Abstract

Abstract A support of paper or the like is imprinted with a security micropattern which prevents falsification of documents printed on the support by use of high resolution copier machines. The security micropattern is printed with ink which is transparent or of the same coloration as the support. The ink comprising the micropattern is either non-absorbent or hydrophilic, and the ink used for inscribing on the support is either hydrophilic or non-absorbent, respectively.

Claim 3
Dependent Claim 21 words
The security support according to claim 1, wherein said non-absorbent ink is one of an oil-based ink and a grease-based ink.
Claim 4

Claim 5
Dependent Claim 32 words
The security support according to claim 1, wherein the impression of the micropattern is of a positive type, wherein the ink which imprints the micropattern defines the figures that comprise such micropattern.
Claim 6
Dependent Claim 32 words
The security support according to claim 1, wherein the imprinting of the micropattern is of a negative type, wherein the ink which imprints the micropattern defines the background that comprises such micropattern.
Claim 7
Dependent Claim 44 words
The security support according to claim 1, wherein the distances between two adjacent lines or points that form each figure of the micropattern are smaller than 0.042 mm for preventing copying by copy machines with a maximum resolution of 600 dpi (dots per inch).
Claim 8
Dependent Claim 22 words
The security support according to claim 1, wherein the imprinting with said non-absorbent ink includes imprinting a document itself to be secured.
Claim 9
Dependent Claim 39 words
The security support according to claim 1, wherein each figure of the micropattern appears as anything but a blot when viewed with a magnification device, and, in a photocopy, each figure in the micropattern will appear as a blot.
Claim 10
Dependent Claim 97 words
A security support comprising: a) a base support which can be imprinted; b) a micropattern formed by hydrophilous ink, said micropattern including an arrangement of figures on a background imprinted on said base support, each of the figures of the micropattern being smaller than a maximum resolution power of a high-resolution copying machine; the security support with said micropattern operable to receive imprinting of an image to be secured with a non-absorbent ink, said figures of said micropattern being legible where the security support has been imprinted with said non-absorbent ink forming the image to be secured.
Claim 11
Dependent Claim 97 words
A security support comprising: a) a base support which can be imprinted; b) a micropattern formed by hydrophilous ink, said micropattern including an arrangement of figures on a background imprinted on said base support, each of the figures of the micropattern being smaller than a maximum resolution power of a high-resolution copying machine; the security support with said micropattern operable to receive imprinting of an image to be secured with a non-absorbent ink, said figures of said micropattern being legible where the security support has been imprinted with said non-absorbent ink forming the image to be secured.
Claim 12
Dependent Claim 22 words
The security support according to claim 9, wherein the imprinting with said hydrophilous ink includes imprinting a document itself to be secured.
Claim 13
Dependent Claim 21 words
The security support according to claim 9, wherein said non-absorbent ink is one of an oil-based ink and a grease-based ink.
Claim 14
Dependent Claim 15 words
The security support according to claim 9, wherein said hydrophilous ink is an alcohol-based ink.
Claim 15
Dependent Claim 32 words
The security support according to claims 9, wherein the impression of the micropattern is of a positive type, wherein the ink which imprints the micropattern defines the figures that comprise such micropattern.
Claim 16
Dependent Claim 32 words
The security support according to claim 9, wherein the imprinting of the micropattern is of a negative type, wherein the ink which imprints the micropattern defines the background that comprises such micropattern.
Claim 17
Dependent Claim 44 words
