To plan the perfect print, you need to understand the basic requirements for printing
Bleed is a printing term that refers to printing that goes beyond the edge of the sheet after trimming. Failing to provide bleed and crop marks can result in finished pieces showing a thin piece of white on the edge. Bleed should be added to your final size.
Edge of the paper is where the physical paper ends after trimming away the bleed. Anything extending beyond this line will be trimmed away
Crossed lines placed at the corners of an image or a page to indicate where to trim it are known as crop marks. Crop marks are automatically applied with most design software programs.
Safe Text Area is the area 5-10mm inside the trim line or edge of the paper. No critical text or critical design elements should be placed outside this area for safety and cutting purposes
