Bleed/Safe Area for Printing
A bleed is a printing industry term that simply means there is printing going right to the edge of the paper. Bleed is the area around a document that is beyond the trim line. If you intend to have your artwork go right to the edge of the sheet or commonly referred to as borderless prints, you must include bleed.
Bleed gives printers some allowance for trimming the edges off, to end up with the right size of print and to be able to "print edge-to-edge".
The trim line is where the document will be cut.
The safe zone also compensates for potential shifting. We encourage our customers to keep their text clear from the safe zone. It may run the risk of being cut off if the text is too close to the border.
