What kind of originals and methods are suitable for screen printing mesh?
Screen printing mesh suitable originals: Screen printing, like other printing, requires accurate reproduction of the text and color of the original. The original used in screen printing is in principle not very different from the original used in other printing methods, but in specific plate making and printing practice, the requirements are different, which is mainly determined by the characteristics of screen printing. In particular, since the screen printing ink layer is thick and bright, it is necessary to fully consider the special effects of screen printing when selecting the original and plate making.
In addition, the accuracy of the lines and dot requirements of the original used in screen printing is also different from that required for the ordinary printing method. If the lines and dots of the original are very fine, it is very difficult to use screen printing. Therefore, the screen printing technique is not suitable for reproducing originals of fine lines and dots. In the selection of the printing method, it is necessary to fully consider the characteristics of various printing. Even in the screen printing plate making, it is also necessary to pay attention to selecting a suitable network cable in order to achieve the purpose of sufficiently reproducing the original.
Screen printing is more suitable for a monochrome set of color originals with bright text and lines. It is also suitable for color originals with large contrast and clear levels. Through the special effects of screen printing, the replica has rich expressive power, and fully expresses the texture and stereoscopic effect of the original content by enriching the contrast between the thick ink layer and the hue.
Screen-printed photo-imprinted originals are available in both reflective and transmissive originals, usually using a reflective original. Most of the color photography uses a transmissive original.
Screen printing mainly uses a positive picture to make a screen. Different plate making methods have different requirements for originals.
There are usually two types of screen printing, manual printing and mechanical printing.
Manual printing refers to the movement from the continuous feeding to the delivery, the upper and lower movement of the printing plate, and the scraping and squeegeing are all manual operations.
Mechanical printing means that the printing process is done by mechanical action. It is divided into semi-automatic and fully automatic printing. Semi-automatic means that the substrate is placed and removed by manual operation, and printing is done by mechanical; fully automatic means that the entire printing process is completed by machinery.
