METHOD OF ALIGNING A STAMP TO A STAMP BACKING PLATE
A method of aligning a stamp to a stamp backing plate includes mounting a fixture with a first alignment feature to a platen; providing a first stamp with a second alignment feature which matches the first alignment feature; aligning the first stamp to the fixture using the first and second alignment features; transferring the first stamp from the fixture to a first stamp backing plate maintaining registration; providing a second stamp with a third alignment feature which matches the first alignment feature; aligning the second stamp to the fixture using the first and third alignment features; and transferring the second stamp from the fixture to a second stamp backing plate maintaining registration.
1 . A method of aligning a stamp to a stamp backing plate comprising:
mounting a fixture with a first alignment feature to a platen;
providing a first stamp with a second alignment feature which matches the first alignment feature;
aligning the first stamp to the fixture using the first and second alignment features;
transferring the first stamp from the fixture to a first stamp backing plate maintaining registration;
providing a second stamp with a third alignment feature which matches the first alignment feature;
aligning the second stamp to the fixture using the first and third alignment features; and
transferring the second stamp from the fixture to a second stamp backing plate maintaining registration.
2 . The method of claim 1 wherein the first alignment feature is selected from a group consisting of a wire, a bar, and combinations thereof.
3 . The method of claim 1 wherein the second and third alignment features are selected from a group consisting of a notch, a reverse line, a line, an edge, a series of lines and a combination thereof.
4 . The method of claim 1 wherein the first stamp has a raised surface containing an image and the second alignment feature; and
the second stamp has a raised surface containing an image and the third alignment feature.
5 . The method of claim 4 wherein the raised images and the alignment features are in register.
6 . The method of claim 1 wherein the first stamp mounted on the first stamp backing plate is in a first stamp printing station; and
the second stamp mounted on the second stamp backing plate is in a second stamp printing station.
7 . The method of claim 6 wherein the first stamp mounted on the first stamp backing plate in a first stamp printing station prints a first image onto a receiver; and
the second stamp mounted on the second stamp backing plate in the second stamp printing station prints a second image in register to the first image onto the receiver.
8 . The method of claim 7 wherein the receiver is selected from a group consisting of paper, plastic, silicon, glass, metal, semiconductor, metalized film, film, ceramic and combinations thereof.
9 . The method of claim 7 wherein the printed receiver is a printed functional receiver.
10 . The method of claim 9 wherein the printed functional receiver is selected from a group consisting of a an electronic device, a memory, a conductive device, a light emitting device, a light detector device, a diode junction, a capacitive device, a strain detector, a stress detector, a mechanical device, a three dimensional object, a multi-colored graphic image and combinations thereof.
