Abstract
A method of and printer for printing photographs on light-sensitive paper of a particular format from transparent masters on a roll of film by means of a projector. Both the film and a strip of the paper are advanced through a printing point. The paper is displaced across the direction the film travels in with the center of the prescribed paper format at a distance from the optical axis of the projector. The projector can be adjusted to project the image of the master larger or smaller than the paper format.
Claims16
A method of exposing transparent masters onto light-sensitive material in the form of individual sheets, wherein each sheet is positioned with respect to the exposure field in an image plane of an optical projection device such that the optical axis of the projection device passes next to the center of the sheet, said method comprising the steps of:
- (a) rotating the sheet by a prescribed angle about a first point in the image plane;
- and
- (b) rotating the sheet about a second point in the image plane.
In photographic printing apparatus for exposing transparent masters onto light sensitive material in the form of individual sheets with a positioning device for the light sensitive material, said positioning device causing a displacement of the sheet in two respectively perpendicular directions within the image plane of an optical imaging device, the improvement comprising (a) means for rotating the sheet and (b) control means, coupled to the rotating means, for rotating the sheet by a prescribed angle about a first point in the image plane and for rotating the sheet about a second point in the image plane.
