Screen printing is an alternate, less expensive way of decorating garments. Screen printing usually uses a woven mesh "screen" and forces ink through an ink block stencil. In cases when using screen printing you will feel the design on the substrate. The ink will fade, will wash out, and will cause the garment to be heavier than sublimation. Typically, screen printing price increases based on how many colors you use. In a nut shell, ink is laid down on a garment and then dried. It is very expensive and difficult to do customization, like last names, with screen printing. Screen printing can be done on cotton or poly, but be careful when using poly that your screen printer uses inks designed for poly and/or moisture control garments.
