2. Traditional Techniques
One traditional technique is etching. Etching is where printing
produced by the process of etching. Etching is traditionally the process
of using strong acid or mordant to cut into the unprotected parts of
a metal surface to create a design in intaglio in the metal.
Letterpress printing is a technique of relief printing using a printing
press, a process by which many copies are produced by repeated direct
impression of an inked, raised surface against sheets or a continuous
roll of paper.
3. Lithography
The term Lithography means the process of printing from a flat surface treated so
as to repel the ink except where it is required for printing. It was invented in 1796
by German author and actor Alois Senefelder as a cheap method of publishing
theatrical works.
Today, most types of high-volume books and magazines, especially when illustrated
in colour, are printed with offset lithography, which has become the most common
form of printing technology since the 1960s.
4. Printing
Printing is a process for reproducing text and images using a master
form or template. His printing press played a key role in the
development of the Renaissance, Reformation, the Age of
Enlightenment, and the scientific revolution and laid the material basis
for the modern knowledge-based economy and the spread of learning
to the masses.
