Description

UV LED Inks

UV LED inks differ from traditional UV free radical inks in their formulation. Special consideration of photoinitiators and pigments in the formulation must be made to match the spectral output of the LED lamps. These special photoinitiators absorb at a higher wavelength as opposed to traditional photoinitiators and are typically more expensive. The spectral output of a LED lamp to cure UV LED inks is very narrow, 365 - 405 nm, as compared to a UV mercury system which operates from 200 - 700 nm range.

UV LED Curing

Because of the limited spectral wavelength, UV LED primarily operates in the UV-A zone and considered to be 'safe' because it is closest to visible light. However, prolonged exposure to
this energy can be dangerous. The UV-B and much of the UV-C spectrums of light are primarily used for germicidal and
sterilization purposes. Light produced at these wavelengths are not only harmful to microorganisms, but are also dangerous to humans and other forms of life that may come in contact with it.

Applications

UV-A type devices have been traditionally used in applications such as counterfeit detection or validation (currency, identification documents, etc). The actual wavelengths used are in the 390 nm - 420 nm range. As a result, these type of LED's are readily available from a variety of sources and are considered the least expensive.
The middle UV-A LED area 350 nm - 390 nm are for curing both commercial and industrial materials such as adhesives, coatings and inks. There are many advantages over traditional curing technologies due to increased efficiencies and lower cost of ownership. Although the cost of this technology is greater, advances in manufacturing and demand are driving prices down.
The lower UV-A and upper UV-B ranges 300 nm - 350 nm are the most recent introduction to the marketplace. These units can be used in a variety of applications including UV curing and biomedical applications. There is

a significant overlap in all three of the UV spectrum ranges, so consideration must be made in what is best for the application.

The lower UV-B and upper UV-C ranges 250 nm - 300 nm, is still in it's early development stage. However, there is a great interest in these LED's in air and water purification systems.

More compact than mercury systems
Low voltage
No shutters or glass quartz
Consistent and immediate UV output over operating life
No UVC and therefore no ozone emitted, eliminating need for exhaust
Does not contain heavy metals (mercury)
Longer life, + 20,000 hrs as compared to 1,500 hrs on a standard UV mercury lamp
Easier to convert materials that are heat sensitive
LEDs are more efficient than mercury bulbs

Cost

UV LED inks and curing units are more expensive than current UV technologies. In the screen printing arena, UV LED curing is a standard on most UV platforms. Many press manufacturers now offer UV LED as an option if a customer is purchasing a new press. For customers looking to take advantage of the latest technology, many UV LED manufacturers are offering retrofits to existing presses. UV LED curing solutions for both new and retrofit narrow web presses, offer higher yields and decreased operating costs for increased profitability.

Usage
Step 1, Clean the substrate and print it until dried.
Step 2, Mixing the reducer with ink 3% to 5%.
Step 3, Printing the ink with semi-automatic or automatic screen printing machine by 200mesh to 350mesh.
Step 4, Dry the printed object by UV-LED cured machine wave length 395um, power depend on the ink color and thickness.

Store

Keep dry and seal, stay far away from fire and heating.
Seal the package if could not use out in one time.
Due to sunlight and lamplight with UV, avoid light anytime and anywhere.

UV LED Benefits for Screen Printing

YC Science & Technology Printing Co. Ltd was established in 2005 to help ten-thousands of Chinese and foreign enterprises to develop screen printing and water transfer process. We are located in Guangdong Shunde this rich land, is the high-tech enterprises with trade and industry in one, which won the the title of "Guangdong high-tech enterprises," ,and get strong support from the state.
In recent years, successfully developed Metallic printing technique and offer whole set of production equipment, after our vigorously promote, is now widely implemented to the United Kingdom, Russia and South America and other countries.
UV-LED curing technique is also one of the hi-tech technology developed by YC,which solves the limitation of the past nature drying ink and glue drying drying slow, LED curing is speed up the production, e.g. the production speed of 8 hours in the past, now is able to completed dry in less than 10 minutes; Compared to traditional UV drying technology more energy efficient and environmentally friendly.
YC can also help customers customized prints tattoo stickers and Gold decals/Gold decal etc, such as glass cups, bottles / wine bottles, thermos cup, gift boxes, sports equipment decals and so on.
LED curing non-treatment screen printing ink for plastic including PET / PVC / ABS / acrylic etc, and metal, painted surface, ect. Dry faster, stronger adhesion.
