Screen printing, water and oily, what is the difference between the plastic material on the water or oily?
Water based ink is water-soluble ink, ink surface tension is relatively high, the substrate surface tension requirements are relatively high, adhesion is not oily, silk screen good
In addition, the choice of plastic screen printing ink depends on the plastic material, depending on what kind of plastic and what kind of ink needs to be printed
Oily silk screen is the use of solvent based ink, ink surface tension is relatively low, the substrate surface tension requirements are low, adhesion is easy to achieve, in addition, the color is better
