Abstract
Abstract Method of constructing a large poster for a back-lighted signboard from a plurality of smaller poster sections including improving the translucent quality of the poster material, aligning respective adjacent sections for exact image continuity, laminating a clear film over a first poster layer, laminating a second poster layer over the clear film, and applying heat and pressure to create a composite laminated poster having registered images throughout.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
126 words
A method of constructing a large poster from a plurality of sheets containing image portions, for use on a back-lighted signboard, comprising the steps of (a) immersing the plurality of poster sheets in a solution of about 13% liquid silicone and about 87% mineral spirits, and removing the sheets from solution and drying them; (b) aligning a first group of adjacent image sheets in abutting image edge alignment; (c) overlaying the edge-aligned sheets with a clear film layer having adhesive surfaces (d) overlaying the clear film layer with a second group of matching image sheets and aligning said sheets in image registration with said first group of sheets; and (e) forming a laminated whole from said first group, said clear film layer, and said second group.
Claim 2
Independent Claim
126 words
A method of constructing a large poster from a plurality of sheets containing image portions, for use on a back-lighted signboard, comprising the steps of (a) immersing the plurality of poster sheets in a solution of about 13% liquid silicone and about 87% mineral spirits, and removing the sheets from solution and drying them; (b) aligning a first group of adjacent image sheets in abutting image edge alignment; (c) overlaying the edge-aligned sheets with a clear film layer having adhesive surfaces (d) overlaying the clear film layer with a second group of matching image sheets and aligning said sheets in image registration with said first group of sheets; and (e) forming a laminated whole from said first group, said clear film layer, and said second group.
Claim 3
Dependent Claim
18 words
The method of claim 1, wherein the step of immersing is done for at least about 8 hours.
Claim 4
Dependent Claim
29 words
The method of claim 2, wherein the step of drying said sheets further comprises heating said sheets to a temperature of about 175° F. for at least 3 hours.
Claim 5
Dependent Claim
29 words
The method of claim 1, wherein the step of forming a laminated whole further comprises heating and compressing said first group, said clear film layer, and said second group.
Claim 6
Dependent Claim
128 words
The method of claim 1, wherein the step of overlaying the edge aligned sheets with a clear film layer having adhesive surfaces comprises overlaying all except a narrow edge of said sheets, said sheets becoming a first plurality of sheets, and further comprising repeating steps a, b, and c for a second plurality of sheets, and placing said second plurality in edge abutting image alignment with said first plurality of sheets, and overlaying the respective narrow edges of said sheets not previously overlaid with a clear film layer having adhesive surfaces bridging said edge abutting sheets and intermediate said first and second group of matching image sheets, and forming a laminated whole from said first group, said clear film layer and said second group along said narrow edge.
