Squeegee Force & Pressure Distribution
A misaligned squeegee can lead to poor print quality, inconsistency, and considerable
product defects, increasing costs and product waste. The I-Scan force and pressure
measurement system is a key diagnostic and machine set-up tool for balancing squeegee
pressures. The system's minimally intrusive sensors can be positioned under the screen or
squeegee blade to adjust blade height, pressure and tightness, ensuring the desired
pressure distribution along the length of the blade is achieved.

 |
The system allows for real
time viewing of the pressure along the squeegee blade and can also capture and display
the pressure pattern from the entire print stroke as the blade traverses the screen during
the printing stroke cycle. If the squeegee is unbalanced during the stroke, alterations can
be made and new measurements taken. Using this system, an unbalanced squeegee blade
can be detected prior to use, saving your company money and time. With the help of
Tekscan's highly qualified sales and engineering support team, each system may be
configured to meet your specific needs. |
