Abstract
Abstract A system for prestripping alignment of color separations providing automatic registration of same on stripping, includes provision for using a set of carrier-related holes in a first color separation for establishing position of the first color separation on a hole-transfer table, and then for using fiducial indicia on the first color separation to establish position of a sensor system which in turn is used in conjunction with corresponding fiducial indicia on each of the remaining color separations to establish location for corresponding carrier-related holes which are then punched in each color separation using the hole transfer table.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
197 words
A method for providing for pre-alignment of a plurality of color separations for stripping comprising: (a) photographically producing identical indicia on each of said plurality of color separations during the making of said color separation; (b) hole-keying a first color separation directly to a carrier using pre-set spacing of the holes by punching simultaneously through a portion of the first color separation and the carrier; (c) employing said pre-set spacing holes to locate the first color separation on a punch table by placing pins through said punched holes and into die holes in the punch table having said pre-set spacing; (d) indexing respective indicator means on said indicia in position clear of the first color separation and fixing in said position said respective indicator means; (e) substituting a second color separation in place of the first color separation by removing said pins and first color separation and locating the second color separation by indexing said indicia on the indicator means; and (f) punching holes in the second color separation on said pre-set spacing on said die table; thereby providing for pre-alignment for said plurality of color separations for stripping using said punched holes on said pre-set spacings.
Claim 2
Independent Claim

A method for providing for pre-alignment of a plurality of color separations for stripping comprising: (a) photographically producing identical indicia on each of said plurality of color separations during the making of said color separation; (b) hole-keying a first color separation directly to a carrier using pre-set spacing of the holes by punching simultaneously through a portion of the first color separation and the carrier; (c) employing said pre-set spacing holes to locate the first color separation on a punch table by placing pins through said punched holes and into die holes in the punch table having said pre-set spacing; (d) indexing respective indicator means on said indicia in position clear of the first color separation and fixing in said position said respective indicator means; (e) substituting a second color separation in place of the first color separation by removing said pins and first color separation and locating the second color separation by indexing said indicia on the indicator means; and (f) punching holes in the second color separation on said pre-set spacing on said die table; thereby providing for pre-alignment for said plurality of color separations for stripping using said punched holes on said pre-set spacings.
Claim 3
Dependent Claim
26 words
In a method as recited in claim 1, in step (c) said placing of pins being by placing of power punches fixed on said pre-set spacing.
Claim 4
Dependent Claim
21 words
In a method as recited in claim 2, said power punches being punches used for said punching holes in step (f).
Claim 5
Dependent Claim
87 words
In a system for producing pre-alignment holes for stripping in a plurality of color separations, a table, a bridge affixed to the table, a plurality of punches having detachable affixation to the bridge, means for aligning the plurality of punches respectively over selected holes of a row of holes in an end of the table; identical indicia on each of the plurality of color separations, and means for indexing on said identical indicia on each color separation and aligning each color separation with the plurality of punches.
Claim 6
Dependent Claim
87 words
In a system for producing pre-alignment holes for stripping in a plurality of color separations, a table, a bridge affixed to the table, a plurality of punches having detachable affixation to the bridge, means for aligning the plurality of punches respectively over selected holes of a row of holes in an end of the table; identical indicia on each of the plurality of color separations, and means for indexing on said identical indicia on each color separation and aligning each color separation with the plurality of punches.
