UV Printing

The best feature of UV printing is that the UV inks can dry on plastic, foil and other non-porous substrates. Because the inks dry through a photomechanical process it is not necessary for the ink solvent to absorb into the stock. Basically, any substrate able to pass through the press can be printed on.

 

In addition to being able to use multiple stocks and substrates, UV printing also offers significant advantages when printing on uncoated card stocks as well. The solvents in conventional inks absorb very quickly into uncoated stocks. Because of this, less of the solvents evaporate and the printed piece tends to have excessive dot gain and will look muddy or too full.

 

Since UV inks set very quickly after exposure to UV light, the ink doesn’t absorb into the paper and the ink dot is left sitting on the surface of the uncoated sheet leaving a crisp well-defined dot, giving sharper images with more vibrant color UV printing is also more resistant to scratches, wear and tear, and sun exposure than its traditional printing counterparts.

 

One final advantage of UV printing is that the ink doesn’t set by solvent evaporation.so there're fewer emissions of volatile organic compounds into the air, which can only be good for the environment.
