The Projectina universal comparison projector was used to compare and examine surface detail on typewritten documents, high-speed computer printouts, photocopies, fracture matches, and mechanically produced documents. The observations made by using the side-by-side prism or the superimposition mode optical block were photographically recorded. The Projectina magnifies and projects two items so that similarities or differences can be determined.
