Screen Printing Machines Troubleshooting

紹介

Even the best screen printing machines can have problems. Quick troubleshooting keeps production running and reduces waste. Knowing common issues and fixes saves time and money.

Common Problems and Solutions

1. Misaligned Prints

Cause: Screen or material moved during 印刷.
Fix: Tighten clamps. Check that the frame is secure and the table is level.

2. Uneven Ink Coverage

Cause: Ink too thick or squeegee pressure uneven.
Fix: Stir ink well. Adjust squeegee angle and pressure.

3. Blurred Edges

Cause: Screen not tight or too much ink.
Fix: Re-tension the screen. Reduce ink flow.

4. Ink Drying on Screen

Cause: Slow printing or high heat in the room.
Fix: Work faster. Lower room temperature. Use ink with slower drying speed.

5. Poor Color Registration

Cause: Wrong screen position or stretch.
Fix: Realign screens. Check for wear and replace if needed.

Preventive Steps

• Clean Screens After Each Job – Stops ink build-up.

• Check Squeegee Condition – Replace worn edges for sharp prints.

• Maintain Machine Level – Prevents print distortion.

• Store Ink Correctly – Keep in sealed containers away from heat or cold.

When to Call a Technician

If the machine makes unusual noise, stops moving, or shows electrical faults, stop work and call a trained technician. Trying to fix complex issues without skill may cause more damage.

Benefits of Quick Troubleshooting

• Less Downtime – Production stays on schedule.

• Better Print Quality – Consistent, sharp results.

• Lower Repair Costs – Small fixes prevent big failures.

Conclusion

Troubleshooting screen printing machines is easier with a clear checklist. By solving small problems early and maintaining the machine well, you keep printing smooth, fast, and profitable.
