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

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
