Problems with pipette silkscreen quality

　　Problem performance:

　　1. Printing pattern is blurred or unclear.

　　2. Too much ink penetration, resulting in blurred edges of the pattern.

　　3. Screen leakage or part of the pattern is missing.

　　Cause analysis:

　　-Insufficient screen tension or poor screen quality.

　　-Ink viscosity does not meet the requirements, too thin or too thick.

　　-Insufficient surface treatment of the pipette, insufficient adhesion.

　　Solution:

　　1. Regularly check the screen tension and ｒｅｐｌａｃｅ the screen with a high quality screen if necessary.

　　2. Adjust the ink viscosity according to production needs to ensure that its fluidity and adhesion is moderate.

　　3. Clean the surface of the pipette to ensure that it is free of dust and oil.
