If you are a creative individual, I'm pretty sure that you are always keeping an eye out for a good deal to be able to share your art in an effective way. So now, what exactly comprises a good deal? I would guess having more paper space to work with at a great price is a part of it.
All files must incorporate a 1/8" bleed on all four sides.
"Bleed" is a printing term used to indicate the area that will be trimmed off after the job is printed and cut down to the finished size. Since the bleed extends 1/8" all around the card, your document set-up should be 1/4" taller (1/8" on top and 1/8" on the bottom) and 1/4" wider (1/8" on the left and 1/8" on the right) than the finished size of the card. The chart below indicates what the document set-up should be for a particular finished size.
