Screen printing is a popular technique for transferring designs onto fabrics and other materials. However, the process requires a darkroom for preparing and exposing screens, which can be a challenge for those unfamiliar with the process.
One important component of a screen printing dark room is the lighting. In order to expose the emulsion on the screen, the room must be completely dark except for a special light source called a dark room light. These lights emit a specific spectrum of light that does not affect the emulsion, allowing the design to be accurately transferred onto the material.
There are a few different types of dark room lights to choose from, including LED lights, fluorescent lights, and incandescent lights. LED lights are popular due to their energy efficiency and long lifespan. They also emit little heat, which can be beneficial in a small and enclosed space.
Fluorescent lights are another option and are commonly used in commercial screen printing shops. They are relatively inexpensive and emit a bright, even light. However, they produce some heat, which can be a concern in a smaller dark room.
Finally, incandescent lights are the traditional choice for dark room lighting. They emit a warm, yellow light that is easy on the eyes and provides good color rendering. However, they are less energy efficient than LED and fluorescent lights and do produce heat.
No matter which type of dark room light you choose, it's important to ensure that the light is properly shielded to prevent any stray light from entering the room. This can be achieved through the use of blackout curtains or by painting the walls and ceiling with light-blocking paint.
The lighting in a screen printing dark room is a crucial component in the screen printing process. By selecting the right type of light and properly shielding the room from any stray light, you can ensure accurate and high-quality results in your screen printing projects.
