Nested Saddle binding joins two or more saddle booklets (called “subsets”) to form a larger booklet. The subsets are stacked along the common fold, or spine, for stitching or gluing after printing. In Nested Saddle booklets, creep is a factor.

Number of sheets in a subset (saddle) - Use this option to specify the number of sheets in each subset.

The following illustration shows Nested Saddle, left-edge binding imposition for a 16-page document with two sheets (equivalent to eight document pages) per subset:

1	Subset 1
2	Signature 2
3	Signature 1
4	Subset 2
5	Signature 4
6	Signature 3

The following illustration shows how the signatures of a 16-page Nested Saddle booklet are folded and the subsets grouped together. Subset 1 includes Signatures 1 and 2; Subset 2 includes Signatures 3 and 4:

1	Signature 1
2	Signature 2
3	Signature 3
4	Signature 4

The following illustration shows how the subsets are joined together along the common fold for the nested saddle, left-edge binding, booklet:
