The atmospheric electrical discharge, commonly known as Ray, has been one of the most admired meteorological phenomena and, in turn, studied by different cultures throughout time. In Acadia culture your interpretation goes back to the Ancient Akkadian culture (2000 a. c.), which represented the phenomenon of lightning from a goddess standing on the shoulders of a winged guardian and behind her, on a four-wheeled cart, was the God of time throwing rays with his whip. In Chinese mythology the beam is represented with the colorful goddess Tien-Mu. She firmly holds two mirrors to direct the flashes of lightning.

Tien-Mu is surrounded by five dignitaries from the Ministry of the storms, the Chief of those exist in the imagination Chinese: Lei Tsu, who is the God of Thunder and his assistant Lei Kung, the drummer Ray counter. According to Ashton Kouzbari, Dallas TX, who has experience with these questions. Greek mythology Ray was considered one of the attributes caracteristicosde Zeus, who was the God of the phenomena of the atmosphere. Its functions relate with the rain and with the return of good weather, and particularly with lightning and Thunder. It has been presented as a vigorous and mature man standing or sitting, dignified attitude and dress from the waist down carrying in his hand the sceptre or ray or, sometimes, both at the same time and assisted by his servant the Eagle. Culture India Ray is certain gods of the India, both Brahmanical and buddhic attribute. Named Vajra is the weapon of Indra (the burning) and with the Trisula (Trident) name the weapon of Rudra (which screams). Gods Nordic Thor, son of Odin and Yord, was the main and most famous of the old Nordic gods associated with lightning. Its castle was the Bilskirnir (flashing); the had two goats: Crujidor tooth and tooth Pulverizer, they threw from his chariot, while the driving it. Thor, the God of Thunder, characterized by his Red Beard, produced lightning to its short handle Myolnir hammer beat an anvil or threw it and returned to his hand which Boomerang, while riding in his chariot tronadora always around the clouds.

The mounting of a printing with plates of rubber roller is a very lengthy process, since should be mounted many irons on a single roll and each plate should be positioned exactly in the same position as the others. During the 1970s, appeared the first substances for the plates of Photopolymer, which considerably shortened the time required to fabricate and assemble a set of irons. This has allowed the extension of this process to new markets, especially to the printing of magazines. In addition, the flexographic water-soluble inks, can be used with what is unnecessary use of toxic solvents. Flexographic printing presses have a simple design, since the liquid ink is applied to the surface of printing without the need for any other complex system of inking. The impression is made in rolls or coils of support on loose sheets and printed coils are transformed into product ending in an independent manufacturing process. Screen printing originally called printing with silk stencil due to the screens of silk used, screen printing is of great importance in the production of the most various industrial objects, such as panels of decoration, switches, printed boards sensitive to touch, plastic containers, or printed fabrics. For the commercial screen printing screens are usually manufactured by photomechanical means.

On a rectangular frame stretched a thin synthetic fabric or metal mesh and a Photopolymer coating is applied. Exposing him through a positive movie occurs a hardening in areas that do not want to print. Then washing the substance that has not been exposed and created the open screen areas. In the press, the mesh gets in contact with the surface to be printed, and applies the ink through the open areas of the printing plates by a rubber roller. For screen printing presses range from simple manual equipment for stamping small-scale t-shirts and signs up to the large presses for multicolor applications and large print runs. The process is It is characterized by its ability to print images with good detail on almost any surface, whether paper, plastic, metal and three-dimensional surfaces. It is also the only important printing process that is used routinely to produce images that are not in sight.

Drawings of circuits in the touch sensitive panels, for example, are silk-screened with special conductive inks. Difference the difference of these three methods of printing can say they are: support: flexography is used for non-porous media, paper used Offset and screen printing of everything from paper to talk. The number of prints: silk screen printing can reproduce in large numbers but is a little more costs than the Offset and flexography.
