Glue: 200-230g Water: 1000ml, boil in boiling water for 2 hours to fully dissolve the glue, add 25-30g of photosensitizer (ammonium butyrate) when the temperature drops to 30-50°C, and spread the glue evenly on On a metal plate, dry and ready to use. 5) Printing: SB750 type vacuum printing machine can be used for photosensitive printing. After the lamp is 60-90cm and the time is 40-80 seconds, it is placed in warm water for 1 minute and then placed in the color solution for dyeing. 6) Gloss preservation: After fully dyed brand, after drying, apply gloss retention paint with brush or spray gun (usually use eye brand baking paint or no-bake gloss retention paint). 7) Cut into.
