Bleed is the area outside where your printed piece will be trimmed and will be discarded during the cutting process. It is needed when trimming large amounts of paper at once to have leeway around the edges to account for slight movement when cutting.
Please include .125″ bleed on all Offset or Digital jobs. Wide Format jobs require .25″ bleed. Please make sure that your crop marks are not showing inside the bleed area.
For Wide Format, do not include marks on contour cuts (not a quadrilateral shape) as files will be overlapping when printed multiple up to utilize the paper to its maximum potential.
