What are guidelines, how do I prepare guidelines in my artwork?

It is helpful to use guidelines in your artwork for print-ready files. Guidelines such as the safe zone, the trimming zone, and the bleed help designate where your product will be trimmed, as well as help you keep important elements such as text and graphics away from the trimming margin. Please provide us with a bleed all around your artwork, and make sure to keep all critical elements such as text and graphics within the Safe Zone.
