Its versatility is the great strength of screen printing. This printing technology can print well on almost any material. The reliable, high opacity is particularly in the spotlight.
From stencil art to screen printing
Walls or playing cards have been printed with the help of simple templates in Europe since the Middle Ages. In Japan and China there were ancestors of screen printing, high-quality textiles were finished with. At the beginning of the 20th century, the multicoloured screen printing came from the U.S. to Europe. At first, advertising signs and posters as well as printing of textiles are the major fields of application.
It depends on the screen fabric
Basis of screen printing is a screen made of special fabric the ink is squeezed through. Therefore, screen printing is also known as porous printing. What is not to be printed is covered on the screen - the principle of the template. An important parameter is the fineness of the screen: the finer the mesh, the more accurate the reproduction of lines.
If the fabric is coarse-mesh, the ink application will be stronger.
Strong arguments in the reproduction
Strong arguments plead for screen printing in the decoration of tubes or cans: Due to the strong colour opacity the filling good does not shine through. The reproduction of planes and lines succeeds best, as well as the reproduction of white areas on a dark background. Even under strong light screen colours remain unchanged.
The printing process with seven advantages
- screen printing inks have excellent covering properties
- thus the filling does not shine though
- no modification of the colour due to light irradiation
- optimal for surfaces and lines
- clear contrast for bar code readers
- permits varying ink layer thicknesses for tactile effects (e. g. braille)
- optimal reproduction of white colours
