingParams …> <BinderySignature FoldCatalog="F8-7"/> <Position RelativeBox="0 0 0.5 1"/><Position RelativeBox="0 0.5 1 1"/> </StrippingParams>

  29. Snippet Layout <Layout …"> <Signature Name="SIG1"> <Sheet Name="SHT1"> <Surface Side="Front"/> <Surface Side="Back"/> <MediaRef rRef="PAPMSVA_880x630"/> </Sheet> </Signature> <Signature Name="SIG2"> <Sheet Name="SHT2"> <Surface Side="Front"/> <MediaRef rRef="PAPMSVA_880x630"/> </Sheet> </Signature> </Layout>

  30. PlateMaking Gray Box

  31. In/Out Platemaking • In • Media (plate) • Colors • RunLists • document (content) • marks • Layout • Out • Ink key setting preview (PPF) • ExposedMedia (plate)
