Horizontal Scale :  Scale value in percentages for placing the PDF page horizontally.

Vertical Scale :  Scale value in percentages for placing the PDF Link file vertically.

Symbolic page numbers will remain same on both modes. Use only right to left option when the first page of the PDF is the first page of a right to left reading book.

Left to Right (Default) :  Regular mode for making books in all left to right reading languages.

Right to Left (Arabic) :  Option for making books in Arabic, Hebrew or similar right to left reading languages.

Binding / Folding 

Binding Method :  Select the binding method of the Job.

• Section Starting Number :  Enter the starting section number for current layout.

Creep / Shingling :  Saddle stitched books with more pages require creeping to get the pages are aligned on the outer edge after cutting.

Creep Setup :  Opens Creep Setup window


Auto Gutters / Gaps : Apply new values to all gutters in the layout

Keep Default / Current Values :  No change in gap settings (default). The values in the vertical and Horizontal folding gaps are the default values from the Global Layout Preferences. 

Auto Distribute to Print Run Paper Size :  Keep all gaps in same size by distributing the folding gaps evenly on the specified print run paper size. This will ensure easy folding & binding on some automatic machines.

Apply New Values to all Gutters / Gaps :  Apply changed values to all vertical & horizontal gaps.


Binding / Routing Margin :  Use 0 for Saddle Stitch / Stapling jobs. For Perfect binding jobs, use the routing margin required for your binding machine. Included perfect binding templates use 6mm as routing margin. Check with your technical person for the exact values.

Gutter / Folding Gap Settings :  The values in the vertical and horizontal folding gaps are the default values from the preferences. Select ‘Apply New Values to all Folding Gaps‘ to apply new values to all vertical & horizontal values in the layout. ‘Auto Distribute to Print Run Paper Size’ is an option to keep all the folded pages in same size by distributing the folding gaps evenly on the specified print run paper size. This will ensure easy folding & binding on automatic machines.

Use main layout editor window to edit individual folding or routing gaps. Check the Edit Gaps section for more information.

Reset to Defaults :  Discard all individual pagination settings including page numbers gaps and marks etc. And reset the layout to defaults.


Note:  You can edit individual Binding Gap / Folding Gap / Routing Margin values. On the layout editor window, double click on the desired page gaps on layout preview to edit the ‘Vertical Folding Gap’ and ‘Horizontal Folding Gap’ between two adjacent pages. Select the ‘Change All’ check box to apply the new values to all corresponding folding gaps (Horizontal or Vertical) on the signature. Changes will apply to both sides if the layout contain two master signatures.
