So let me explain the type of screen printing I’ll be showing you. It is screen printing with a photo emulsion. In general terms, you paint a screen with light sensitive paint, let it cure, put your image on top of the paint when it’s dried and cure it under lights. The area of the screen that is covered up by your image will not get cured because it won’t be exposed to light. Therefore after your screen is “exposed”, all the area under your image will just wash away under water. This clean area in the shape of your image or text … is your screen printing pattern, where you will drag ink across to create your screen printed tee shirt, bag, or tea towel.
