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
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

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
