Imposition Pages Table

Files can be placed in the Imposition Pages Table in several ways:

  1. By using one of the two buttons to load the file (Open file for imposition). In the window used to select a file, you can select more than one file (using the Ctrl key and the left mouse button).
  2. By dragging files from one opened folder window to the second one. The next dragged files are added at the end of the table.
  3. By loading the first file with the 1st or the 2nd method and (after selecting the line) using the Insert file AFTER... command or Insert file BEFORE... command.

Loading files with a large number of pages can take a long time - the program must read the TrimBox parameters on each page. If all pages in the PDF-file are identical, you can skip the TrimBox reading procedure, which will significantly speed up the loading of pages to the Table. After loading the first few pages and pressing the SHIFT + ESC key, select the Skip option. The program will accept the parameters read from the first page for odd pages, from the second page for even pages.

The selected rows can also be moved in the table (up-down) using the arrows on the ENABLED numeric keypad and holding down the F9 key!


Imposition pages table is separate for the leaflets imposition mode and book imposition mode. His task is to create a virtual document consisting of - one or several - real PDF documents. In the imposition mode, the page selection used in the imposition is made by the user, and the book imposition mode - the imposition involves all pages from all files shown in the table.

Columns’ symbols:

  • P – the page of "virtual" PDF, which is a combination of all loaded files.
  • PPDF – the real number of PDF page placed on the list.
  • File name – name of the PDF placed in the table. The full path can be seen in the status bar (at the bottom of the program window) after selecting one of the lines belonging to the given file.
  • Width, Height – recognized dimensions of the TrimBox area of the PDF-page.

The color in the P column means that the page marked this way has not yet been placed on the grid. Text color other than black in the column Width and Height means, that recognized dimensions differ from the fixed use’s size. The indication of whether a page from a given table row is placed on one of the grids used for one of the sheets is independent for the imposition mode of the leaflet and book imposition mode. The summary (below the table) is also different for each mode.


In book imposition mode, a text color other than black can also be seen in the PPDF column. Its presence (and alignment of the actual page number to the right) means a parity conflict between the virtual page number and the actual page number. In the example below - the file.pdf has an odd number of pages (3), which means that the pages in the next file in the list have a parity conflict.

Red in the last column means, that the program didn’t recognize the PDF-file placed in this row as compatible with the PDF/X (PDF/X-1 or PDF/X-3) standard. Green in this column means, that the PDF-file meets the requirements of the industry standard PDF/X.


To manage the content of the table of pages to imposition, use the right mouse button after selecting one or more rows.

  • Correct the recognizes dimensions... opens a dialog field that allows you to adjust the recognized TrimBox size. The window can also be called by double clicking on the selected row.
  • Change to other page of the file... allows you to replace the selected page with another one in the indicated file.
  • Change all the rows with the file... for... allows you to replace all lines with the selected file to another one. Rows in which the page number is larger than the number of pages in the new file will not be exchanged.
  • Set use’s sizes equal to the sizes of the selected page causes the set size of the use to be changed to equal the size of the TrimBox of the selected page.
  • Open the file in a PDF-reader... opens the file in the default PDF-browser.
  • Select... opens a submenu to select rows included or not included in the imposition, even or odd, and all.
  • Invert the selection selects the rows marked as unchecked and vice versa.
  • Save selected rows to file... creates a PDF-file on the disk that is a combination of all the pages selected in the table. The options are:
    • TrimBox and MediaBox – without changes (oryginal): the original page sizes and parameters of the TrimBox area are saved.
    • TrimBox unchanged + bleed 0 mm and TrimBox unchanged + bleed 3 mm: TrimBox like on the original page. MediaBox equal to TrimBox or increased by 3 mm on each side.
    • TrimBox with correction + bleed 0 mm and TrimBox with correction + bleed 3 mm: TrimBox equal to the area defined in the process Correct the recognizes dimensions. MediaBox equal to TrimBox or increased by 3 mm on each side.
  • Delete... opens the submenu for deleting from the table:
    • marked row (Delete selected rows (pages));
    • from the file, where the marked page can be found (Delete all the rows with file...);
    • blank pages (Delete all added blank pages) inserted using commends from the Insert... group. Vacancies that are actual PDF-pages are not deleted. The program is not able to check whether the PDF-page contains any objects or not.
  • Insert... opens a doceument using following commands: Insert the blank page BEFORE..., Insert the blank page HERE (clear the row), Insert the blank page AFTER... – that, insert blank rows in the right place in relation to the selected row. The other commands are: Insert the file BEFORE and Insert the file AFTER – refer to the marked row. Of course, it's about PDF-files. Inserting a file after the last row in the table can also be done by dragging the PDF- file to the open program window.
  • Convert selected pages... – this command allows you to isolate the selected page from a multi-pages PDF-file, convert it, save it to the disk and load the page to the Imposition Pages Table - in the place of the selected one.
  • Move... calls the submenu to move the selected row one Table up or down.
  • Duplicate... causes the duplication of the selected row specified (in a separate window) the number of times below the selected row.
  • Set the size of the use to the largest width and height in the table causes a change of the use’s size equal to the largest width and height found in the table.
  • Find the first sheet with this page causes move to the sheet where the page in the selected row was placed for the first time.
  • Copy, Cut, Paste – they allow you to change the position of the row in the table, its duplication or deletion.
  • Autofill (key F5) (only leaflet’s imposition) – working of this command varies, depending on the type of sheet selected (one-sided / two-sided). Automatic filling in the use is (in the case of two-sided prints) placing on the first page of the first full sheet (or on the corresponding part of an incomplete sheet) - the odd rows from the Imposition Pages Tabel. On the corresponding "falling" uses on the second page or the second part of the sheet, there are even rows with numbers one larger than those already placed in the odd rows. All utilities are occupied. Utilities are being overwritten. More in chapter Sheet’s autofill.
  • Filling according to the pattern (first sheet) – only leaflet’s imposition: the command allows to automatically perform a series of impositions in such a way that after generating the first sheet, the pages placed on it are removed from the list of files / pages to be impositioned. The pages occupied with these pages are filled with pages that "jump" in their place - and then another sheet is generated. This sequence is repeated until the Imposition Pages Tabel is completely cleared. More in chapter Filling according to the pattern.


Loading PDF-files with pages rotated using the PDF-browser

Pages rotated using the PDF browser are not really rotated, the PDF browser for the pages rotated with it only adds a marker, informing the browser that it should display pages rotated by the given rotation angle. However, the coordinates of objects on the page remain unchanged.

An attempt to load such PDF into Impozycjoner program will display a message about the presence of such rotated pages in the file and the loading of the file will be interrupted. In this case - before loading the file to the Pages Imposition Tabel or during loading - add the "real" turnover to selected pages. The program will create a new file on the disk, with the phrase "--RT" added to the original file name (an existing file with that name will be overwritten), and the loaded PDF file will be replaced with a new file.

We suggest that you choose not to rotate pages in the PDF browser and rotate the pages (if necessary) in the Rotate pages module before loading the Pages Imposition Table.
