What is UV Printing?
While ultraviolet printing is only available for commercial use, it has risen to the top for the most popular ink choice for wide format printers. As the name implies, ultraviolet inks will not dry unless it is cured, but once exposed to UV light it dries very quickly. As projects come out of the printer, a burst of ultraviolet light cures the ink, insuring that it comes out completely dry and ready to display.
UV ink is preferred for lawn signs because the results are crisp and vibrant colors that can catch and reflect light, making it ideal for outdoor usage. It's environmentally friendly and safe as well as environmentally able to withstand intense weather.
That's awesome, but let's get to know UV ink even better. What are the disadvantages of UV inks? As we had aforementioned, the ink requires special UV lighting curing. Although not hazardous, those who operate the printer should avoid getting the ink on his or her skin as it could cause skin irritation. As with everything there has been a few cases of allergic reactions, but this is not common. In fact, overall, UV ink is considered pretty harmless. This is one of the main reasons why US printing becoming so popular and so many corporations are making the switch from solvent ink printers. In comparison, solvent printing is the more toxic and hazardous of the two, especially when it becomes airborne.
Another small negative about UV ink is that spills are stubborn and difficult to clean up. Rubbing alcohol does a decent job at removing ink from skin but because it is such a good versatile ink, it does stain certain materials.
