Imposition in Job Planning

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

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

Imposition in Digital Printing

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
