Drawing for Photo-Litho, and for Process Line-Blocks
The invention of photo-lithography enables the artist to make his own drawings or designs in black and white on a larger scale (usually one-third or one-half larger than required), which will be photo-litho’d down to the size required, thus preserving intact every touch and flexture of line in the original, and, by the reduction, gaining a fineness of line and beauty of finish which the artist could not himself produce on the reduced size. Machine Ruling may afterwards be transferred into the design when it is upon the stone, as in some of the designs in the accompanying examples.
“Process blocks,” which reproduce so admirably all kinds of drawings and engravings, are, when carefully printed, sometimes very difficult to detect from direct lithographs.
