Equivalent variants

Each ganging-imposition is subdivided into strokes. Each stroke, on its turn, is subdivided into shelves, comparable with the shelves of a book-case.  Each shelve contains an  MxN-arrangement of replicas from one specific order.

Subdivision into strokes and shelves

Subdivision into strokes and shelves

This logic permits the easy generation thousands of variants that are, from the combinatorial point of view, completely equivalent. Indeed, one can easily make the following adaptions to each imposition:

  1. Change the sequence of the strokes
  2. Change the sequence of the shelves within a stroke
  3. Rotate the replicas within a shelf 180 degrees.
  4. Center or align the elements within a shelf or within a stroke
  5. The content may also be turned recto/verso

Equivalent variants

These properties can be used to make changes , to ensure the colours are optimised for the printing process. These corrections belong to the pre-press-process. Yet our ganging engine will not generate equivalent variants. Only the best solution is presented in a standard format.
