Screen printing is now the lifeblood of many mass printing businesses. It originally gained popularity in the 18th century, when silk mesh, a major component of screen printing, became more easily imported from the East. Screen printing became popular in the advertising sector in the nineteenth century, and it has since been utilised widely across various industries, including retail and electronics, due to the simple personalisation screen printing on plastic options it provides.
While screen printing may be done manually, especially for short print runs, it is most typically done automatically, employing modern inks and screen printing on plastic materials in conjunction with computer technology to mass print. One of the most significant benefits of screen printing is that it can print on practically any surface, including fabric, paper, glass, wood, card, plastic, and leather. This article will go through the screen printing method, its applications, kinds, and advantages.
How Does It Function?
Screen printing can be done by hand or by machine, but the fundamental method remains the same. The type of ink utilised, the produced effect, and the printed surface can all change. The screen printing on plastic procedure is detailed below:
CREATE A DESIGN
The first stage in the screen printing procedure is to create the design. After deciding on a design, it is printed onto a transparent acetate film, which is then used to make the screen or stencil.
CHOOSE AND PREPARATION OF THE SCREEN
When the design is complete, it is time to choose the screen printing on plastic and mesh count. The total number of fibres in one square inch is referred to as the mesh count. The mesh count required will be determined by the design being printed: A larger mesh count helps print finer details while yet retaining a good ink coating.
CREATE A STENCIL
Exposing the screen for a set amount of time hardens the exposed parts of the screen, and any residual unhardened emulsion is washed away, leaving a distinct impression on the screen. The screen is then dried, and any necessary touch-ups are performed by the printer to ensure that the imprint is as near to the original design as possible.
The material to be printed is laid flat on the printing board, and the screen is positioned on top of it in the proper location, ready to be printed.
APPLYING THE DESIGN TO THE SCREEN PRINTING
The printed design will come to life at this stage. The screen printing on plastic is being lowered to the printing board. The required colour ink is put on the screen’s top. A squeegee will disseminate ink uniformly down the length of the screen. The ink presses through the stencil’s exposed sections and transfers to the underlying silk, printing the design on the goods.
FINISHING & HEAT CURING
Finally, the printed object is heat-cured by being passed through a drier, resulting in a smooth pattern. This is done to prevent the screen printing on plastic design from fading.
