In screen printing, which thick liquid forms the stencil by blocking areas of the screen?

• A. Gelatin
• B. Ink
• C. Emulsion
• D. Paint

Answer: (C)

The stencil in screen printing is built from a thick, light-sensitive liquid called emulsion. You coat the screen with emulsion and let it dry, then expose it to light with your design. The exposed areas harden and become a durable barrier, while the unexposed areas are washed away. That hardened emulsion blocks ink from passing in the places you don’t want printed, creating the stencil. When you push ink across the screen, it only goes through the open, unblocked areas to reproduce the image. Gelatin isn’t the standard material for making the stencil on modern screens, and ink or paint are what you push through the screen rather than form the stencil itself.
