Abstract
Abstract A representation of a copy form is displayed and an image pattern is projected onto the representation so that the light image pattern is identical with and overlies part of the copy form. A sensitized material is irradiated with actinic light in a pattern corresponding to the projected pattern. The positions of the projected and exposed patterns are adjusted to expose the entire copy form onto the sensitized material.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
102 words
A photocomposing machine comprising means for displaying a representation of a copy form, means to project a light image pattern onto the representation so that the light image pattern is identical with and overlies a part of the representation of the copy form, means to irradiate sensitized material with actinic light in a pattern corresponding to the pattern projected onto the representation to expose the sensitized material in accordance with the irradiated pattern, and means to adjust the positions of the projected and exposure patterns so that the whole representation is exposed on the sensitized material as a copy of the representation.
Claim 2
Dependent Claim
102 words
A photocomposing machine comprising means for displaying a representation of a copy form, means to project a light image pattern onto the representation so that the light image pattern is identical with and overlies a part of the representation of the copy form, means to irradiate sensitized material with actinic light in a pattern corresponding to the pattern projected onto the representation to expose the sensitized material in accordance with the irradiated pattern, and means to adjust the positions of the projected and exposure patterns so that the whole representation is exposed on the sensitized material as a copy of the representation.
Claim 3
Dependent Claim
53 words
A photocomposing machine according to claim 1 wherein said means to adjust includes a mirror which is movable into and out of the path of the projected light image whereby in one position the light is transmitted to form said representation and in another position the light is transmitted onto the sensitized material.
Claim 4
Dependent Claim
48 words
A photocomposing machine according to claim 1 wherein said representation is displayed onto a viewing screen and said means to project includes one lens system, said means to irradiate includes a second lens system, and said image of the line and text is projected onto said viewing screen.
Claim 5
Dependent Claim
18 words
A photocomposing machine according to claim 1 having retrieval mechanism to restore a former position of the representation.
Claim 6
Independent Claim
119 words
A method of exposing a sensitized material to prepare a printing plate comprising projecting a light pattern representing a copy form to reproduce an image of the copy form on a viewing screen, projecting an image of light in a pattern onto the viewing screen corresponding to a part of the image of the copy form, irradiating the said image of light onto sensitized material at positions corresponding to the irradiated pattern on the viewing screen to expose the sensitized material according to the irradiated pattern, and adjusting the positions of the patterns of light on the viewing screen and on the sensitized material whereby the sensitized material is exposed to correspoNd to the image of the copy form.
Claim 7
Independent Claim
119 words
A method of exposing a sensitized material to prepare a printing plate comprising projecting a light pattern representing a copy form to reproduce an image of the copy form on a viewing screen, projecting an image of light in a pattern onto the viewing screen corresponding to a part of the image of the copy form, irradiating the said image of light onto sensitized material at positions corresponding to the irradiated pattern on the viewing screen to expose the sensitized material according to the irradiated pattern, and adjusting the positions of the patterns of light on the viewing screen and on the sensitized material whereby the sensitized material is exposed to correspoNd to the image of the copy form.
