<p>A direct screen printing method and apparatus includes one or a plurality of machines for printing indicia in single or multiple colors on a substrate, such as a cap (C) or a T-shirt. The method involves forcing ink (91) in the form of a viscous composition under constant gas pressure through a pattern in a screen (64) in contact with the substrate. The apparatus includes a holder (18) to support the substrate, height adjustable post (16) for providing the contact between the screen and the substrate, and pressure hose (80) for supplying gas to the ink (91) for a time and at a pressure appropriate to force the ink through the screen pattern to form a non-distorted detailed design on the substrate; in a preferred embodiment, the apparatus includes a screen print assembly including a replaceable screen holder (52), pressure hose (80) for introducing air under constant pressure to screen holder (52), and support members (84) on screen holder (52) for mounting a sensitized screen (64), especially a curved screen (64), upon which viscous ink (91) can be placed; and support (18) for mounting a substrate (C) for printing thereon by contacting screen (64) to the substrate (C) and introducing air under pressure to holder (52) to force said ink (91) through said sensitized screen (64) to print indicia on said substrate (C).</p> |
