So, UV printing – what’s it all about?
For starters, it’s different from your conventional type of printing. The ink dries on the paper through a different process than traditional methods. UV inks – when exposed to ultraviolet lights turn from a liquid, or paste, to a solid – dry through a photomechanical process.
A huge advantage of UV printing is fewer emissions of volatile compounds into the atmosphere due to zero evaporation. The inks dry through a photomechanical process, and therefore don’t absorb into the stock.
A crucial factor to successfully printing with UV inks lies in exposing it to enough ultraviolet energy to cure the ink.
Environmental issues aside, there are many advantages to UV printing. The inks can dry on plastic, and other non-porous substrates, and because of the process outlined above, the ink solvent doesn’t need to absorb into the stock. Essentially, if the stock fits through the press it can be printed on. We can even print on wood veneer. As well as the advantage of printing on substrates such as plastic, UV printing has significant benefits when printing on uncoated stocks too. Conventional solvents in inks absorb very quickly into uncoated stocks so less of the solvents evaporate and the printed piece will have excessive dot gain, and therefore look fuzzy. The most important element of successfully printing with UV inks is: expose the UV ink to enough ultraviolet energy to cure it, while not making the substrate too fragile and brittle. As you would correctly ascertain, this is an incredibly tricky process. We have years of experience in getting the balance just right so our customers’ signs stand out – and positively glow – from the crowd.
