Abstract
Abstract Apparatus and methods for the three-dimensional screen printing of images onto pallet-supported articles allow more than one layer of ink to be printed upon an article to form a three-dimensional design. A pallet having a compressible substrate is described; the substrate compresses to receive previously printed image masses during subsequent printing steps. A screen having baffles may cooperate with the substrate. A screen comprising dimples in its article-contacting surface is provided, whereby previously printed images may be protected from screen contact during a printing operation. Multiple printing steps may be performed without intermediate drying steps.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
137 words
A screen printing apparatus comprising in combination: a printing pallet comprising a support material having a lower and an upper surface, a resilient compressible substrate having a lower surface and having a planar, soft, compressible upper surface, and an attachment means for holding said lower surface of said substrate onto said upper support surface; and, a printing screen comprising an expanse of material having at least one perforation therethrough, and further comprising baffle means attached to the lower surface of said expanse of material, said baffle means sized and located to effectively protect a previously printed raised image on the said pallet-supported article by contacting said article at points proximate to said raised image so as to deflect said image into said compressible substrate during a printing operation in which said screen is pressed against said article.
Claim 2
Dependent Claim
137 words
A screen printing apparatus comprising in combination: a printing pallet comprising a support material having a lower and an upper surface, a resilient compressible substrate having a lower surface and having a planar, soft, compressible upper surface, and an attachment means for holding said lower surface of said substrate onto said upper support surface; and, a printing screen comprising an expanse of material having at least one perforation therethrough, and further comprising baffle means attached to the lower surface of said expanse of material, said baffle means sized and located to effectively protect a previously printed raised image on the said pallet-supported article by contacting said article at points proximate to said raised image so as to deflect said image into said compressible substrate during a printing operation in which said screen is pressed against said article.
Claim 3
Dependent Claim
23 words
A screen printing apparatus according to claim 1 wherein said baffle means and said expanse of material comprise a single piece of material.
Claim 4
Dependent Claim
27 words
A screen printing apparatus according to claim 1 wherein said baffle means is removably attached to the lower surface of said material by a baffle attachment means.
Claim 5
Dependent Claim
48 words
A screen printing apparatus according to claim 3 wherein said baffle attachment means comprises: a groove in the lower surface of said material; and, a tongue protruding from said baffle means adapted to engage said groove so as to keep said baffle means securely fastened to said material.
Claim 6
Independent Claim
133 words
A method of printing a new image onto an article having thereupon a previously printed three-dimensional image, said method comprising the steps of: mounting said article upon a printing pallet, said pallet comprising a support mAterial having a lower and an upper surface, a resilient compressible substrate having a lower surface and having a planar, soft, compressible upper surface, and an attachment means for holding said lower surface of said substrate onto said upper support surface; positioning a printing screen above said pallet-supported article, said screen adapted to push said previously printed image into the substrate of said pallet during the printing operation; pressing said screen down to force said previously printed image into the substrate; pressing a printing medium into the perforations of said screen; and, lifting said screen from said article.
Claim 7
Independent Claim
133 words
A method of printing a new image onto an article having thereupon a previously printed three-dimensional image, said method comprising the steps of: mounting said article upon a printing pallet, said pallet comprising a support mAterial having a lower and an upper surface, a resilient compressible substrate having a lower surface and having a planar, soft, compressible upper surface, and an attachment means for holding said lower surface of said substrate onto said upper support surface; positioning a printing screen above said pallet-supported article, said screen adapted to push said previously printed image into the substrate of said pallet during the printing operation; pressing said screen down to force said previously printed image into the substrate; pressing a printing medium into the perforations of said screen; and, lifting said screen from said article.
Claim 8
Dependent Claim
85 words
A method of printing according to claim 5 in which said screen comprises baffle means located on the lower screen surface, said baffle means sized and located on said surface to protect said previously printed image from contact with said screen, wherein said screen is positioned over said article so that said baffles surround the image, and wherein during the pressing step said baffles press on said article at points proximate to said printed image so as to deflect said printed image into the substrate.
