The production method of transfer printing steel plate
1. Steel plate cleaning (washing), removing oil stains and dust on the steel plate, must be thoroughly cleaned, without any stains or dust;
2. Apply photosensitive adhesive evenly on the surface of the steel plate, and use a slurry thrower to spin the slurry. Then tilt it back and place it in a dark box (reverse tilt: photosensitive adhesive facing downwards). If there is no slurry thrower, after sizing, it will be directly tilted back and placed in a dark box. The darkroom should be cleaned to avoid dust. Drying of photosensitive adhesive requires 12 hours at room temperature, using an industrial oven to bake at 150 degrees Celsius for 15 minutes. It is generally not recommended to bake, and it is best to use room temperature;
3. Stick the film on the appropriate position of the steel plate and fix it with transparent tape;

4. Plate drying, the glass of the plate drying machine is clean and dust-free, and the photosensitive adhesive surface is tightly attached to the plate drying machine glass. (The operation of the plate drying machine is omitted) Exposure parameters: generally, the exposure time is 40 seconds, and the dot exposure time is 8-10 seconds;

5. To develop, rinse with developer solution for 20-40 seconds, then rinse with clean water. If insufficient development is found, repeat the developer solution rinse and water rinse until the image and text are completely presented, and then dry with a hair dryer;

6. After drying the water, stick it with adhesive tape on the areas that do not need to be etched, and then fill the sand holes; (Dust is the main cause of trachoma, so try to avoid dust as much as possible!)
7. Corrosion, pour in corrosive solution for corrosion. The corrosion time is generally 1.8 minutes, and it needs to be adjusted according to different temperatures and the thickness of lines in different graphics and text; After the corrosion time is up, rinse with clean water to remove the corrosive solution; If the depth is not enough, it can be corroded again. (Depth not exceeding 0.5mm)
8. Wash off the photosensitive adhesive with plate washing water and complete the plate making process.
