Bleed is the printing that goes past the edge of where the sheet will be trimmed. It is the area to be trimmed off.
"Why do we need this?"
The bleed gives us a small amount of space to account for the movement of the paper when we are printing. Often in design, the artwork and background colours extend past the actual size of the printed piece. After trimming, the bleed ensures that there are no white edges showing on the final product.
It is difficult to print to the exact edge of a sheet of paper or card, so the bleed prints slightly larger than the area needed and it is then trimmed down to the exact size you want. Backgrounds, images and fills that you want to run to the edge of the page must extend past the trim line to give a bleed.
We require 1/4" bleed around the image.
