UV offset ink is one kind of ink can print on both paper and pvc,which different from the normal offset ink.So uv offset printing ink has many kinds of benefits.

UV offset ink is a special type of ink used in offset printing that cures (dries) when exposed to ultraviolet (UV) light. This is different from traditional offset inks which dry through evaporation.

The four-color printing mode is a color registration mode used in color printing. It uses the principle of color mixing of three primary colors of color materials, plus black ink, and a total of four colors are mixed and superimposed to form the so-called "full-color printing". The four standard colors are: C:Cyan = cyan, also known as 'sky blue' or 'blue'; M:Magenta = magenta, also known as 'magenta'; Y:Yellow = yellow; K:blacK= Black, although some literature explains that the K here should be Key Color (positioning and registration color), but it is actually confused with the concept of positioning and registration used in plate making. The abbreviation here uses the last letter K instead of the beginning B to avoid confusion with Blue. The CMYK mode is a subtractive color mode, and the corresponding RGB mode is an additive color mode

UV flexo printing is a type of flexographic printing that uses ultraviolet (UV) light to cure the ink.

Flexographic printing is a type of letterpress printing that uses a flexographic printing plate and transfers ink through an anilox roller.

Flexographic UV inks are mainly composed of prepolymers, reactive diluents, photoinitiators and sensitizers, pigments, and additives. According to the requirements of different printing materials, these components are reasonably coordinated to make the flexo UV ink achieve the best performance.

At present, UV ink is widely respected by printing manufacturers. And UV ink is an economical and environmentally friendly ink, which is the direction of ink development in the future. The types and characteristics of UV inks are introduced below.
