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

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