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.
