• The location of a fold is defined by a dotted line called a fold mark; similarly, the 

location of a cut is defined by a solid line called a trim mark. 

• Specialized marks also define the size and locations of margins (space surrounding 

the page’s content area), gutters (space between pages), and bleeds (extensions of 
content beyond a trim mark; used to ensure that printed area extends to the very 
edge of a trimmed page). 

DocBuilder Pro makes it easy to set up gutters and specify a set of printer’s marks to 
image on the finished sheet, as illustrated in the following figure.

A book layout must also adjust the placement of pages according to the total number 
of pages in the job. For example, a book is often composed of more pages than can be 
printed on a single sheet. When the number of pages in the book is a multiple of the 
number of pages on a sheet, the same layout plan is used to place pages on additional 
sheets until all of the pages in the book are printed. However, if the total page count is 
not an even multiple of the number of pages in the layout, one signature may be laid 
out to accommodate the discrepancy.
