9/312151

International Classification:

B05C 1706

US Classification:

101126

Abstract:

A system for accurately registering multiple silkscreens relative to a printing surface after they have been clamped into a silkscreen holder of a printing head of a rotary screen printing machine, and for accurate placement of an image on a framed silkscreen. A generally L-shaped registration device attached adjacent to one side of a pallet of the printing machine has first and second sides orthogonal relative to each other with a pair of gauges having visual displays positioned on the first side and a third gauge positioned on the second side. The gauges have outwardly biased plungers controlled by a lever to be simultaneously moved between a retracted positioned, a free-floating position and an engaged position relative to respective first and second sides of a silkscreen frame. The gauge displays allow the operator to take numerical readings to determine if, and how much, a frame has shifted from a zero setting after being clamped in the frame holder, which frame has shifted, to quickly re-register a frame to its previous setting, and to compensate for frames having misaligned images. Another aspect of the invention is an exposure frame for use in conjunction with the registration device having three contacts corresponding to the plunger positions of the registration device that engage a framed silkscreen during exposure of the image to create silkscreens having images aligned relative to the registration frame.

Abstract:

An improved method of printing with a machine having at least one printing head and at least one platen registerable therewith. The method may include the steps of placing an article on the platen, bringing the platen and article into registerable contact with a printing screen supported at the printing head and transferring ink through the printing screen to the article after which the platen and article are separated from the printing screen. The method is improved by additional steps of extending a heating element into the space and directing heat toward the platen to cure the ink printed thereon.
