UV Printing VS Conventional Printing, Why to Choose UV Printing

UV Printing was almost unheard of until recently.  Many printers are now offering UV printing due to its many advantages over traditional printing.What are the advantages of uv printing? Please continue to read it.

1.What is UV Printing?

UV printing is a form of digital printing that uses ultra-violet lights to dry or cure ink as it is printed. As the printer distributes ink on the surface of a material (called a "substrate"), specially designed UV lights follow close behind, curing - or drying - the ink instantly. Originally developed for quickly drying gel nail polishes during manicures, ultraviolet light applications quickly expanded into industrial and commercial markets. Because the UV lights cure any printed ink immediately, the dots of wet ink do not get a chance to spread out once printed, resulting in much finer detail. In addition, UV cured inks are weather-resistant and offer increased resistance to fading. This curing process is more environmentally friendly as it produces few VOC’s, odor, and heat. UV curing also allows the flatbed printer to be used with nontraditional materials like acrylic or aluminum.


2.What is the difference between UV Printing and Conventional Printing?
The printing process is almost exactly the same for both conventional and UV printing; the difference comes in the inks and the drying process associated with those inks.
Conventional offset printing uses solvent inks – which are not the greenest option – because they evaporate into the air, releasing VOC's.  They often require additional spray powders to aid in drying.  Because they are absorbed into the paper, colors can become diluted and less bright. Depending on the papers character and weight, drying can add days to each job. Conventional inks must be absorbed by the substrate they are printed on therefore, you can not use them on materials like plastic, foil, or acrylics.
UV inks dry through a photomechanical process. The inks are exposed to ultra-violet lights as they are printed, immediately turning from a liquid to a solid with very little evaporation of solvents and almost no absorption of the ink into the paper stock. So you can print on virtually whatever you want when using UV inks!
Since they dry immediately and release no VOC's into the environment, UV printing is considered a green technology, safe for the environment and leaving an almost zero carbon footprint.
Of course, because UV inks dry on contact, they never smudge. And that means, no matter what type of paper you use, you will never need to add costly coatings to protect against smears and rub-offs.

3.FIVE REASONS TO CHOOSE UV PRINTING


1. WHEN ENVIRONMENTAL IMPACT IS A CONCERN

Because evaporation is minimized,  there are far fewer emissions of volatile organic compounds into the environment compared to other inks.
UV printing uses a photomechanical process to cure the ink versus drying through evaporation.
2. WHEN IT’S A RUSH JOB

Since there is no evaporation process to wait around for, UV inks don’t bring the down times other inks do while they dry. This can save time and get your pieces into the market much more quickly.
3. WHEN A SPECIFIC LOOK IS DESIRED

UV Printing is perfect for projects that need one of two looks:
A crisp, sharp look on uncoated stock, orA satin look on coated stockOf course, that doesn’t mean other looks can’t be accomplished. Talk to your printing rep to see if UV is right for your project.
4. WHEN SMUDGING OR ABRASION IS A CONCERN

The fact that UV printing dries instantly insures that regardless of how quickly you need the piece in hand, the work won’t be smudged and a UV coating can be applied to prevent abrasions.
5. WHEN PRINTING ON PLASTIC OR NON-POROUS SUBSTRATES

UV inks can dry directly on the surface of materials. Since it’s not necessary for the ink solvent to absorb into the stock, UV makes it possible to print on materials that wouldn’t work with traditional inks.
