Copperplate press
Many improvements have been introduced to Mr. F. Ullmer, a large manufacturer, for the annexed illustration of one of the most modern forms.
The Copperplate Press is employed in taking off prints or impressions from copper or steel plates, engraven, etched, or scraped, as in mezzo-tint. It is a description of rolling press, and consists of two rollers or cylinders supported on a strong frame. These rollers are moveable on their axes, one being placed just above the other. The table on which the plate to be printed is laid runs between the two. The upper cylinder is turned round by means of a cross fixed on its axis; the lower one is turned by the action of the upper on its surface. These rollers are so arranged as to admit of a greater or less amount of pressure.
