Sheet autofill (F5 key) consists in filling the use of pages on the sheet - pages collected in the Imposition Pages Table, according to the settings in the window Sheet autofill. The condition for calling this window is loading at least one PDF-file into the Imposition Pages Table.
 The switch: MODE: PAGES IN TURN/PAGES IN STACK changes the way of filling in the sheet.
PAGES IN TURN: PDF pages are placed on the grid next to each other (e.g. page number 1 next to page 2 on the same sheet).
An example of arranging successively on sheets a PDF-file consisting of 27-pages on a uses' 3x3 grid.
MODE: PAGES IN STACK: PDF-pages are placed on the grid of the pages one below the other on the following sheets (e.g. page number 1 on the first sheet, page 2 on the same place, but on the second sheet)..
An example of arranging in stock a PDF-file consisting of 27-pages on a uses' 3x3 grid.
 element allowing to determine the number of repetitions of each page.
 a group of switches allowing to determine the initial use from which the filling of the sheet will start.
 switch specifying the direction of filling the sheet - rows or columns.
 a group of switches that specify the range of pages that the sheets are filled with - all, even or odd.
In the case of double-sided sheets: odd-numbered pages are placed on the odd side of the full sheet or the corresponding part of the blank sheet (left - for sheets folded by side mark or top - for sheets folded by front mark). Similarly, even pages: are placed on an even side of the whole press sheet of the corresponding part of an half press sheet.
 A switch that allows the installation of double-sided prints in a special situation in which even and odd pages are collected in separate PDF-files (OOOEEE).
The number of sheets that will be needed to fill all pages from the Imposition Pages Table is the quotient of the number of pages by the number of pages on the page with rounding up. (example: on a 3x3 sheet (9 pages) and 29 pages collected in the Table - the number of sheets will be 29/9 = 3th rest 2. Because the rest of the division is greater than 0, the number of sheets will be increased by one and will be equal to 4).
This means that some of the uses on the last sheet (when completing the pages in succession) will be free (unoccupied) or the last uses on the sheets will be free (when filling in the stock).
Sample 1: filling a one-sided sheet.
Sample 2: filling a double-sided whole press sheet by the side mark.
Sample 3: filling a double-sided whole press sheet by the side mark with even and odd pages gathered in different files.
