Screen printing machine - printing accuracy is not stable

　　Problem performance: the printing pattern or text is blurred and not aligned, especially when high-precision screen printing on small batches of centrifugal tubes.

　　Cause analysis: 

　　1. the mechanical parts of the screen printing machine are loose, resulting in inaccurate transmission and positioning.

　　2. Ink viscosity does not meet the requirements, affecting the clarity of the pattern.

　　3. The photoelectric positioning system is not calibrated properly, failing to accurately detect the position of the centrifuge tube.

　　Solution:

　　-Check the mechanical parts of the equipment regularly and tighten loose screws or other connectors.

　　-Adjust the ink consistency according to the material of the centrifugal tube and screen printing requirements to ensure its fluidity and adhesion.

　　-Calibrate the photoelectric positioning system and ｒｅｐｌａｃｅ deteriorated sensors if necessary.
