3 Imposition in Job Planning

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

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

6 JDF Stripping Stripping StrippingParams Assembly Layout RunList(Marks) RunList(Doc) High level (Optimal Plan) flattened

16 Assembly Perfect bound  “Gathering” (on a pile) Saddlestitch  “Collecting” (on a saddle) Mixed assembly is possible as well

17 Imposition in Prepress

18 JDF Imposition Imposition Layout RunList(Doc) RunList RunList(Marks) Imposed Surfaces Exact page and mark positions on the sheets

19 Layout Front

20 Layout Back

21 Layout

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 Impostion 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

27 Impositioning & MIS to Prepress ICS

28 ICS Level 1 ImpositionPreparation Gray Box –BinderySignature: FoldCatalog –StripCellParams: WorkStyle –Assembly (no mixed assemblies)

29 Summary

30 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
