Abstract
Abstract An engraved image identification card has a translucent planar base member with a multiplicity of engraved scores extending into one of its surfaces with an opaque layer positioned adjacent either the engraved side of the translucent member or the non-engraved side of the translucent member opposite the engraved side to provide enhancement of the contrast between the engraved and non-engraved regions in the translucent member.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
117 words
A two-layer engraved identification card comprising: a translucent, single layer, planar member having a first major surface and a second major surface opposite the first major surface, the first major surface having an image engraved therein to define engraved regions and non engraved regions for generating an observed image on the translucent planar member the engraved regions being entirely contained in the translucent single layer planar member; and a non-engraved opaque planar member abutting directly against and covering one of the first and second major surfaces for enhancing the contrast between the non-engraved and the engraved regions whereby the observed image is more readily seen, the other of the first and second major surfaces being completely uncovered.
Claim 2
Dependent Claim
117 words
A two-layer engraved identification card comprising: a translucent, single layer, planar member having a first major surface and a second major surface opposite the first major surface, the first major surface having an image engraved therein to define engraved regions and non engraved regions for generating an observed image on the translucent planar member the engraved regions being entirely contained in the translucent single layer planar member; and a non-engraved opaque planar member abutting directly against and covering one of the first and second major surfaces for enhancing the contrast between the non-engraved and the engraved regions whereby the observed image is more readily seen, the other of the first and second major surfaces being completely uncovered.
Claim 3
Dependent Claim
19 words
The engraved identification card of claim 1 wherein the non-engraved opaque planar member is positioned over the first surface.
Claim 4
Dependent Claim
21 words
The engraved identification card of claims 1 or 2 wherein the engraved image is the mirror image of the observed image.
Claim 5
Dependent Claim
19 words
The engraved identification card of claim 1 wherein the non-engraved opaque planar member is positioned over the second surface.
Claim 6
Dependent Claim
24 words
The engraved identification card of claims 1, 2 or 4 wherein the non-engraved opaque planar member is permanently affixed to the translucent planar member.
Claim 7
Dependent Claim
21 words
The engraved identification card of claim 3 wherein the non-engraved opaque planar member is permanently affixed to the translucent planar member.
Claim 8
Dependent Claim
36 words
The engraved identification card of claim 5 further comprising an adhesive between the non-engraved opaque planar member and the translucent planar member for permanently affixing the non-engraved opaque planar member and the translucent planar member together.
