As detailed by ScreenPrinting-ASPA in their article “Exposing a Screen,” the process of exposing or “burning” a screen is fundamental to the screen printing process. This critical step involves using a light source to transfer artwork onto a screen coated with photo emulsion.
Emphasizing the importance of using high UV light sources for the best results, the process begins with printing artwork onto a film positive, which is then placed on the exposure unit glass. The light exposure hardens the emulsion except where the artwork blocks it, creating a stencil. This stencil is washed out with water, leaving open areas for ink to pass through during printing.
Their approach includes using a homemade exposure unit with fluorescent bulbs, ensuring proper warm-up time for optimal light output. Cleanliness of the exposure unit glass is also stressed to avoid imperfections on the screen.
Dedication to precision in screen exposure is part of a broader commitment to delivering high-quality screen printing solutions. Expertise in this essential process ensures that customers achieve perfect stencils and vibrant prints every time.
