Abstract

Abstract Simulated stained glass panels are produced from a clear plastic sheet upon which are printed transparent colors in a desired pattern and simulated lead strips separating the various colored areas. A silk screen printing method is taught to achieve this result involving special inks and silk screen materials.

Claim 5
Dependent Claim 42 words

Claim 6
Dependent Claim 46 words
The product-by-process of claim 1 in which the appearance of leading is achieved by applying a thick viscous paint over the screen at least twice, to achieve a three-dimensional effect of lead by repeating the steps of the method at least once using the same screen.
Claim 7
Dependent Claim 142 words
A simulated stained glass panel made by the process of first creAting a transparent colored panel on a transparent plastic surface, and comprising the steps of: a. removing the electrical surface charge on a sheet of clear transparent plastic; b. placing a silk screen mesh over the surface of the plastic sheet and a mask over the screen; c. applying a dye ink having the desired color to the sheet through the mask and the screen; d. slowly removing the screen and the mask from the plastic, thereby leaving the plastic with the panels of color in the desired configuration; e. drying the dye ink thus applied; and f. repeating steps (b), (c), (d) and (e) using different colors of dye ink and different masks respectively corresponding thereto, whereby a transparent panel is produced having the desired configuration of colored transparent areas.
Claim 8
Dependent Claim 142 words
A simulated stained glass panel made by the process of first creAting a transparent colored panel on a transparent plastic surface, and comprising the steps of: a. removing the electrical surface charge on a sheet of clear transparent plastic; b. placing a silk screen mesh over the surface of the plastic sheet and a mask over the screen; c. applying a dye ink having the desired color to the sheet through the mask and the screen; d. slowly removing the screen and the mask from the plastic, thereby leaving the plastic with the panels of color in the desired configuration; e. drying the dye ink thus applied; and f. repeating steps (b), (c), (d) and (e) using different colors of dye ink and different masks respectively corresponding thereto, whereby a transparent panel is produced having the desired configuration of colored transparent areas.
Claim 9
Dependent Claim 49 words
The product-by-process of claim 6 in which the electrical charges on the surfaces of the sheet of clear plastic are removed by a thorough cleaning of all areas of the surface with a volatile solvent solution to prevent the formation of bubbles and other imperfections in the colored areas.
Claim 10
Dependent Claim 32 words
The product-by-process of claim 6 in which the desired colored dye ink is applied to the sheet by spreading the dye ink evenly and slowly by hand over the mask and screen.
Claim 11
Dependent Claim 28 words
The product-by-process of claim 6 in which the mask and screen are removed very slowly and evenly from the plastic after each application of a colored dye ink.
Claim 12
Dependent Claim 216 words
A simulated stained glass panel having colored areas on a plastic surface, separated by boundaries simulating leading made by the process comprising the steps of: a. removing the electrical surface charge on the sheet of clear plastic; b. placing a silk screen mesh over the surface of the plastic sheet and a mask over the screen; c. applying special colored transparent paint having the desired color to the sheet of plastic through the mask and screen; d. slowly and deliberately removing the screen and the mask from the plastic, thereby leaving the plastic with the areas of the desired color; e. repeating steps (b) and (c) using different colors and masks to create a panel having all of the required color areas; and f. creating a raised boundary pattern around the colored areas to simulate lead holding the stained glass in place, comprising the steps of: i. placing a coarse silk screen of a mesh size approximating the mesh size used to strain and clean batches of paint over the surface of the sheet of plastic; ii. placing a mask over the screen; iii. applying a thick viscous paint to the surface of the plastic sheet through the mask and screen; and iv. removing the screen and mask slowly and deliberately from the sheet of plastic.
