UV Printing: Can You Afford not to Make the Investment?
We all know about how “green” the world has become. Well UV printing is an eco-friendly practice. Because of the polymerization method or cross link during the drying process, you have no solvents that are released or absorbed in the substrate as with conventional inks. This equates to no VOC’s (Volatile Organic Compounds), which make it much safer for you and the environment. Thereby making it more inviting to the large corporate America customers as well as the small print buyers looking for a “greener” printer.
Since UV inks are dried or cured with ultraviolet lights, drying time is eliminated. Unlike conventional oil based inks, UV dries instantly when the sheet passes under the light.
At that time, it turns from a liquid state to a solid. UV inks are not absorbed into the stocks, which means the ink film remains on top of the sheet. This also translates into much more vibrant print and visual effects. Conventional inks not only have to dry with evaporation, they will loose up to 50% of the initial ink film applied through evaporation and absorption. You cannot match the quality of UV inks on an offset sheet using the conventional process.
Other important advantages of instant drying with UV are the turn times in production and no marking or smudging on the finishing equipment or non-porous substrates. You now have the option to back up the job right away, no matter what the run length and/or send the job straight to the bindery. This will enable you to not only save valuable floor space in your building but also not have the worries of blemishes on a cutter or folder.
Ask yourself these questions again. How many times have drying issues been a bottleneck within your company? How much time and money have you spent on additional makereadies when the job was too wet to handle? Why do we have to do a second pass when overprinting metallic inks? Were these additional costs passed on to your customers or did you have to chalk it up to experience and try not to let it happen again? What about that plastic or foil job that sat there for days while you paced like an expectant father outside of a delivery room until it finally dried? Think how great it would be to not have these worries?
