label: Description (Brief)
content: Security printing demanded that all prints be identical, but there were difficulties in achieving that goal by the preferred intaglio process. Dampened paper changed its dimension and was further distorted by the rolling press; while dry paper would not take an impression at a rolling press without immense pressure, which stretched the plate and image. Printing in several colors (a protection against photographic reproduction) compounded the distortions, making perfect registration between the colors impossible. This patent sought to avoid the problems by means of an intaglio press built along the lines of a coining press. It printed on dry paper, using a combination of screw and lever pressure.
