Printing is a branch of production, bringing together the different ways the printed reproduction of text production, illustration, etc., in the form of newspapers, magazines, books, booklets, posters, labels, maps, forms and many other varieties of printed products. Printing Technology helps with the technical facilities to receive a specified number of identical copies of graphic images – letters, signs, drawings. The basis of the principle of printing reproduction, or transmission, in other words, the printing of the material, which is called the plate on a surface – printed material. There different ways to transfer images from the printing plate to the substrate. First – this is high (or typographic) method in which the printing elements are located above the non. When applied to printed form, it only covers the printing form, and thus only these elements will print on the printed material. The second way – intaglio printing, which is a mirror image of letterpress printing, which the printing area in the recess, and elevated white space. The third way – a flat printing, where print and non-printing areas are in the same plane.
In technology, conceived the idea of a flat print print first on a cylinder with an elastic (rubber) coating, and only after the image is transferred from the cylinder to the paper. Thus, the portable has been enhanced or offset printing, which reached a high time level. At present it is considered a universal technique of printing, offset printing is gradually displacing even from areas that are once her main area printing processes – processes of transfer of ink from printed form (sometimes using an intermediate medium such as a blanket cylinder) to the substrate, as well as related preparatory operations Printing – this is repeated to obtain the same images with the specified quality parameters by transferring ink from the printing plate (either directly or through an intermediate surface) na substrates.
