Notes from the Past


Is the photo-mechanical process of producing line and half-tone blocks, used for what the philatelist calls the 'surface' or 'typographic' methods of print production (neither of which definitions are exact or descriptive of the means employed).  Briefly the process consists of photographing the artist's drawing, printing down on to sensitised zinc or copper, etching in acids leaving the printing surface in relief, and finally mounting the block type-high.  This master block can be duplicated the requisite number of times to produce the set required to print a whole sheet of stamps.
