Ways to improve the adhesion of UV inkWith other thermally cured inks in UV printers, UV inks have the advantages of fast drying speed and low VOC (volatile organic compounds) content. However, on some non-absorbent substrates, because the UV ink dries instantaneously, it sometimes causes the UV ink to easily have weak adhesion. Generally speaking, when the UV ink is not fully cured, we can observe that the UV ink is Poor adhesion to non-absorbent substrates.
