Drawing printing method, involves creating key drawing on granulated glass plate surface by graphite pencil, chalk, ink or paint to obtain lithographic grain and laying surface on offset aluminum plate to reproduce drawing on aluminum plate

摘要

The method involves granulating a surface of a transparent glass plate with sand or aluminum oxide. A key drawing is created on the granulated surface of the glass plate using a graphite pencil, chalk, ink or paint to obtain a lithographic grain. The plate surface is then laid on an offset aluminum plate to reproduce the drawing on the offset aluminum plate for printing the drawing using lithographic, etching and offset press.
