Major Types Screen Printing


The main merits of screen is done independently of the rest of the printing process other methods, they can print on surfaces of any shape, size. Another important benefit included silkscreen is thicker than the ink can be used as other printing techniques. This feature facilitates some very interesting topics that are not feasible in other forms of printing process. The process of applying this technique is as simple as allowing a wider use of inks and colors for use in screen printing of the press, the use of other options.

With the use of screen printing, production records have been enhanced which also means that the screen printing is a process faster, and it is more flexible. This is the result of the evolution of the rotation of the printing machine, one of the best inventions and dryers UV inks hardening. The chemicals are used in the process of screen printing screen, emulsions, paints and solvents, surfactants, alkalis and oxidants screen uses regeneration.

Types of screen printing presses

Screen printing machines are three main types, namely:
• The flat-bed
• Cylinders
• Rotary

Flat bed and cylinder presses

Gear is one of the most widespread species on screen. The flat-bed press and the cylinder have the same properties, they use both a flat panel, as well as three stages of piston compressors for the implementation of the operating pressure. The screen is moved on the merits, then scraping tool is pressed into the mesh and image and, finally, the screen is removed from the substrate and allows for a completion of the process. With the help of the flat-bed press to print the thing lies on a bed horizontal print simultaneously on the screen. In the case of the bottle, press the thing is to be printed on the cylinder.

Rotary presses screen

These machines are being developed to ensure continuous monitoring, High-Speed Web pressure. The screens of these presses are very thin metal cylinder. The cylinders are open and they fall on both ends, and they cover blocks on the front page of the press. During the printing ink is pumped through one end of the cylinder, so he continuing flow of ink. The raclette is a continuous process bar floating freely inside the cylinder. The pressure of raclette is maintained by the magnet bars, push it under the bed. It is most often used for printing textiles, wallpaper and other substances, an unbroken continuity model.
