Adobe Acrobat must be run in order to work in the plug-in. After it is run we open the document we want to impose on a sheet and then run the Montax imposer plugin – either from the menu (Plugins/Montax Imposer) or by clicking the Montax icon on the Advanced Editing toolbar. The active document from Acrobat will be automatically loaded into Montax.
This behavior can be adjusted in Preferences. It is possible to set whether the last opened imposition should be loaded or the active document in Acrobat. Other documents can be loaded anytime either from the menu or by clicking the Import PDF button on the Main toolbar.
Right after installation, the plug-in runs in the Automatic mode, which is indicated by a pressed "A" button on the Main toolbar, so many imposition parameters will be calculated automatically. First, it is necessary to decide whether you need a one-sided or a two-sided sheet and choosing the desired option on the Imposition appearance palette. Of course, one-sided sheet is usually selected for a single sided printing, but can also be used for the "work and turn" print (when the same design is printed on both sides) or if the resulting imposition is symmetrical and the back side contains the same design as the front one – e.g. for business cards. If a two sided sheet is selected two mirrored sheets are created automatically – one for the front and one for the back.
The next step is to select an Imposition preset that fits your needs from the Imposition presets palette. The PDF document from Acrobat will automatically fill positions on your sheet. If you cannot find the preset you need it is really easy to select a similar one and then manually adjusting the number of rows and columns. Previews can be activated under the work area which results in seeing real pages instead of numbered rectangles at the cost of a slightly slower rendering.
If you want to fill the whole sheet with a single page, you can use the Page repetition palette and activating the "Fill all positions" option. This can only be used for a standard N-UP imposition, not for booklets, or Cut&Stack.
These Imposition types (Standard N-UP, Booklet, Cut & Stack, Calendar) are activated by selecting a preset imposition. If you do not work with a preset you can select the type you need yourself or change it at any time.
The Sheet size palette can be used to select the paper size you need or to have it calculated automatically according to the size of pages and the amount of rows/columns. If the size is set manually the option to calculate the rows/columns amount automatically comes in handy – it fills the sheet so that it contains as many positions as possible. This option, however, cannot be used for Booklet imposition type.
Scale can also be set – either in percentage or by using the "Fit", "Fill" or "NON-PROP Fill" options. When fit or fill is selected pages with a different size will be enlarged or reduced as needed.
Position sizes for pages will be calculated automatically just like the spaces between them (these are determined from bleed size – the margins of the PDF file which will later be cut). These gaps can also be set manually on the Info palette.
It is also very easy to use trim marks, registration marks and sheet descriptions!
Further options and adjustments can be enabled by turning Auto mode off using the "A" button on the Main toolbar. Options which were hidden and calculated automatically will be displayed. Imposition margin (the area for bleed and trim marks), position size, bleed size etc. can then be changed on the Info palette. Many more options will also be enabled – for example automatic sheet filling properties. You can then decide in which order (e.g. left-to-right / top-down) positions are filled or assign specific pages to specific positions.
