The Marks section lets you add printed marks to your output sheets — fold lines, crop marks, staple positions, and more. These are guides to help you cut, fold, and assemble your finished product.
The left side of the view shows a zoomable preview of the marks on the sheet; the right side has the settings for each mark type. Each mark type has a checkbox to enable or disable it. When enabled, its settings appear below. Some mark types are only available for certain imposition types.
Lines that show you where to fold the paper.
Fold marks are usually placed outside the trim. Obviously if you are not trimming the paper, that won’t be possible.
Marks at the centre of the sheet, useful for alignment.
Corner marks that show where to trim the paper.
Most imposition types have just one trim region. However some (such as multi-up booklet) have multiple trim regions on the same sheet.
A line showing where to cut the sheet. Only available for the 8-page zine imposition type. By the nature of this cut mark, it will appear on your document.
A border drawn around the trim area.
Usually this isn’t desired. If you’re trimming to a specific location, and there’s a line drawn there, then any slight error in cutting may result in the line being visible on the finished page. However, if you are trimming by hand with a pair of scissors, this might be the lesser of two evils, and avoid you accidentally straying off course!
Marks showing where to staple. Only available for saddle-stitch and multi-signature imposition types.
Marks showing where to punch holes for binding. Only available for the comb binding imposition type.
The hole punch marks will match the locations of the holes as set in the Imposition Type screen.
The Show Margins checkbox (located underneath the preview) toggles whether trim and source margins are shown (as coloured dotted lines) on the preview. The margins can be useful to see where your pages will be placed, but you might want to hide them in order to see your printer’s marks without any distractions.
