Claim 5
Independent Claim
207 words
A method for producing a data carrier having a picture theme throughout which a security pattern is disposed, comprising the steps of: (a) forming a line copy of a security pattern on a transparent sheet; (b) forming a negative image of said line copy of the security pattern on a second transparent sheet; the area of the negative image being symmetrically enlarged in said negative image compared to the area of the original security pattern, by overexposing said negative image utilizing the photographic method of contact copying; (c) forming a positive image of said enlarged negative image of step (b) on a transparent sheet; (d) employing the sheet of step (c) and a negative image of the picture theme on a transparent sheet to form a positive image of the picture theme interrupted by the structure of the enlarged negative security pattern, by the photographic method of contact copying; (e) producing printing platens from the sheet of step (a) and the positive image of step (d), and (f) sequentially employing said platens of step (e) for producing a data carrier on which the security pattern of step (a) is printed within the widened negative security pattern of the positive image of the picture theme of step (d).
