– JDF 1.3: extended for Pack&Labels

• Imposition in Prepress

• Imposition in Digital Printing

– LayoutPreparation process (resource:

Page 5: Imposition in JDF Francis Labaere Co-chair O&P Esko-Graphics.

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

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"/>

Page 23: Imposition in JDF Francis Labaere Co-chair O&P Esko-Graphics.

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!!!

Page 24: Imposition in JDF Francis Labaere Co-chair O&P Esko-Graphics.

LayCrImp ICS

• From LayoutCreation tool to consumer of a fully populated Layout

• Producers: standalone imposition tools or Stripping, LayoutPreparation devices

• Consumers:prepress workflow, RIP,…

Page 25: Imposition in JDF Francis Labaere Co-chair O&P Esko-Graphics.

Imposition in Digital Printing

Page 26: Imposition in JDF Francis Labaere Co-chair O&P Esko-Graphics.

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

Page 27: Imposition in JDF Francis Labaere Co-chair O&P Esko-Graphics.

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

Summary

Page 38: Imposition in JDF Francis Labaere Co-chair O&P Esko-Graphics.

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
