NAME

PDF::Imposition::Schema4up - Imposition schema 4up (booklet)

SYNOPSIS

See PDF::Imposition.

SCHEMA EXPLANATION

This schema is basically the same (with the same options and features) of PDF::Imposition::Schema2up. But while with the 2up schema you get 2 logical pages on each physical page, with the 4up you get 4 pages on each side of the sheet. Hence, the signature must be a multiple of 8.

To actually use this schema, paper cutting is needed. First print recto-verso, then cut horizontally and put the lower stack on the upper one and proceed as you would with the 2up.

It's basically a shortcut to save paper if you impose, e.g. A6 on A4.
