Best Screen Requirements

1. Keep the tool clean and ready for use. The plate making room should be free of dust.
2, check the screen tension. All multicolor overprint screens need the same tension.
3. Fully degreasing: Use a soft brush and a certain pressure to clean the water.
4, drying at a temperature below 40 °C.
5, according to the manufacturer's recommended method, with two hours ahead of the photosensitive glue with good.
6, using a clean, slightly rounded edge of the sizing device for gluing, gluing area is at least 10% smaller than the inner diameter of the frame.
7, when gluing, we must first start from the printing surface. The number of gluing depends on the solid content of the sensitized adhesive, the viscosity, the number of screen meshes, and the desired screen thickness.
8. When drying the screen, the printed surface should be placed downward (avoiding photographic fluid flowing back to the ink surface).
9, for fine-line printing and halftone printing screen, after each drying need to be painted on the printed surface once or more photosensitive adhesive, until the printing surface of the photosensitive layer formation.
10. Keep the glass vacuum blanket of the exposure machine clean. Check the film is correct? Does the film surface fit on the screen? Does blackness meet the requirements and is it placed correctly? And make the exposure machine has enough time to reassure.
11. Set the correct exposure time and keep the record. Every three months or when the exposure decreases, the exposure time should be tested and adjusted to correct. 12. Keep the exposed screen away from the light source (daylight, incandescent lamps).
13. When developing, use appropriate pressure water for cleaning and development. In particular, the ink surface should be fully cleaned and cannot be flushed until the surface is not slippery. Insufficiently exposed photographic film will be stripped after cleaning.
14. Use a clean, soft paper, a clean cloth, or a vacuum cleaner to remove excess moisture.
15. Use a suitable patch of material to repair the screen.
16. Write all parameters to the mesh: thickness, exposure time, date, and name.
