The traditional definition of printing are: the original manuscripts or images based on the use, directly or indirectly into plates, and then on the plate before putting the adhesion of pigment, in the role of mechanical stress, so a certain amount on a plate the adhesion of pigment transfer to the substrate surface, which are copied into a batch of product technology.
Print is divided into two categories: direct printing, and indirect printing. Conventional printing, you must have to have the manuscript, printing plates, printing materials, printing inks, printing machinery, the five elements.
Printing process is divided into the original selection, pre-press design and graphic information processing, plate making, printing, finishing. To make into a perfect print, every step is very important.

In the history of mankind, printing was one of the greatest inventions. The invention of the printing press, development and dissemination of human civilization and world progress up huge role. Below I introduce printing.
Printing of the traditional definition is: to the text manuscript or image manuscript as the basis, using direct or indirect way to plate, plate made again in the apply the adhesion of pigment in mechanical pressure, under the action of plate on the amount that adhesion pigment transferred to print surfaces, thus obtains copied into the product batch of technology.
Printing was divided into two types: direct and indirect printing, printing. Conventional printing, must possess the manuscript, printing, printing, printing inks, things printing machinery, five factors.
Printing process is divided into the original manuscript of the choice, pre-press design and graphic information processing, plate-making, printing, postpress. Want to make a perfect prints, every step is very important.
