Claims
- 1. A method for the mounting of a one-color printing plate on a carrier sheet in a desired pattern corresponding to a one-color image desired to be printed on a recipient surface from the printing plate, which comprises:
- providing a small-scale representation of a substrate and a complete image to be printed thereon,
- providing printing plate elements for each color of said image to be printed on said substrate,
- enlarging and projecting said small-scale representation onto a printing plate element recipient surface to provide a full-scale projected representation of the substrate on said recipient surface,
- providing a template to determine which of said printing plate elements is intended to print which color on the printed substrate,
- attaching to said recipient surface the individual printing plate elements for a first color in the location(s) shown by said projected full-scale representation and the template, and
- repeating said attaching step to further recipient surfaces for the individual printing plate element(s) for each additional color of the image to be printed on the substrate,
- thereby providing a plurality of recipient surfaces each bearing the printing plate elements for the specific color to be printed by such elements.
- 2. The method of claim 1 wherein:
- said small representation is a small-scale single-color representation of the substrate, whereby said full-scale projected representation is a full-scale, single-color projected representation,
- said template is provided by providing a small-scale multiple-color representation of the substrate arm the complete multiple-color image is printed thereon, and
- the full-scale representation of the substrate and individual printing plate elements are compared with the small-scale multiple-color representation to determine the location of attachment to the recipient surface of the individual printing plate elements.
- 3. The method of claim 1 wherein:
- said small-scale representation is a small-scale multiple-color representation of the substrate, whereby the full-scale projected representation is a full-scale, multiple color projected representation, and
- said template is provided by said full-scale projected representation.
- 4. A printing plate mounting device, comprising:
- a small-scale representation of a substrate and a complete image to be printed thereon,
- a printing plate element recipient surface, and
- means for projecting said small-scale representation of a substrate and a complete image to be printed thereon onto said printing plate element recipient surface to provide on said recipient surface a full-scale representation of the substrate and the image to be printed thereon.
- 5. The device of claim 4 wherein said small-scale representation comprises a small-scale single-color representation of the substrate and image to be printed thereon.
- 6. The device of claim 4 wherein said small-scale representation comprises a small-scale multiple-color representation of the substrate and image to be printed thereon.
- 7. The device of claim 4 wherein said recipient surface comprises a carrier sheet.
- 8. The device of claim 7 wherein said recipient surface is supported on a horizontal raised surface.
- 9. The device of claim 8 wherein said horizontal raised surface has a flat metal bar extending between the lateral extremities onto which said carrier sheet is hooked and an upwardly-directed centering projection received in an opening in said carrier sheet to center the carrier sheet on the raised surface.
- 10. The device of claim 9 wherein said horizontal raised surface has a pair of parallel flat metal bars at the lateral extremities having aligned upwardly-directed projections and wherein the longitudinal ends of the flat metal bar has openings therethroughto receive a selected pair of said aligned upwardly-directed projections.
- 11. The device of claim 8 wherein said projecting means comprises a reflective surface spaced above said horizontal raised surface and an image forming and focussing means below said reflective surface and focussed thereon.
- 12. The device of claim 11 wherein said image forming and focussing means comprises a light source, a support surface for a transparent film bearing said small-scale single-color representation of the substrate operatively located with respect to said light source to permit light to pass through said transparent film and a focussing lens located in a downstream location with respect to said light source and effective to focus the image projected by said transparent film onto said reflective surface.
- 13. The device of claim 12 wherein said image forming and focussing means is mounted on vertically movable support means.
- 14. The device of claim 4 wherein said recipient surface is supported on a cylindrical surface and said cylindrical surface is arranged to be reciprocally-moved in a horizontal plane.
