positive screen printing
Positive screen printing is a versatile and widely-used printing technique that revolutionizes how images and designs are transferred onto various surfaces. This method involves creating a stencil, known as a screen, where the design areas are open while non-printing areas are blocked out. The process begins with a positive image being created on a transparent film, which is then used to expose a photosensitive emulsion applied to the screen mesh. When UV light hits the screen, it hardens the emulsion in non-image areas, while the areas protected by the positive image remain soft and can be washed away, creating the stencil. During printing, ink is pushed through these open areas onto the substrate beneath using a squeegee. This technique offers exceptional versatility in terms of substrate compatibility, allowing printing on materials ranging from textiles and paper to glass and metals. The technology enables precise ink deposit control, making it ideal for both fine detail work and heavy coverage applications. Modern positive screen printing has evolved to incorporate advanced automation systems, precise registration controls, and sophisticated ink formulations, making it an indispensable process in industries from textile manufacturing to electronics production.
