There are two different kinds of annotations in PDF Nomad 2:

Which kind of annotation to use depends on your needs. Some annotations do not have a counterpart of the other kind, but if they do, the matter is often one of whether it is important that the

Art Box

Defines the extent of a page’s meaningful content (including potential white space) as intended by the page’s creator.

Bleed Box

Defines the region to which the contents of the page should be clipped during the finishing process, such as extra bleed area to accommodate the physical limitations of cutting, folding, and trimming equipment. The page as printed may include finishing marks that fall outside the bleed box, and are cut off when trimmed.


In a folded (e.g. saddle stitched) booklet or signature the inner pages progressively extend (creep) further out than the outer pages. After trimming, the inner pages are narrower than the outer pages. If the pages were printed with static margins, then, after folding and trimming, the effective margins of the pages towards the center of the signature will progressively become narrower, and, if the signature is thick enough, the margins may even disappear, and some content may have been cut away during trimming.

Creep varies depending on the thickness of the paper and the number of pages in the signature. Creep is also known as thrust or push-out. Compensating for creep is also known as shingling.

Crop Box

Defines the region to which the contents of the page are to be clipped (cropped) when displayed or printed. Unlike the other boxes, the crop box has no defined meaning in terms intended use; it merely imposes clipping on the medium’s contents.


The amount of space added between the adjoining inner sides of two imposed source pages on the target sheet.


The superimposing of multiple pages onto a single sheet of paper.

Media Box

Defines the bounds of the physical medium on which the page is to be printed and the location the page (the contents) on that medium. A media box’s origin (left and bottom) is usually 0, 0, but it may be offset to adjust the alignment of the contents. Negative values will move the contents to the right and up; positive values will move the contents to the left and down.

Outlines (Bookmarks)

An outline consists of a tree- structured hierarchy of outline items (also known as bookmarks), which serves as a visual table of contents that displays a document’s structure while allowing quick access to other parts of the document. It is quite normal for a single outline item to simply be called outline.

Trim Box

Defines the dimensions of the finished product after trimming. It may be smaller than the media box to allow for production-related content, such as trim and registration marks, color bars, etc.
