Also known as digital sheet assembly. Arrange the individual pages of a print job within the print sheets in order to make optimum use of the paper format of the printing machine (see also print).

page numbers

Typical page numbers are 4, 8, 16 or 32 pages per printed sheet. The subsequent processing, such as folding, cutting and stitching or gluing must be taken into account.


The imposition scheme determines the layout of all pages on the print sheet and the folding pattern. This provides an overview of the number of printed and folded sheets. The so-called sheet signature is the numbering of the folded sheets so that the correct sequence can be checked during later collation. The signature is removed when the sheet is cut later.
