What is Screen Printing Exposure?

Screen printing exposure is a crucial step in the screen printing process that involves transferring an image onto a screen for printing. This process begins with a design being printed onto a transparent material, such as a film positive. The design is then placed on a screen that has been coated with a layer of photosensitive emulsion. The screen is then exposed to a strong light source. The light hardens the emulsion on the areas of the screen not covered by the design, while the emulsion under the design remains soft and can be washed away, leaving a stencil of the design on the screen. This stencil can then be used to apply ink onto the printing surface, replicating the original design. The quality of the exposure can greatly affect the final print, making it a critical step in the screen printing process.
