Which PDF boxes are used in a page programmed document?
The PDF boxes
A PDF page may include production-related content that falls outside the boundaries of the
finished page. The production-related content can be a bleed area, print marks, etc. To control
such content, a PDF page may contain as many as five separate boundaries:
• [Media box]
When you open a non-page programmed document in PRISMAprepare for the first time:
• PRISMAprepare uses the media box of each page to assign the media size for that page.
When the media size has been assigned, the media box is no longer actively used by
PRISMAprepare. The media box always exists and it is the largest PDF box.
• [Crop box]
The crop box may contain print marks, trim marks, color strips, etc in addition to the bleed area
and the page content. The print marks, etc are taken from the original PDF page.
• [Bleed box]
The bleed box may contain a bleed area in addition to the page content. Usually, the bleed
area is 3 to 5 mm larger than the trim box.
• [Trim box]
The size of the trimmed page. The trimmed page contains the page content. For each page, the
trim box is equal to the page size. In theory, the page size can be different for each PDF page.
• PRISMAprepare does not use the art box.
The trim box is always equal to the page size. The media box is not necessarily equal to the
media of the document. For example, for a booklet, PRISMAprepare imposes two pages on one
side of the media. Each page has its own media box which is not equal to the media of the
booklet.
