Off set print
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.
