Typical Applications

Usage Instructions

• ‌Pre-Press Preparation‌:
  Ensure material surface tension ≥38 dyn/cm to guarantee adhesion.

• ‌Dilution Ratio‌:
  Adjust according to printing speed and seasonal conditions. A 5%-15% thinning agent addition is recommended.

• ‌Viscosity Control‌:
  Maintain viscosity within the optimal range to avoid over-dilution or excessive thickness, which may affect print quality.

• ‌Drying Settings‌:
  Optimize hot air temperature (recommended 50~65°C) to ensure thorough drying and prevent misregistration.

• ‌Storage & Usage‌:
  Stir thoroughly before use. Conduct small-batch test prints for performance verification if left unused for extended periods.
