Printers cannot print right to the edge of a sheet of paper. To create that effect, the printer must use a sheet which is larger than the document size. The printer prints beyond the edge of the document size (1/16 inch which is 0.0625 inch), then cuts the paper down to the document size. No text should go beyond the recommended safety, or it may be cut off while the printed piece is being cut to size.
Most jobs we print require a 1/16” bleed over each edge. If your job requires die-cutting or is a booklet, a 1/8” bleed is required.
