What is Screen Printing?

The History of Screen Printing

Screen printing emerged from the old technique of stencilling in the late 1800s, and the method has expanded into an industry with adjustments over time.
It was still a rudimentary procedure in the nineteenth century, with fabrics like organdy spread across wooden frames to hold stencils in place while printing. The method was only mechanised in the twentieth century, and it was mostly used to print flat posters, packaging, and fabrics.

Screen printing spanned the gap between hand fed production and automated printing, which was significantly more expensive, at first, despite the fact that it was not a well-known process. It swiftly moved from handicraft to mass manufacturing, especially in the United States, and opened up a whole new realm of print capabilities while also transforming the advertising sector.

It has evolved into a highly complicated process that incorporates innovative materials and inks as well as computer technologies. Screen printing is frequently used to replace other processes such as offset litho. It can print a picture on virtually any surface, including paper, card, wood, glass, plastic, leather, and almost any fabric. The iPhone, solar cells, and hydrogen fuel cells are all screen printed products that would not exist if it weren’t for the printing process.

Production

Screen printing is a method of obtaining a desired picture by employing a woven mesh screen to support an ink-blocking stencil.

By pressing ink or other printable materials through the mesh as a sharp-edged picture onto a substrate, the screen stencil creates open sections of mesh that transfer ink or other printable materials (the item that will receive the image).

During the squeegee stroke, a squeegee is moved across the screen stencil, forcing ink through the mesh apertures to wet the substrate. The ink remains on the screen as it rebounds away from the substrate. It is the method of applying ink to a substrate, such as t-shirts, posters, stickers, vinyl, wood, or other materials, using a mesh-based stencil.

Screen printing is also sometimes known as silkscreen printing. One colour is printed at a time, so several screens can be used to produce a multicoloured image or design

When and when does screen printing come into play?

Screen printing is most usually linked with T-shirts, lanyards, balloons, bags, and products, but it’s also used to apply latex to promotional printed scratch cards and for a decorative print method known as spot UV.
The clear coating is subsequently subjected to UV radiation lamps for drying, using the same squeegees and screens as before.
Spot UV is a terrific technique to take your print to the next level. It’s typically used to enhance logos or show certain words.
