The printed area which extends off the
trimmed area.
It is not possible to print all the
way to the edge of a sheet of paper or disc. To achieve
this effect, it is necessary to print a larger area than
is required and then trim the paper down. When producing
discs, the bleed will ensure your artwork sits in the print
templates correctly and attains the maximum print area possible,
leaving no white marks. Typically a designer would allow
an extra 3mm of bleed to allow for a little leeway when
trimming.
