Impositions & Templates
Imposition refers to how pages are laid out on a sheet of paper. PDFClerk either shows pages exactly as they are (Imposition = "None"), or it shows pages as they will be imposed onto sheets of paper according to the chosen imposition and sheet size settings. Before explaining further, the following examples show how a factory provided imposition template affects the layout of pages onto sheets:
Showing first page of a document as it was imported from the original PDF document. |
|
![]() |
The pages are shown in their original size and form, regardless of the current Page Setup settings. This is the recommended mode for editing the original pages (e.g. editing or modifying objects on the page). |
Showing first page of a document in a 2-up imposition. |
|
![]() |
… The size of the sheets is determined by a document setting and can be static, or dynamic according to the paper size chosen in Page Setup. Notice how two pages are combined onto a sheet side, and how the sheet is automatically rotated to maximise available space. |
Working in non-imposed mode is recommended for editing pages.
Impositions are laid out according to the settings in their template. Templates can be created and edited in the Impositions Editor. An imposition specifies how to position one or more pages onto each side of a sheet of paper. The paper is divided into rows and columns, which results in a number of slots on the sheet which can be filled with pages. The templates allow control over how the slots are sized and whether there is any gutter between them; over how the pages are distributed among the slots on the front and on the back side; over the creation of PDF display boxes (media, bleed, trim and art box); over the vertical orientation per row or column (flipping even and/or odd rows/columns); over creep; and over the initial size of the signatures.
