Creep in a book can cause content to be trimmed due to pages pushing out when the sections are folded. You compensate for creep by progressively shingling the page image areas towards the binding to decrease the page gutter or margin width, without affecting content. If you must maintain the gutter and margin widths, you can choose to progressively scale the images instead of shifting them.
The amount of creep in a book is affected by the number of folds and by paper thickness, and the affected pages depends on the binding style:
Note: References to Automatic Shingling in the Stock resources pane do not mean that shingling will be automatically applied to every job that uses that stock. Shingling or bottling will be automatically applied only if the Job has Auto Shingling enabled.
To additionally compensate for page skew that might be due to the number of pages, the thickness of the paper, or the folding equipment, you can apply Page Rotation (Bottling) in the template page properties. You can also override a product's shingling settings for specific template pages.
Configure the related settings on the Output tab in the Preferences dialog box as needed:
Scale shingled pages
Choose a default scaling type: Proportionally (retains the vertical and horizontal aspect ratio) or Anamorphically (Horizontally) (changes the vertical and horizontal ratios)
Determine the amount of shingling to apply, using either the approximate formula or exact method.
Tip: The value of stock thickness is measured in microns. Use a micrometer or obtain the thickness from the paper supplier.
|Approximate formula|| (number of sheets/4) x stock thickness The value that you use for the number of sheets depends on the binding type. If perfect bound, it is the pages per section. If saddle-stitched, it is pages per product or part.|
To apply your calculations, select Job > Layout Details .
Note: You can also set or adjust the shingling values in the Part Properties pane. This will allow you to set different shingling values for each part of a product.
