Silkscreen printing is the great technique of the printing. in this kind of printing you can print anything easily like textile, wood, plastic, marble, iron, steel, school bags, prize shields, special deed, books covers, hates, pen caps, glass, mirror, horde rubber and also you want. There are many more things which can to print with screen printing. These are simple thing for screen printing, but some equipment is to do print for special purpose as a marble etching and metal etching. Before the etching to must does a print with screen on the marble, metal and which you want to do etching. Etching is the procedure of using physically powerful acid or caustic to slash into the defenseless areas of a metal exterior to make a required design in intaglio in the metal (the basic method—in current developers further chemicals may be used on further forms of stuff). While an intaglio technique of printmaking it is correctly for sufficient results of etching, besides engraving, this is the very significant technique for old printer masters and remains extensively used today as you want to do.
In the proper etching, a metal (typically copper, zinc, iron, metal, ceramics or steel) plates are covered with a waxy opinion which is anti to acid. The artist when grazes off the ground with a sharp etching spine where he needs a line to show in the ended piece, thus exposing the nude metal. The échoppe, an instrument with a distorted elliptical section, is also used for “bulge” lines. The plate or further stuff is then dipped in a tub of acid, this work is officially called the mordant (French for “biting”) or etchant, or has acid washed above it. The strong acid “bites” into the metal or marble, where it is showing, leaving at the back lines ruined into the etching plate. The remaining position is then cleaned off the metal or marble plate. The plate is covered with ink, and afterward the ink washed off the plate surface, leaving just the ink in the etched areas.
After that the plate is then situated by an insistent pressure, printing press jointly with a sheet of paper (habitually moistened to diminish it). In this work the paper picks up the ink from the etched appearance, making a print. This method can be repeated more times; usually some hundred imitations (copies) could be printed before the plate confirms much sign of wear.
