The printer measures the exact size of the paper and the desired margins. Then marks are made at both ends of the sheet of paper, and corresponding marks (usually in the shape of a "T") are made on the stone. Then the printer matches the marks on the paper to those on the stone.
The next problem was how to align the mask, as the system focussed only UV light. This was solved by adding a dielectric coating that reflected the UV but not visible light. A separate lamp was used during the alignment process, with the light passing through the optics to the microscope that the operator used to align the mask. [17]

[22] In early 1985, the first flatbed scanner for the IBM PC, the Datacopy Model 700, was released. Based on a CCD imaging element, the Model 700 was capable of scanning letter-sized documents at ...
This was an early example of how three-dimensional (ink) material printing (not called 3D printing in 1984) got started and now-a-days Additive Manufacturing (AM) does not reference historical jetting of hot-melt material properties used in 3D printing. 3D printing (printing with raised surface inks) was inkjet printing in the 1960–1980s with ...
