Table Exposure Unit

A common type of screen-printing exposure unit, the table unit is portable and affordable. This unit requires minimal space to use and features a clear acrylic lid that lets you easily insert the screen and emulsion. It also uses a metal frame that is covered with a black neoflex rubber-flex blanket, which resists tearing and pinholes. The blanket ensures that the light only hits where it is needed, exposing the screen with high definition and precision.

Conventional White Light Exposure Unit

Conventional white light exposure units are a popular option for new screen printing businesses because they are inexpensive and easy to use. However, they may not produce the same quality of exposure as other units. Additionally, conventional white light exposure units typically require longer exposure times, which can slow down the screen-printing process.

Compression Exposure Unit

A compression exposure unit is an effective and affordable option for new screen printing businesses that plan to print spot color prints, like block text or line art. The unit uses a weighted cover that compresses the screen, film, and emulsion to create contact between them. This pressure will create an even burn in the emulsion that is exposed to the light, which will then be burned into the screen.

UV LED Exposure Unit

UV LED exposure units are becoming increasingly popular for screen-printing shops because they offer fast exposure times, accurate results, and a long lifespan. They also have a low heat output and are energy-efficient. They are ideal for any size shop, as they can accommodate any number of screens and can fit on a table or in a cabinet.

Using an exposure calculator is the best way to determine how long you should leave your screen in the exposure unit for it to fully develop. Once you know how long to expose your screen, it's important to follow the manufacturer's instructions regarding the emulsion you are using to ensure optimal results.
