2. Operating Instructions
- Pretreatment of screen mesh Degrease mesh with degreaser, or roughen mesh surface with mesh abrasive paste. Roughening may be omitted for high‑mesh precision stencil making.
- Dry the screen for later use. Dry at 35‑40 °C (max. 42 °C), keep ambient humidity at 45‑55%.
- Coating sequences & drying ‑ Coating: Ink‑side 2 passes + Print‑side 2 passes; Dry: 35‑40 °C (max.42 °C), humidity 45‑55%, 10 min. ‑ Coating: Ink‑side 1 pass + Print‑side 3 passes; Dry: 35‑40 °C (max.42 °C), humidity 45‑55%, 10 min. ‑ Coating: Ink‑side 0 pass + Print‑side 1 pass; Dry: 35‑40 °C (max.42 °C), humidity 45‑55%, 10 min.
The net dry stencil thickness reaches approx. 8 μm. Coating procedure may vary for different industries. Multiple coating passes can achieve target stencil thickness.
- Exposure Determine optimal exposure energy by exposure step‑wedge film. If step‑wedge film is unavailable, test multiple exposure energies on one screen, select suitable energy according to wash‑out result and ease of development. After setting exposure energy, test exposure output periodically and adjust parameters accordingly. ‑ Insufficient exposure: poor solvent resistance and short print run life of stencil. ‑ Over‑exposure: deterioration of resolution.
Allow screen to rest for 1‑3 minutes after exposure.
- Development (Wash‑out) Wet both sides of screen with low‑pressure water (or soak for no more than 1‑2 min), wait 1‑2 min. Spray the print‑side continuously with fan‑shaped low‑pressure water until clear image appears.Note: Focus washing on print‑side. Excessive washing on ink‑side may cause pinholes and degrade edge sharpness. Keep water gun approx. 60 cm away from screen. Then gently rinse ink‑side for 1‑2 minutes. After confirming complete image wash‑out, rinse residual emulsion scum from both sides of screen.
- Post‑development drying Dry screen at 35‑40 °C (max.42 °C), humidity 45‑55%, for 20‑30 minutes.
- Screen inspection & repair For higher print‑run durability, perform post‑exposure (secondary exposure) under standard exposure unit.
- Block‑out the screen.
