lithograph meaning

The term Lithography in its literal meaning is to write in stone according to the Greek. Lithography was invented in 1798 by Alois Senefelder and to this day it has become a widespread and widely used printing process for both artists and printing companies using this system. The lithographic printing process makes use of the impossibility of mixing between fat and water.

lithography general process

In lithographic printing process it consists in that the ink is applied to an image treated with grease on the flat printing surface. Non-image or colorless areas that retain moisture repel lithographic ink. This inked surface is printed, either directly on paper or through a special press such as a rubber cylinder as is the case with commercial printing.

Offset lithography

Going more into the detail of the current process, offset lithography, depends on photographic developments, malleable aluminum, polyester, mylar or paper plates are used instead of stone tablets. Modern lithography plates have a crushed texture and are covered with a photosensitive emulsion. A photographic negative of the desired image is placed in contact with the emulsion and the plate is exposed to ultraviolet light. After its elaboration, the emulsion shows a reverse of the negative image, which is a duplicate of the original image that would be the positive one. The image on the plate emulsion can also be created by direct laser imaging on a platesetter device. The positive image is the emulsion that remains after the image. The non-image portions of the emulsion have traditionally been removed by means of a chemical process, although in the last period plates have arrived that do not require such processing.

Lithography Examples

Modern lithography in its handling of high volume is used to produce posters, maps, books, newspapers and packaging, in general it could be said that a smooth printing with a large order of volume and graphic details is made by means of lithographic printing. Most books are currently made by means of offset lithography.
