Technical Guidelines & Operating Instructions

Follow these recommendations to achieve optimal printing results and ink performance.

Core Process Parameters

Standard Viscosity: 20-30 seconds (Zahn 4# cup)
pH Control: 8.5 - 9.5
Substrate Requirement: Surface Tension ≥ 38 dyne

Operating Recommendations

Dilution Ratio:

Suggested water addition is less than 10%, depending on ambient temperature and humidity.

Anilox Roller:

Recommended 400-600 line screen for optimal ink transfer.

Drying Temperature:

Set dryer between 60℃-80℃

Machine Stoppage:

If stopped for more than 30 minutes, flush the ink path thoroughly with water.

Important Warning: Do not over-reduce with water. Excessive water addition will cause viscosity breakdown and adhesion failure. For drying speed adjustments, please consult technical support for specialized additives.
