2. INTRODUCTION
The use of digital UV printing is certainly a hot topic in the printing world right now.
It is the fastest growing sector of digital inkjet printing and more sustainable than
conventional printing.
UV printing technology offers users direct-printing capabilities onto a virtually
limitless range of three-dimensional media allowing quick and easy product
customisation . The UV ink is printed directly onto the substrate and when the inks
are exposed to UV light they turn from a liquid, to a solid instantly.

3.  What is UV Printers ?
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, specially designed UV lights
follow close behind, “curing” or “drying” the ink instantly.

4. UV printing is similar to traditional printing in the fact that it uses ink.
But unlike traditional printing in which the ink dries absorbs into the
paper and evaporates into the air, UV inks dry from being exposed to
ultra-violet lights that almost instantly turn the liquid ink into a solid.

6. BENEFITS OF UV PRINTING
 Print on a far broader range of substrates.
Unlike many other printing processes, UV-curing bonds the ink to
almost any surface. I’ve had conversations with operators who’ve printed on some
pretty unusual surfaces — from hand-made canvas and CD’s to concrete, wood,
metal, plastic and ceramic tiles. I even heard a story involving toast. It worked!
Open the door to a new world of creative possibilities.
The versatility of UV printers offers huge creative potential for your
business and clients. Use UV printers for indoor, outdoor and backlit signs,
POPs, posters, vehicle wraps, building wraps, cabinets, etc.
Faster drying time means faster production speeds.
Don’t discredit this technology as “niche” just because it offers so
many ‘creative’ possibilities. The UV process is still made for output and can
pump out sign graphic production with impressive speed and accuracy. UV inks
cure almost instantly, depending on the ink color and intensity of the UV light.
This translates into high operating speeds

7.  Print multiple color layers at the same time.
UV flatbed printers keep the media stationary and instead the
gantry, which holds the print heads, moves over the media. This allows
for multiple layers of printing simultaneously including white ink or
spot varnishes on highlighted areas of the media
 Reduce a lot of time-consuming finishing work.
Most UV-printed output doesn’t require laminating which
reduces costs and production time. And flatbed UV printers can
print directly onto rigid substrates like DiBond and Sintra which
eliminates the time and cost of mounting
You’ll even save on your electricity bill.
Latex printers use heat to cure the ink and draw a large amount of
power to create this heat. This power consumption may very well offset any
‘green’ advantages of eco-friendly inks. Not so with UV printers which use
either mercury/quartz or LED lights for curing, rather than heat.
Mercury/Quartz lamps last around 600 hours but LED are the most eco-
friendly, lasting up to 10,000 hours without using a lot of powe

8. ADVANTAGES AND DIS ADVANTAGES OF UV PRINTING
 ADVANTAGES
1. No need to add any solvent, the speed of ink curing is fast.
2. Printing quality is better and vairous media can be printed
3. With nice glossiness,it only requires partly varnishing.
4. Vairous printing effects with special treatments such as refraction,
grinding and Zou Wen .
 DISADVANTAGES
1. The printing process is complex with UV lamps.
2. While using UV ink printing, if the ink cannot be dried totally, it
will do harm to human bodies.
3. The adhesion is bad,only with coating, it can provide nice
adhesion.

9. Conventional Printers V/S UV Printers
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!
