How Does Screen Printing Work?

Screen printing is a method of printing on a variety of materials. The process involves applying ink to a screen made of a polyester mesh, which forms the stencil. Each layer of ink is applied to a different screen. When it dries, the screen is washed and is ready for use again. Once the design has been completed, the screen is ready for the next step in the printing process. The following steps will explain how to screen printing works.

First, the printer must choose the appropriate type of mesh screen to match the design. Next, he or she applies a layer of emulsion on the screen. This emulsion hardens when exposed to a strong light, so a bright light must be used to dry the emulsion properly. The acetate sheet is then placed onto the emulsion-coated mesh. Finally, the screen is exposed to a bright light. The emulsion will remain liquid on the screen covered with the design.

Screen printing’s popularity in the United States grew quickly during the New Deal era, when the WPA helped produce thousands of silk-screened posters to encourage Americans to visit different regions of the country. These posters promoted various federal programs, public health messages, and theater and musical performances. The first promotional t-shirt, featuring the famous text font, was produced for the movie “The Wizard of Oz” in 1939. The technology grew during the Second World War and remained a popular form of print long after the war was over.

The first patented screen printing method was made in the early 20th century by Samuel Simon. The process involved a fabric called a screen made of a silk screen. This fabric was chosen because it would guarantee greater tensile strength and size stability. Simon used rubber blades to push the ink through the screen, which is still used today. Initially, Simon’s method was used to create custom wallpaper for the wealthy. Later, it was refined with the inclusion of photo-reactive chemicals and gelatin.

Screen printing is most common for high volume printing and repeated batches of printed material. As the quantity of orders increases, screen printing becomes increasingly cost-effective. Screen-printed products can be reused, allowing repeat-runs of the same design. Although the production process takes longer, the quality and price of screen-printed goods are well worth the investment. It is important to note, however, that screen-printed items may not be suitable for all purposes.

Another advantage of screen-printed products is that they can be personalized. Since screen-printed items are curved or uneven, they can be printed with unique designs. Screen printing is also best suited for super-high-quantity print runs. However, screen printing requires a large set-up per print and only prints one color at a time. Screen-printed products can suffer from color bleeding and alignment problems. For this reason, it is not the best option for multi-colored designs.
