What is a UV inkjet printer？

1. What is a UV inkjet printer?

UV inkjet printer is a non-contact high-speed printer. Under the control of software, it uses UV ink to print content on various materials and products through piezoelectric nozzles.

2. The printing principle of UV inkjet printer

The UV of UV ink is the abbreviation of ultraviolet in English. It can be dried quickly by the ultraviolet light of the curing lamp. After curing, the UV ink has a concave-convex feeling, and has high hardness, high gloss, high adhesion, washing resistance, and scratch resistance. , solvent resistance, green environmental protection and other characteristics, and easy to maintain, not easy to block the nozzle.

The UV inkjet printer is a high-resolution inkjet printer, which uses on-demand inkjet technology for printing, and the resolution reaches 300-1200DPI.

The piezoelectric nozzle of the UV inkjet printer consists of 128 or more piezoelectric crystals to control multiple nozzle holes on the nozzle plate. When the drive board outputs a series of electrical signals to each piezoelectric crystal, the piezoelectric crystal is strong. Under the action of the pulse voltage, deformation occurs, resulting in a reduction in the volume of the ink chamber of the nozzle, so that the ink is ejected from the nozzle and falls on the surface of the printing product. Through dot matrix control, we can obtain the desired text, numbers, graphics and other effects.

3. Application range of UV inkjet printer

Since the UV inkjet printer is non-contact printing, it is not limited by the material, and can realize inkjet marking on various materials, including plastic, metal, wood, tile, glass, leather, acrylic, etc., even irregular surface of the object.

UV inkjet printer does not need plate making, it can print text, database, variable serial number, variable two-dimensional code, barcode, GS1 code, UDI code, random code, drug supervision code, and pictures in various formats, especially suitable for ” The large-scale application of the “one item, one code” solution also meets the import and export of a large amount of data, and meets the needs of various printing content of users.

Fourth, the advantages of UV inkjet printer

1. Good effect, good adhesion, high resolution, no words or colors, beautiful and clear;

2. The speed is fast, the conveyor belt speed is 0-300 meters per minute, and 40 products can be sprayed per minute;

3. It is widely used and can be printed on various materials;

4. Traceable source, can spray dynamic QR code, bar code, date, etc., applicable to the solution of one code for one thing;

5. More environmentally friendly, without solvents, UV ink can pass ROSH, MSDS environmental testing and verification, and can be used in food, medical and other industries;

6. Low cost, no need for plate making, and the cost of consumables for UV inkjet printers is much lower than that of traditional printing methods;

7. Strong functions, support language editing, multiple languages, multiple picture formats, and configure multiple intelligent communication interfaces;

8. No clogging, only simple maintenance, UV ink is not easy to clog the nozzle.

Five, UV inkjet printer application industry

At present, UV inkjet printers have been used in card making, tags, labels, bottle caps, printing and flexible packaging, lighters, hardware accessories, brake pads, beverage dairy products, food, daily necessities, cosmetics, pharmaceutical health products, medical equipment, building materials industry, electronics, etc. Industry, battery industry, stationery industry, carton printing industry, seed fertilizer industry, etc. are widely used.
