How to improve the degree of curing of UV inks, HYUNVAN UV PRINTER FACTORY suggest you start from the following aspects:
1) Increase the power of the UV curing lamp: On most substrates, increasing the power of UV curing will increase the adhesion of the UV ink to the substrate. This is especially important in multi-layer printing: when applying the second layer of UV paint, the first layer of UV ink must be completely cured. Otherwise, once the second layer of UV ink is printed on the substrate surface, the bottom layer of UV ink will not have the opportunity to further cure. Of course, on individual substrates, over-curing can cause UV inks to be brittle when cut.
2) Reduce printing speed: Increasing the power of the UV lamp while reducing the printing speed can also improve the adhesion of UV ink. On UV flatbed inkjet printers, one-way printing (rather than printing back and forth) can also be used to improve the printing effect. However, on substrates that are prone to curling, heating and deceleration can also cause the substrate to curl.
3) Reduce the thickness of the ink layer: Because the adhesion effect is related to the degree of UV ink curing, reducing the amount of UV ink will promote the adhesion to the substrate. For example, in the process of large-area printing, the ink supply is too large and the ink layer is too thick. During UV curing, the surface layer of the ink is cured but the bottom layer is not fully cured. Once the ink has the phenomenon of false drying, the bonding force between the ink bottom layer and the surface of the substrate becomes poor, which will cause the ink layer on the surface of the printed matter to fall off due to surface friction during the subsequent processing.
4) Extend the curing time: It must be noted that the UV ink will be cured after printing. Especially in the first twenty-four hours after printing, this will improve UV adhesion. If possible, postpone the step of trimming the substrate until twenty-four hours after UV printing.
