Bleed is a printers description for the area around the edges of artwork where colour cannot be printed. Although mechnically operated, the cutting process is never 100% accurate, so to be safe, you should submit your artwork with an excess of 2.5mm each side. Further to this, it would be a good idea to place important text and images away from any printable edges.
