Offset printing comes from the oldest method of lithography, in 1976 the German Aloys Senefelder experimenting with a method that allows you to print with a planographic, that is without parts in recess or in relief.
The system, formerly known as “chemical printing on stone” (lithography) uses a special type of stone obtained from quarries Solenhofen, Monaco of Bavaria, with hydrophilic ie water retention, so to exploit the repulsion between water and fat (inks), the stone is first drawn with a pencil, lipophilic areas (graphic elements inked), while the remaining surface retains a thin veil of water.
