Mimaki UV ink is a type of ink used for UV curing printing, featuring the following characteristics and related knowledge:
Features and Advantages:
- Good environmental performance: Mimaki UV ink It belongs to low VOC ink and uses ozone-free LED - UV light curing, which is friendly to environment and user health, and some products have obtained the "Greenguard Gold" certification.
- Fast curing speed: It can be cured and attached to the or substrate immediately through UV radiation, and the printed matter is dry as soon as it is printed, which can meet the needs of short delivery times.
- Strong compatibility: can print on a variety of non-absorbent materials, such as plastics, glass, metal, etc., and can also print bright colors on thermosensitive materials.
- High printing quality: Mimaki UV ink can achieve high-speed printing at 60m²/h, and the effect is bright and delicate. With Mimaki's control technology, smooth gradient printing can be achieved.
- Wide range of applications: There are hard and soft ink types, hard ink for hard material surfaces, and soft ink for film and other flexible materials; white and transparent inks can achieve a variety of printing effects, and can also achieve embossing printing through combination with primer.
Mimaki UV ink Class:
- By performance: There are hard inks such as LH - 100, suitable for hard materials such as tiles and metal; soft inks such LUS - 120, LUS - 350, used for soft materials such as PVC reflective film and carpet leather.
- By color: There basic colors such as CMYK, as well as extended colors such as light red, light blue, etc., and there are also special color inks such as white ink, ink, primer, varnish, etc., which can be combined into a variety of printing schemes.
Mimaki UV ink Applicable Equipment and Materials:
- Applicable equipment: models of Mimaki UV printers, such as LUS-120, LUS-150, LUS-170, LUS-210, UJF - 7151plusll3, etc.
- Applicable materials: including but not limited metal, glass, ceramics, acrylic, PVC, PET, wooden boards, leather, film and other materials.
The curing principle of Mimaki UV ink：
The curing principle of Mimaki UV ink is based on photochemical reaction. Its main components include oligomer, monomer, photoiniti, and pigment, etc.
When the UV ink is exposed to ultraviolet (UV) light of a specific wavelength, the photoinitiator in the ink absorbs photon energy and transitions from the ground state to the excited state. The excited photoinitiator will undergo reactions such as cleavage or hydrogen abstraction, generating active species such as radicals or cations. These active species initiate the polymerization reaction of oligomers and monomers, causing the ink to rapidly transform from liquid to solid, thus achieving the c of the ink on the surface of the substrate.
Mimaki's UV curing system typically uses LED-UV light sources, which can emit specific wavelength ultraviolet light for ink curing with precision. It has the advantages of fast curing speed, low energy consumption, and long service life, and can efficiently solidify UV inks on substrates, forming strong and high-quality printed patterns and coatings.
