How To Measure Screen Printing Mesh's Tension Using A Tension Meter

Here are the steps to use a tension meter to measure the tension of the screen printing mesh:
1. Preparation
Choose a suitable tension meter:
Choose the corresponding tension meter according to the material and specifications of the mesh. Common tension meters include mechanical tension meters and electronic tension meters. Electronic tension meters usually have higher accuracy and measurement range.
Make sure the tension meter is calibrated to ensure the accuracy of the measurement results.
Clean the mesh and mesh frame:
Before measuring, make sure the surface of the mesh and mesh frame is clean and free of impurities such as dust and oil. These impurities may affect the measurement results of the tension meter.
You can use a clean cloth or detergent to gently wipe the surface of the mesh and mesh frame.
2. Measurement steps
Install the tension meter:
Install the probe of the tension meter on the mesh. For mechanical tension meters, it is usually necessary to insert the probe into the mesh and then read the value indicated by the pointer; for electronic tension meters, contact the probe with the mesh according to the instructions and turn on the power.
Select measurement points:
Select multiple measurement points on the mesh to obtain a more accurate average tension value. The measuring points should be evenly distributed at different positions of the mesh, including the four corners, center and edge of the mesh frame.
Generally speaking, the more measuring points there are, the more accurate the measurement results will be.
To perform the measurement:
Press the probe of the tension meter gently on the mesh to ensure that the probe is in full contact with the mesh. Wait a few seconds for the tension meter to stabilize, and then read the measurement results.
For mechanical tension meters, directly read the value indicated by the pointer; for electronic tension meters, check the value on the display.
Record and calculate:
Record the tension value of each measuring point. Then, calculate the average of these measured values ​​as the average tension value of the mesh.
The average tension value can reflect the overall tension level of the mesh.
Analysis results:
According to the specifications and printing requirements of the mesh, judge whether the measurement results meet the requirements. Generally speaking, the tension of the mesh should be within a certain range to ensure the printing quality.
If the tension value is too high or too low, the tension can be adjusted by adjusting the tension adjustment device of the mesh frame or replacing the mesh.
III. Precautions
Operation specifications:
Strictly follow the instruction manual of the tension meter to avoid inaccurate measurement results due to improper operation.
When installing and using the tensiometer, be careful to avoid damaging the probe or affecting the measurement accuracy.
Measurement environment:
Try to measure in a stable environment to avoid changes in temperature, humidity and other factors that may affect the measurement results of the tensiometer.
If the measurement environment is unstable, the mesh and the tensiometer can be placed in the same environment for a period of time before measurement to adapt to the ambient temperature and humidity.
Regular calibration:
The tensiometer should be calibrated regularly to ensure the accuracy of the measurement results. The tensiometer can be calibrated using standard weights or other calibration equipment.
The frequency of calibration should be determined based on the frequency of use and accuracy requirements of the tensiometer.
