During the production of ink, foam problem cause ink factoriesloss. Excessive foam will remain in the ink, affecting the performance and quality of the ink, resulting in its fluidity, adhesion, resistance to reduce the quality of the product.

There are many factors contributing to the foam:

1. Viscosity, resin and additives may cause ink surface tension to improve so that the bubble can not fade.

2. Substrate surface adhesion dust and oil stains and other substances

3. Printing speed is too fast or uneven
