"Off-contact," for those who don't know, is the gap between the bottom of the screen and the substrate (the item being printed), its purpose is to improve printability during screen printing process. For screen printing plastics, paper, and t-shirts (as well as other

light weight apparel), the "thickness of a dime" is a good starting point for the off-contact gap. When you are printing thick apparel (like

sweatshirts) start with an off-contact gap of the "thickness of a nickel" and increase or decrease as necessary. The goal of off-contact

screen printing is to obtain a good "snap-off" when the squeegee passes over the stencil in the screen, resulting in a sharp printed image.
