This app generates 4-up page imposition diagrams without any page count limitations. Signatures can be imposed according the four major imposition methods:

1. Sheetwise for perfect or thread-sewn binding.
2. Sheetwise for saddle-stitching.
3. Work & Turn for perfect or thread-sewn binding.
4. Work & Turn for saddle-stitching.

Additionally, the app provides information for the folding machine operator as to which folding units and buckle plates have to be activated for a given signature imposition.
