anastásico 18
ANASTATIC Embossed engraving process, usually on zinc plates, used in the nineteenth century to reproduce previously printed material, including drawings and type pages. The new matrix is obtained by transporting it by photograph from the typographic page to the stone: anastatic reproduction. Another more technical method of the procedure is to moisten a printed page with hypophosphoric acid, which has the virtue of raising the ink. Then the page is placed on a zinc plate, and subjecting it to a strong pressure, the zinc will take part of the ink. Then a roll can be made the same as by the lithographic procedure.
