What kind of light is safe for screen printing?
Light Safe Yellow Bulbs are great in the dark room where you coat your screens with emulsion. They allow you to see what you’re doing without any risk of prematurely exposing your screens. Red bulbs can also be used, but we prefer the yellow bulbs because you can usually see a bit better with them.
Can you use any red light for darkroom?
Can I Use A Red Light To Develop Film? The only film you can use a red light when developing it is orthochromatic black & white film which is not sensitive to red light (red appears black in the images). However, most black & white film produced now is panchromatic and sensitive to red light, including a red safelight.
