The first two control features Rows and Columns determine the overall imposition layout by setting the number of rows and columns. The calculate automatically option chooses optimal values to fill the sheet maximally. Auto positions filling is also activated when activating the automatic number calculation. This option cannot be used when working with a booklet imposition and also if the sheet size is calculated automatically (Activating 'Calculate automatically' activates manual sheet size input). If there are many positions on the sheet the automatic calculation can be time-consuming.
In the next group of options you can select a One-sided or a Two-sided sheet. If you choose to work with a two-sided sheet two mirrored pages of the page will be made.
The following four options let you choose imposition type – N-UP, Cut & Stack, Booklet and Calendar.
Note: Visually, nothing has to change while switching to booklet imposition, but the option Page order from beginning/end in the Info palette becomes available, which is necessary to define the scheme of assignment for this imposition type. It is recommended to use Automatic positions filling enabled for booklet imposition
You can read more about these imposition types in the chapter Imposition Types. Red warning will be displayed for a booklet imposition if the number of positions is unsuitable for auto positions filling. If auto filling is disabled the warning will be orange.
Note: The following features are hidden in Auto mode, where they are always enabled.
Auto positions size – Calculates size of positions according to pages for imposition.
Auto positions filling – Fills the sheet with pages from left to right and from top down. Automatic filling depends on the number of positions for booklet impositions.
These features are only available in Expert mode: There are two buttons next to Auto positions filling: "1|2" and "1st". The button "1st" is only visible in Expert mode, button "1|2" is displayed only for one-sided sheet in Expert mode. In both Automatic and Expert modes the position where the first page is placed is defined automatically. In Expert mode it is possible to change the position for the first page by button “1st”. Clicking this button will change the pointer and the position for the first side can be selected. This position must be in a corner of the imposition (top left, top right, bottom left or bottom down), marked in red in the preview for 6 columns and 4 rows . In booklet imposition types, it is also possible to select the positions next to the corners (for example the second position in the first row etc.; to select these positions it is, of course, necessary to have at least 4 rows or columns) as shown in this picture . The position of the first page is selected by pointer . If is shown, it means that the position is already selected for the first page. By clicking this position again you can activate an Alternative direction of auto position filling: unlike the basic filling option, where positions are filled in rows first, in alternative direction of filling they are filled in columns first (for booklet/cross-fold mode the filling is somewhat different and depends on the number of rows and columns). For booklet impositions it is also possible to change the appearance of the automatic filling by rotating the selected position in a suitable direction. Alternative filling also depends on the number of rows and columns – if there is only one row, the alternative filling is the same as the basic filling. Button "1|2" is intended for automatic "Work & Turn" and "Work & Tumble" print in One-sided mode. This feature can be disabled, but it is always active in booklet mode.
Bind front and back side – Enabling this option makes sure that when placing a page to the front side a page for its back side will be placed accordingly (and vice versa).
Further sheets automatically – This option is usually enabled. When it is turned off only the first sheet of an imposition will be made and the remaining pages will not be imposed.
