Abstract

Abstract The present invention relates to graphic or like reproduction processes and is concerned with obtaining accurate registration between the number of sets of color components, particularly color separation components, with respect to a carrier sheet. In accordance with the invention and where there is a number of sets of color separation components, the components of each set are initially registered with respect to the carrier sheet and then two spaced registration holes are formed through each set of components and the carrier sheet in the same relative positions, whereupon the plurality of sets of components and the carrier sheet can be positioned in register by locating the now formed register holes over suitable register pins. The invention also relates to apparatus for carrying out this method and comprising a surface to receive the color components and the carrier sheet with means for holding the relative materials in proper relation to said surface: a drilling machine is also provided for making the register holes in the materials simultaneously, said machine being mounted so as to be capable of movement in 2* above the surface.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 113 words
In a graphic or like reproduction process, for effecting the registration of at least one set of color components with respect to at least one carrier sheet, the improvement which comprises initially registering the components of said at least one set with respect to said at least one carrier sheet on a supporting surface, drilling at least two spaced registration holes through said at least one set of components and said at least one carrier sheet while in the same relative positions on said surface, and positioning the at least one set and the at least one carrier sheet in register one with the other by locating said register holes over register pins.
Claim 2
Dependent Claim 113 words
In a graphic or like reproduction process, for effecting the registration of at least one set of color components with respect to at least one carrier sheet, the improvement which comprises initially registering the components of said at least one set with respect to said at least one carrier sheet on a supporting surface, drilling at least two spaced registration holes through said at least one set of components and said at least one carrier sheet while in the same relative positions on said surface, and positioning the at least one set and the at least one carrier sheet in register one with the other by locating said register holes over register pins.
Claim 3
Dependent Claim 35 words
A method as claimed in claim 1 in which each registration hole through said at least one set is drilled at the same time as the corresponding hole through said at least one carrier sheet.
Claim 4
Dependent Claim 33 words
A method according to claim 2 wherein the at least one set of color separation or other components is positioned on the at least one carrier sheet before formation of the registration holes.
Claim 5
Dependent Claim 24 words
A method according to claim 1 wherein the at least two spaced registration holes are formed with the assistance of an appropriately apertured jig.
Claim 6
Dependent Claim 52 words
A method as claimed in claim 1 utilizing a plurality of color sets and carrier sheets, in which the carrier sheets are provided with registering perforations near at least one edge and are retained in alignment with each other by pins projecting through said perforations while said registration holes are being drilled.
Claim 7
Dependent Claim 21 words
A method as claimed in claim 1 in which the cuttings resulting from said drilling are removed through the drill itself.
Claim 8
Dependent Claim 145 words
Apparatus for registering at least one set of color components with respect to at least one carrier sheet in a graphic reproduction process, said apparatus comprising a support having a translucent surface to receive said at least one set and said at least one carrier sheet, lighting means positioned beneath said surface to provide illumination thereof, holding means for securing said set and sheet in relation to said surface, and a rotary drilling machine for drilling holes in said set and sheet mounted to move with 2* of movement above said surface, said drilling machine comprising a hollow drill provided with a tip having a cutting edge, and at least one air hole spaced from said cutting edge, together with suction means connected to draw air and cuttings through said tip, away from said cutting edge, and out through said at least one air hole.
Claim 9
Dependent Claim 145 words
Apparatus for registering at least one set of color components with respect to at least one carrier sheet in a graphic reproduction process, said apparatus comprising a support having a translucent surface to receive said at least one set and said at least one carrier sheet, lighting means positioned beneath said surface to provide illumination thereof, holding means for securing said set and sheet in relation to said surface, and a rotary drilling machine for drilling holes in said set and sheet mounted to move with 2* of movement above said surface, said drilling machine comprising a hollow drill provided with a tip having a cutting edge, and at least one air hole spaced from said cutting edge, together with suction means connected to draw air and cuttings through said tip, away from said cutting edge, and out through said at least one air hole.
Claim 10
Dependent Claim 120 words
Apparatus for registering at least one set of color components with respect to at least one carrier sheet in a graphic reproduction process, said apparatus comprising a support having a translucent surface to receive said at least one set and said at least one carrier sheet, lighting means positioned beneath said surface to provide illumination thereof, holding means for securing said set and sheet in relation to said surface, and a rotary drilling machine for drilling holes in said set and sheet mounted to move with 2* of movement above said surface, said drilling machine comprising a hollow drill provided with a tip having a cutting edge and said translucent surface being made of a material softer than said drill.
Claim 11
Dependent Claim 120 words
Apparatus for registering at least one set of color components with respect to at least one carrier sheet in a graphic reproduction process, said apparatus comprising a support having a translucent surface to receive said at least one set and said at least one carrier sheet, lighting means positioned beneath said surface to provide illumination thereof, holding means for securing said set and sheet in relation to said surface, and a rotary drilling machine for drilling holes in said set and sheet mounted to move with 2* of movement above said surface, said drilling machine comprising a hollow drill provided with a tip having a cutting edge and said translucent surface being made of a material softer than said drill.
Claim 12
Dependent Claim 51 words
Apparatus as claimed in claim 8 in which said hollow drill is provided with at least one air hole spaced from said cutting edge, together with suction means connected to draw air and cuttings through said tip, away from said cutting edge, and out through said at least one air hole.
Claim 13
Dependent Claim 18 words
Apparatus as claimed in claim 8 in which said translucent surface is made of a synthetic plastic material.
