The characteristic of UV ink is oily ink (also known as ink), and it is mainly used in UV machines. Abbreviated as UV ink.

UV ink dries immediately: UV ink has the characteristic of selective absorption of UV light. Drying is influenced by the total energy of UV light source radiation and the distribution of light energy at different wavelengths. Under the irradiation of UV light, the UV ink photopolymerization initiator absorbs photons of a certain wavelength, excites them to the excited state, and forms free radicals or ions.

Then, through intermolecular energy transfer, the polymerized prepolymers and photosensitive monomers and polymers become excited states, resulting in charge transfer complexes. These complex particles continuously crosslink and polymerize, solidifying into films

UV ink due to its unique internal structure. Cannot see light and high temperature. So UV ink bottles are generally black. The ink system inside the UV machine is mainly opaque black.

The curing speed of UV ink is actually related to color. Some colors in UV ink absorb more ultraviolet rays, while others absorb less, resulting in inconsistent curing speed, but only slight differences. It does not have a significant impact on the actual printing process.

The color state printed by UV ink using a UV printer is matte because the curing speed of UV ink is very fast, and it will solidify after printing before it becomes smooth and smooth. Due to the diffuse reflection of light on the surface of UV ink, the gloss becomes difficult to appear (Matte: Reflected light is "diffuse reflection", without glare, not dazzling, giving people a stable and elegant feeling. Bright light has a smooth surface, and the reflected light reflects on the mirror, giving people a bright and gorgeous feeling.)

The concentration of black in UV ink is too high, which can lead to poor adhesion and curing. Due to the high carbon content in black UV ink, carbon absorbs the ultraviolet rays in the UV lamp, resulting in a decrease in the amount of ultraviolet rays that can truly participate in the curing reaction.

UV ink has a high usage rate of white ink during use (white ink not only adds white color to the pattern, but also has a more important use of isolating the color of the pattern from the color of the material to avoid color mixing)

UV ink has a slight impact on its viscosity with temperature changes, with higher temperatures resulting in lower viscosity. So the color hardness printed in the early morning of winter is slightly higher, while the color hardness printed in the noon of summer is slightly softer (similar to thermal expansion and contraction)

UV ink has a high viscosity and is generally suitable for industrial grade printers (such as Ricoh nozzles, Seiko nozzles, Konica nozzles, Kyocera nozzles, Toshiba nozzles, and other industrial grade nozzles).
