The amount of Bleed directly affects printing costs and the Imposition process (sheet arrangement). While Bleed is essential to prevent registration errors and visible white edges after trimming, its exact size must be determined in coordination with the prepress department. This is because the Bleed amount increases the overall file dimensions by a few millimeters. When Nesting multiple copies onto a single print sheet, this dimension increase can potentially reduce the number of files that fit on the sheet. If fewer files fit per sheet, paper waste and printing costs significantly increase; therefore, determining the Bleed size must always consider economic factors.
