So far, many people don't know much about UV printers, whether the products made by UV printers are environmentally friendly, and whether they are harmful to human body. In fact, we all know that UV printer mainly realizes the printing of patterns through ink-jet, and it itself belongs to the type of machine, which does no harm to the human body. It is mainly the problem of ink consumables. Let's analyze the following: is UV ink harmful to the human body.

1、 Classification of UV color printer inks

(1) Solvent ink (cured by solvent volatilization);

(2) Thermal sublimation ink (cured by heating);

(3) Water based ink (cured by heating);

(4) UV ink (cured by UV).

2、 Analysis of harmful components

Solvent, thermal sublimation and water-based ink all contain a large amount of solvent and have a strong smell. Solvent is harmful to human body. Long term inhalation of solvent odor will cause chronic poisoning and have a certain carcinogenic rate. Therefore, long-term operation of these three inks will do some harm to human body. UV ink does not contain solvent and is mainly cured by UV.

Main components of UV ink: 1 Toner; 2. Resin; 3. Photoinitiator.

Advantages of UV ink: it does not contain solvent, that is, it is dry after beating, and the smell is small.

3、 Analysis from the use of UV printer.

(1) UV printer is a new type of digital color printing industry, which will not produce waste gas, waste water and zero pollution;

(2) UV printer adopts UV ink, which does not contain VOC volatile materials, tasteless and formaldehyde free;

(3) UV printer has no solid waste and has a wide range of applications.

To sum up, UV ink is the ink that does the least harm to human body in inkjet printers and is environmentally friendly.
