Graphics (from Greek ; see -graphy) are visual presentations on some surface, such as a wall, canvas, computer screen, paper, or stone to brand, inform, illustrate, or entertain. Examples are photographs, drawings, Line Art, graphs, diagrams, typography, numbers, symbols, geometric designs, maps, engineering drawings, or other images. Graphics often combine text, illustration, and color. Graphic design may consist of the deliberate selection, creation, or arrangement of typography alone, as in a brochure, flier, poster, web site, or book without any other element. Clarity or effective communication may be the objective, association with other cultural elements may be sought, or merely, the creation of a distinctive style.

Graphics can be functional or artistic. The latter can be a recorded version, such as a photograph, or an interpretation by a scientist to highlight essential features, or an artist, in which case the distinction with imaginary graphics may become blurred.

History

main: History of graphic design The earliest graphics known to anthropologists studying prehistoric periods are cave paintings and markings on boulders, bone, ivory, and antlers, which were created during the Upper Palaeolithic period from 40,000–10,000 B.C. or earlier. Many of these were found to record astronomical, seasonal, and chronological details. Some of the earliest graphics and drawings known to the modern world, from almost 6,000 years ago, are that of engraved stone tablets and ceramic cylinder seals, marking the beginning of the historic periods and the keeping of records for accounting and inventory purposes. Records from Egypt predate these and papyrus was used by the Egyptians as a material on which to plan the building of pyramids; they also used slabs of limestone and wood. From 600–250 BC, the Greeks played a major role in geometry. They used graphics to represent their mathematical theories such as the Circle Theorem and the Pythagorean theorem.

In art, "graphics" is often used to distinguish work in a monotone and made up of lines, as opposed to painting.

Drawing

main: Technical drawing

Drawing is generally considered distinct from painting, in which colored pigments are suspended in a liquid medium and are usually applied with a brush. Notable great drawers include Michelangelo, Rembrandt, Raphael and Leonardo da Vinci.

Many people choose drawing as a main art style, or they may use it to make sketches for paintings, sculptures and other types of art.

Printmaking

main: Printmaking Woodblock printing, including images is first seen in China after paper was invented (about A.D. 105). In the West the main techniques have been woodcut, engraving and etching, but there are many others.

Etching

main: Etching

Etching is an intaglio method of printmaking in which the image is incised into the surface of a metal plate using an acid. The acid eats the metal, leaving behind roughened areas, or, if the surface exposed to the acid is very thin, burning a line into the plate. The use of the process in printmaking is believed to have been invented by Daniel Hopfer (circa 1470–1536) of Augsburg, Germany, who decorated armour in this way.
