McLantis manufactures world's first class pad printing emulsion, steel pad emulsion, steel plate emulsion
Pad printing photosensitive emulsion is a photosensitive material used to make pad printing steel plates. It is slightly yellow, transparent, and has a light odor. It has good acid and corrosion resistance and plays an important role in the etching process.
1. Steel Plate Selection: Choose the appropriate steel plate according to customer requirements, such as thick steel, thin steel, or resin plate.
2. Steel Plate Cleaning: Use a rag dipped in white spirit to clean the surface of the steel plate.
3. Photoresist Coating: Apply the photoresist manually or use a rotary coater, dip coater, or spray coater to evenly coat the surface of the pad printing plate with a layer of photoresist.
4. Drying: Place the coated pad printing plate in a drying oven for drying at a temperature of approximately 120-150°C for 10-15 minutes.
5. Plate Exposure: Attach the photoresist film to the appropriate location on the surface of the pad printing plate and place it in the plate exposure machine for exposure. At 500W power, the exposure time is approximately 30 seconds to 1 minute. (The exposure time varies depending on the plate exposure machine power and the size of the design.) 6. Development: Quickly apply developer water for about 10 seconds. Once a clear latent image appears on the plate surface, rinse with clean water to remove any impurities. Dry the plate at approximately 40-50°C.
7. Touch-up: Use adhesive tape to seal edges that do not require etching, and perform meticulous touch-up to ensure that no unnecessary sand holes appear in the printed area.
8. Etching: After touch-up, dry the plate again. Use a brush dipped in etching water to evenly scrub the latent image area for approximately 40 seconds, until clear image pits appear. (Etching time varies depending on the concentration of the etching water and the size of the design.)
9. Cleaning: Remove the adhesive tape, rinse the etching water, and wipe off any remaining photoresist with thinner. Measure the plate depth if necessary, maintaining it between 19-23 microns.
10. Storage: After developing, spray the steel plate surface with anti-rust oil to prevent rust.
