Engraved images are created with three simple steps. First the image is acid-etched, hand-tooled or photoengraved into a copper (shown above) or steel plate. Next, the recessed image is filled with a very opaque, environmentally friendly ink. Then, with pressure of up to two tons per square inch, the paper is forced into the ink filled portion of the plate. The result is a finely detailed image embossed on the surface of the paper, with a subtle impression mark on the back of the sheet. The benefits achieved via engraving are many, but the process is as simple as I, II, III.
