Abstract
Abstract A substrate, such as a banknote or travellers' check, carries a security device including in association at least one embossed transitory image, such as a latent or transient image and an embossed linear area. The arrangement is such that when the embossed region of the substrate is viewed from different angles each image and linear area can be visually discerned.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
45 words
A method of providing a security device on a region of a substrate, the method comprising blind embossing the substrate with at least one transitory image, and with a non-transitory linear area which is visible when the device is examined from substantially all viewing angles.
Claim 2
Independent Claim
45 words
A method of providing a security device on a region of a substrate, the method comprising blind embossing the substrate with at least one transitory image, and with a non-transitory linear area which is visible when the device is examined from substantially all viewing angles.
Claim 3
Dependent Claim
18 words
A method according to claim 1, wherein the blind embossing is carried out using an un-inked intaglio plate.
Claim 4
Dependent Claim
20 words
A method according to claim 2, wherein other parts of the substrate are intaglio printed simultaneously with the blind embossing.
Claim 5
Dependent Claim
24 words
A method according to claim 1, wherein the area of the substrate to be blind embossed is preprinted with an ink by offset lithography.
Claim 6
Dependent Claim
36 words
A substrate carrying a security device comprising in association at least one blind embossed transitory image, and a blind embossed non-transitory linear area which is visible when the device is examined from substantially all viewing angles.
Claim 7
Dependent Claim
36 words
A substrate carrying a security device comprising in association at least one blind embossed transitory image, and a blind embossed non-transitory linear area which is visible when the device is examined from substantially all viewing angles.
Claim 8
Dependent Claim
20 words
A substrate according to claim 5, wherein the linear area at least partly borders the at least one transitory image.
Claim 9
Dependent Claim
36 words
A substrate according to claim 6, wherein the transitory image comprises a latent image, and wherein the linear area defines a shape which is visible from all angles at which the latent image is not visible.
Claim 10
Dependent Claim
19 words
A substrate according to claim 6, wherein the linear area defines a perimeter line bordering the entire transitory image.
Claim 11
Dependent Claim
12 words
A substrate according to claim 5, wherein the linear area is continuous.
Claim 12
Dependent Claim
12 words
A substrate according to claim 5, wherein the linear area is curved.
Claim 13
Dependent Claim
20 words
A substrate according to claim 5, wherein the linear area is defined by a number of substantially parallel embossed lines.
Claim 14
Dependent Claim
18 words
A substrate according to claim 11, wherein the lines extend transversely to the length of the linear area.
Claim 15
Dependent Claim
17 words
A substrate according to claim 5, wherein the thickness of the linear area varies along its length.
Claim 16
Dependent Claim
13 words
A substrate according to claim 5, comprising a number of embossed linear areas.
Claim 17
Dependent Claim
32 words
A substrate according to claim 5, wherein the linear area is embossed to a depth at least equal to the shallowest depth to which the at least one transitory image is embossed.
Claim 18
Dependent Claim
17 words
A substrate according to claim 5, wherein the at least one transitory image is a transient image.
Claim 19
Dependent Claim
18 words
A substrate according to claim 5, wherein the security device includes a transient image and a latent image.
Claim 20
Dependent Claim
14 words
A substrate according to claim 17, wherein the images are superimposed on each other.
Claim 21
Dependent Claim
12 words
A substrate according to claim 5, wherein the substrate is specularly reflecting.
Claim 22
Dependent Claim
13 words
A substrate according to claim 5, wherein the substrate carries a metallic ink.
Claim 23
Dependent Claim
12 words
A substrate according to claim 5, wherein the substrate carries rainbow printing.
Claim 24
Dependent Claim
12 words
A substrate according to claim 21, wherein the rainbow printing is metallic.
Claim 25
Dependent Claim
15 words
A substrate according to claim 5, wherein the substrate comprises a banknote or traveller's check.
Claim 26
Dependent Claim
17 words
A substrate according to claim 5, wherein the linear area defines one part of the security device.
