Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
59 words
Method of producing by means of a bi-level recording device (1) a composite record from visually distinguishable images wherein said individual images remain distinguishable characterised in that the recording device (1) is activated in dependence on the result of an EXOR operation (2) performed on the binary representations of said images (8, 9) that are at least partially superimposed.
Claim 2
Dependent Claim
61 words
Method according to claim 1 wherein said images are coloured or colour developable images and wherein said logical EXOR operation is calculated on at least one bit map of a colour separation record of each of said images so as to obtain the signals in correspondence of which a recording device is activated in order to produce a coloured composite record.
Claim 3
Independent Claim
21 words
A method according to any preceding claim, wherein the bi-level recording device directly creates a visible or a latent developable image.
Claim 4
Independent Claim
52 words
A method according to any preceding claim, wherein the record produced by means of the bi-level recording device comprises a half-tone image of a continuous tone subject and a visually distinct half-tone image of a uniform tone subject, one of such images being superimposed on or at least partly overlapping the other.
Claim 5
Independent Claim
17 words
A method according to any preceding claim, wherein said bi-level recording device is a bi-level printing device.
Claim 6
Independent Claim
20 words
A method according to any preceding claim, wherein said bi-level recording device is a device which image-wise exposes light-sensitive material.
Claim 7
Dependent Claim
76 words
Apparatus for producing a composite record from visually distinguishable images, said apparatus comprising a bi-level recording device (1) and comprising means (3,4,6,7) for generating binary signal representations of the images to be recorded, characterised in that the apparatus comprises means (2) to perform a logical EXOR operation on the binary signal representations of said images and which are connected to said recording device to cause activation thereof in dependence on the result of said EXOR operation.
Claim 8
Dependent Claim
72 words
Apparatus according to claim 7, wherein said recording device is a device for producing coloured or colour-developable images, said means for generating binary code signals is adapted to generate bit maps of the individual colour-separation records of coloured images to be recorded, and the apparatus comprises means for performing logical EXOR operations on at least one bit map of a colour separation record pertaining to each of the images to be recorded.
