Optical Variable Ink - A Leap in Printing Innovation

Optical variable ink, as an innovative functional material in the fields of printing, packaging and anti-counterfeiting, is unique in that it uses the principle of optical interference to realize the change of color with the observation angle. This technical principle gives optical color-changing inks excellent anti-counterfeiting performance, making them widely used in many industries. In the field of packaging, optical color-changing inks can not only enhance the visual appeal of products, but also effectively prevent counterfeit products and protect consumer rights. In addition, it also shows great potential in the fields of paper products, plastic products and electronic products.

In offset printing technology, the application of optical chromic ink is particularly prominent, by adjusting the ink thickness, rich color changes can be achieved, and the aesthetics and uniqueness of the printed matter can be enhanced. At the same time, a reasonable selection of viewing angles is crucial to ensure the printing effect.

It is worth noting that the color change of optical color-changing ink is based on the principle of optics, will not fade over time, and is harmless to the environment and human health under the premise of not containing harmful substances. To sum up, optical color-changing inks play an important role in the modern printing and packaging industry due to their unique color change effect, excellent anti-counterfeiting performance and wide range of applications.
