diazo photo emulsion
Diazo photo emulsion represents a groundbreaking technology in the screen printing industry, serving as a light-sensitive coating that enables precise image transfer onto various printing surfaces. This innovative material consists of diazo compounds and polyvinyl alcohol, creating a unique photosensitive mixture that responds to ultraviolet light exposure. When applied to a screen mesh, the emulsion forms a thin, uniform layer that becomes water-insoluble when exposed to UV light, while unexposed areas remain water-soluble and can be washed away. This process creates a stencil that allows ink to pass through only in desired areas, producing detailed and accurate prints. The technology offers exceptional durability, with the ability to withstand multiple print runs while maintaining image clarity and edge definition. Diazo photo emulsion excels in both water-based and solvent-based printing applications, making it versatile across various industries including textile printing, electronics manufacturing, and artistic screenprinting. The material's chemical composition ensures optimal adhesion to mesh while providing excellent resolution for fine details and halftones, making it particularly valuable for complex designs and precise technical applications.
