Industrial screen printing is a printing technique that uses a mesh screen to transfer ink onto a substrate, such as paper, fabric, or metal. The screen is made of a fine mesh, and the areas of the screen that are not covered by the design are blocked off with a light-sensitive emulsion. When the screen is exposed to light, the emulsion hardens and becomes impermeable to ink. The ink is then applied to the screen, and a squeegee is used to force the ink through the open areas of the screen and onto the substrate.
Industrial screen printing is a versatile printing technique that can be used to create a wide variety of products, including t-shirts, posters, banners, and signs. It is a relatively inexpensive printing method, and it can produce high-quality prints with sharp colors and fine details. Industrial screen printing is also a durable printing method, and the prints can withstand exposure to the elements and wear and tear.
The process of industrial screen printing involves several steps:
- The first step is to create a design for the print. The design can be created using a computer graphics program or by hand.
- Once the design is created, it is transferred to a screen. The screen is made of a fine mesh, and the areas of the screen that are not covered by the design are blocked off with a light-sensitive emulsion.
- The screen is then exposed to light, which hardens the emulsion and makes it impermeable to ink.
- The ink is then applied to the screen, and a squeegee is used to force the ink through the open areas of the screen and onto the substrate.
- The print is then dried, and the process is repeated for each color in the design.

1. Mesh Size
Mesh size is an important factor to consider when using an industrial screen printer. The mesh size will determine the fineness of the print, with a higher mesh count producing a finer print and a lower mesh count producing a coarser print. This is because the mesh size determines the amount of ink that can pass through the screen. A higher mesh count will allow less ink to pass through, resulting in a finer print. Conversely, a lower mesh count will allow more ink to pass through, resulting in a coarser print.
The mesh size that is used will depend on the specific application. For example, a high mesh count would be used for printing detailed designs on fabric, while a lower mesh count would be used for printing bolder designs on cardboard.
It is important to choose the correct mesh size for the job in order to achieve the desired results. If the mesh size is too high, the print may be too faint. If the mesh size is too low, the print may be too coarse.
By understanding the relationship between mesh size and print quality, you can use an industrial screen printer to create high-quality prints that meet your specific needs.
2. Emulsion Type
The type of emulsion used on the screen is an important factor to consider when using an industrial screen printer. The emulsion will determine the durability and light sensitivity of the screen, which in turn will affect the quality of the printed image.
There are two main types of emulsions used in screen printing: diazo and photopolymer. Diazo emulsions are less durable but more light sensitive than photopolymer emulsions. This makes them ideal for printing on fabrics, which are delicate and can be damaged by high levels of light exposure. Photopolymer emulsions are more durable but less light sensitive than diazo emulsions. This makes them ideal for printing on substrates that are not as delicate, such as paper or metal.
The type of emulsion that you choose will depend on the specific application. If you are printing on a delicate substrate, such as fabric, you will need to use a diazo emulsion. If you are printing on a more durable substrate, such as paper or metal, you can use a photopolymer emulsion.
Understanding the different types of emulsions and their properties is essential for using an industrial screen printer effectively. By choosing the correct emulsion for the job, you can ensure that you produce high-quality prints that meet your specific needs.
3. Squeegee Pressure
Squeegee pressure is an important factor to consider when using an industrial screen printer. The pressure applied by the squeegee will determine the amount of ink that is transferred to the substrate, which in turn will affect the quality of the printed image.
If too much pressure is applied, the ink may bleed or spread beyond the desired area. This can result in a messy and unprofessional-looking print. Conversely, if too little pressure is applied, the ink may not transfer to the substrate properly, resulting in a faint or incomplete print.
The correct amount of squeegee pressure will vary depending on the type of ink, the substrate being printed on, and the desired print quality. It is important to experiment with different pressure levels to find the optimal setting for the specific application.
Understanding the importance of squeegee pressure is essential for using an industrial screen printer effectively. By carefully controlling the pressure applied by the squeegee, printers can produce high-quality prints that meet their specific needs.
