screen printing squeegee blades supplies

Screen printing squeegee blades are an essential component in the screen printing process. They are responsible for pushing the ink through the mesh of the screen and onto the printing substrate. Without a proper squeegee blade, the ink will not be distributed evenly, resulting in a poor quality print.

Squeegee blades come in various shapes and sizes, and they can be made of different materials, such as rubber, urethane, or silicone. The choice of the blade will depend on the type of ink being used, the substrate being printed on, and the desired outcome of the print.

Rubber squeegee blades are the most commonly used blades in screen printing. They are affordable and can be easily replaced when they wear out. Rubber blades come in different durometers, which is the measure of its hardness. A softer blade is better suited for printing on delicate fabrics, while a harder blade is better for printing on thicker substrates like plastic or glass.

Urethane squeegee blades are a bit more expensive than rubber blades, but they last longer and can be used for printing on a wider range of substrates. They have a more uniform surface, which helps to distribute the ink evenly, resulting in a higher quality print. Urethane blades also come in different durometers, giving screen printers more flexibility in their printing process.

Silicone squeegee blades are the most expensive of the three, but they are the most durable and long-lasting. They are ideal for printing on substrates that require a high level of precision and consistency, such as electronics or medical devices. Silicone blades are also the easiest to clean and maintain, making them a popular choice for high-volume printing.

When selecting a squeegee blade, it is essential to consider the size and shape of the blade. The blade should be slightly larger than the printing image to ensure that the ink is distributed evenly across the entire image. The shape of the blade can also affect the quality of the print, with some shapes being better suited for printing on certain substrates.

In conclusion, screen printing squeegee blades are a crucial component in the screen printing process. The choice of blade will depend on the ink being used, the substrate being printed on, and the desired outcome of the print. Rubber blades are the most commonly used, while urethane and silicone blades are more durable and offer more flexibility in the printing process. When selecting a blade, it is important to consider the size and shape of the blade to ensure a high-quality print.
