The final step in preparing the workspace is defining the live area of the page. Trim
size is the actual size of a page once it has been cut out of the press sheet. According
to your client, the magazine has a trim size of 8.5″ 1 11″.
Any elements that print right to the edge of a page (called bleeding) must actually
extend beyond the defined trim size. The bleed allowance is the amount of extra space
that should be included for these bleed objects. Most applications require at least a
1/8″ bleed allowance on any bleed edge.
Because of inherent variation in the mechanical printing and trimming
processes, most magazines also define a safe, or live area. All important design
elements (especially text) should stay within this live area. The live area for this
project is 8″ 1 10.5″.
