Abstract
Abstract Methods of imaging and printing are provided whereby a transparent self-supporting substrate is coated with a transparent abhesive polymer and an image formed by inking said polymer and simultaneously subjecting said polymer to electromagnetic radiation to reduce the cohesive force of said ink or increase the adhesive force so as to selectively deposit ink in image configuration on said adhesive polymer, and transferring said inked image to a receiver sheet.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
80 words
A method of printing which comprises: (a) providing a transparent self-supporting substrate, (b) applying a coating to said substrate of a transparent, abhesive polymer, (c) placing said abhesive coating in contact with an ink surface and simultaneously subjecting said abhesive coating and ink to activating electromagnetic radiation in image configuration, in an amount and for a time sufficient to selectively deposit ink in said image configuration on said abhesive coating, and (d) transferring said inked image to a receiver sheet.
Claim 2
Independent Claim
80 words
A method of printing which comprises: (a) providing a transparent self-supporting substrate, (b) applying a coating to said substrate of a transparent, abhesive polymer, (c) placing said abhesive coating in contact with an ink surface and simultaneously subjecting said abhesive coating and ink to activating electromagnetic radiation in image configuration, in an amount and for a time sufficient to selectively deposit ink in said image configuration on said abhesive coating, and (d) transferring said inked image to a receiver sheet.
Claim 3
Dependent Claim
15 words
The method of claim 1 wherein the abhesive polymer is formed of a silicone elastomer.
Claim 4
Dependent Claim
38 words
The method of claim 1 wherein the abhesive polymer is applied to a cylindrical substrate and the polymer and ink subjected to activating electromagnetic radiation by direction of a laser scan from the inner surface of said cylinder.
Claim 5
Dependent Claim
11 words
The method of claim 1 wherein a planar substrate is provided.
Claim 6
Dependent Claim
29 words
The method of claim 4 wherein an image transparency is placed between said substrate and said abhesive polymer and activating electromagnetic radiation applied to the underside of said substrate.
