  2. Today’s Agenda • Imposition in Job Planning • Stripping process (resource: StrippingParams) • JDF 1.3: extended for Pack&Labels • Imposition in Prepress • Imposition process (resource: Layout) • Imposition in Digital Printing • LayoutPreparation process (resource: LayoutPreparationsParams) • Prepress GrayBoxes

  3. Imposition in Job Planning

  4. Available machines Available materials Available people Capabilities Optimal plan Optimized production plan Customer Order

  5. Optimal Plan • Includes parameters related to • Printing (press, paper, work style) • Folding (folding scheme) • Binding and trimming (assembly method) • Largely determines the imposition, BUT • No exact positions (no creep, no bottling, …) • No press marks, slug lines

  16. Assembly • Perfect bound  “Gathering” (on a pile) • Saddlestitch  “Collecting” (on a saddle) • Mixed assembly is possible as well <Assembly ID="ASM200" Status="Available" Order="Collecting"/>

  23. Layout • Imposition parameters like work style, assembly, and binding are implicit • Positions are absolute • Marks are included • Flattened description: no difference between one 16-page signature and two 8-pages signatures on a sheet • NEW JDF 1.3: Layout is partitioned!!!

  24. LayCrImp ICS • From LayoutCreation tool to consumer of a fully populated Layout • Producers: standalone imposition tools or Stripping, LayoutPreparation devices • Consumers:prepress workflow, RIP,…

  25. Imposition in Digital Printing

  26. Imposition in digital printing • Generates an imposition Layout from high level parameters • Useful for digital printers with integrated prepress • Supports controls for specifying • Multi-up regular grid of page cells • Scaling and rotation of reader pages for page cell mapping • Single sided or perfected (head to head/foot) sheets • Auto generation of sheet marks and slug lines • Page distribution schemes for saddle, and perfect binding • Sequential cut block distribution (i.e. cut and stack post cards) • Control for vert, horiz, and stack wise distribution of cut blocks • Independent horiz/vert gutter spacing and creep compensation • Document and cut block step and repeat • VDP document ganging

  27. LayoutPreparationParams • NumberUp • Rows and columns of PageCells • PageDistributionScheme • Distribution of PageCells over NumberUp (Saddle, Perfect, Sequential) • PresentationDirection • Distribution of pages into NumberUp (FoldCatalog, XYZxyz) • Sides • OneSidedFront, OneSidedBackFlipX/Y, TwoSidedFlipX/Y • FinishingOrder • GatherFold, FoldGather, FoldCollect, Gather • StepRepeat

  28. LayoutPreparationsParams • ImageShift • InsertSheet • FitPolicy • PageCell • Border, Color

  29. GrayBoxes

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

  33. In/Out ImpositionPreparation • In • Stripping resources • If not available, operator intervention • selecting a template • recommended to give Instruction Comment • JDF 1.3 • reference to external template • Out • Completed Layout • References to Marks

  34. ImpositionPreparation Level 1 • Level 1 ImpositionPreparation Gray Box • Stripping is optional • BinderySignature: only FoldCatalog • StrippingParams: no SectionList • Assembly: no mixed assemblies • StripCellParams: only TrimSize is mandatory

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

  37. Summary

  38. Summary • Three imposition methods covering different needs • Stripping (MIS -> Prepress) • Layout (Imposition program -> RIP) • LayoutPreparation (Prepress -> Digital press) • Stripping is extended in JDF 1.3 for Packaging Step-and-Repeat
