Printing has undergone several changes through the years. Early methods of graphic communications has been found in pictographs, ideographs, and phonetic symbols. Printing has undergone several changes through the years. Early methods of graphic communications has been found in pictographs, ideographs, and phonetic symbols.

Pictographs are drawings that carry meaning because they look like the real object. An example of this are early cave paintings.

Ideographs arte drawings which symbolized an idea or concept rather than an object. Chinese writing is an example of this.

Phonetic symbols, which are what our modern day alphabet is derived from, are symbols that represent sound. When these symbols are combined properly, words are produced.

Scribes and Printing After the invention of the alphabet, books naturally were developed. Scribes were responsible for copying every word & every page in a book.

Gutenberg & a Wine Press In the mid 15th century moveable type was introduced. Johann Gutenberg created the very first printing press from an old wine press. This allowed for the mass book production to be done quickly. Scribes couldn’t copy the books fast enough.

Printing Today Printing technology has come a long way since then. When we refer to printing, we’re talking about a process of manufacturing multiple copies of graphic images.

5 major printing processes  Relief  Intaglio (Gravure)  Screen  Lithographic  Electrostatic  Relief  Intaglio (Gravure)  Screen  Lithographic  Electrostatic

Relief printing is producing an image from a raised surface. Intaglio images are transferred from a sunken surface. The industrial name for this is Gravure. Relief printing is producing an image from a raised surface. Intaglio images are transferred from a sunken surface. The industrial name for this is Gravure.

Screen printing transfers an image by allowing ink to pass through openings in a stencil that has been applied to a screen mesh. A lithographic image is produced from a flat surface. Screen printing transfers an image by allowing ink to pass through openings in a stencil that has been applied to a screen mesh. A lithographic image is produced from a flat surface.

Electrostatic printing involves creating an image by electrostatically charging areas of a special drum. As a result, the drum attracts a dry or liquid toner & the toner is fused to the paper.
