Definition: To allow for deviations in cutting the paper to finished size an element that bleeds off the page is typically extended about 1/8" beyond the trim lines. The amount of bleed allowance may vary depending on the method of printing and the press used.
Slight movement of the paper on the press or movement during cutting could result in items that are supposed to bleed off the edge not quite reaching the edge -- leaving a bit of paper showing at the edges. Bleed allowance extends the image off the page a sufficient amount to counteract these slight deviations.
Elements that bleed off the page can sometimes add to the cost of printing if the printer must use a larger size of paper to accommodate the bleed allowance. To reduce costs, if possible redesign to eliminate the bleed or reduce the page size enough to fit the work on a smaller parent sheet of paper.
Pronunciation: [bleed uh-LOU-uhns]
