What is UV LED printing?
UV LED printing is a common printing process,
mainly using ultraviolet light to solidify ink, which directly uses UV ink for printing.
With UV curing lamp to irradiate products,
a variety of ink instantaneous drying, making the color of four-color overlay more intuitive in front of consumers.
What are the characteristics of UV LEDprinting?
1. Accurate Setting
The overprint accuracy of UV printing is very high, as long as the position of the overprint is adjusted well,
the resulting pattern will not be out of shape and will not lose material.
2. The printing effect is realistic
UV LEDprinting uses UV ink to transfer printing, and the color after printing is very bright and lifelike,
many 3D pattern printing will use this process to transfer printing.
3. High Price of Ink
UV ink has the advantages of instantaneous curing and good conjunctival properties,
although its price is high.
The price of UV ink is more than 3-5 times that of other inks, a
nd the price of Polish used is more than 2 times that of water-based polish.
4.There are two major hazards in UV printing.
Harm of UV Light Source
UV ink must be cured by UV light source.
As we all know, UV light source is a kind of ultraviolet ray, which can cause damage to human skin and eyes.
When printing, as long as the operator does not face the UV lamp for a long time, he will not be exposed to ultraviolet radiation.
It is suggested that the operator should wear a good mask and eye mask to avoid radiation.
Harm of UV Ink to Human Body
Although UV ink is called environmentally friendly ink,
it contains acrylates that stimulate the human body to put into the skin.
If you are exposed to UV ink for a long time,
it is likely that there will be skin allergy symptoms, serious cases will be redness and peeling.
Operators should wear protective clothes, gloves, eye masks and face masks in production,
and reduce the contact between skin and ink.
If skin is accidentally stained with UV ink, clean it with soapy water.
5.Application fields of UV printing
Compared with ordinary printing, UV printing has the characteristics of bright color, special printing materials,
novel products and broad market prospects.
Applicable to high-end personal business cards,
gift packaging inside and outside, business picture albums, special desktop calendar, label printing and other product areas.
