UV flexo printing ink and its process technology are constantly improving and perfecting, and new varieties and new equipment are constantly emerging. The application of UV flexo printing technology needs to pay attention to some problems.
1. UV light
UV flexo inks of different colors have different abilities to absorb UV light. The power of UV lamps needs to be allocated according to different colors to ensure reasonable drying of UV inks of various colors and save energy.
2. Rubber roller
The rubber roller must be resistant to UV ink
3. Anilox roller
When using UV flexo ink, the mesh angle of the anilox roller is preferably 30° or 60°.
4. Plates
Although the flexo printing plates used can basically be used for UV flexo printing inks, it is better to choose plates with better resistance to UV inks,

UV flexo printing ink should be strictly protected from light and heat. The storage temperature should be controlled at 5 ℃ ~ 30 ℃
