Compared to other heat-cured ink in the uv printer, UV ink has the advantages of fast drying speed,low VOC content. However, in some substrate that is non-absorption, because of instantaneous drying of UV ink, sometimes may lead to UV ink's adhesion is not strong.How to enhance the adhesion of UV ink ?
1. Increase the power of the UV light curing lamp
2. Reduce the printing speed of uv printers
3. Reduce the thickness of uv printing ink layer
4. Extend uv print curing time
