etc.) should be kept inside this 1/4" margin. Anything left
outside this zone may be cut off or lost in the bind process.

BLEED
Extend the background images or colors 1/4" to the red dotted
box to add bleed. YOU MUST increase your page size to the bleed
size before saving as a .pdf. See our calculator above for bleed sizes.
