  22. 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

  23. Imposition in Digital Printing

  24. 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

  25. 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

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

  27. Impositioning & MIS to Prepress ICS

  28. MIS to Prepress ICS From MIS Controller to Prepress Workflow Manager

  29. MIS to Prepress ICS • Level 1 ImpositionPreparation Gray Box • BinderySignature: only FoldCatalog • StrippingParams: no SectionList • Assembly: no mixed assemblies • StripCellParams: only TrimSize is mandatory

  30. Summary

  31. Summary • Three imposition methods covering different needs • Stripping (MIS -> Prepress) • Layout (Imposition program -> RIP) • LayoutPreparation (Prepress -> Digital press) • Open issues for “imposition” (aka step & repeat) for packaging
