Optically color-changing pigments are embedded into the labels to create anti-counterfeiting features that are difficult to replicate. At the same time, through customized color-changing designs, companies can stand out among many competing products and enhance brand recognition.
In banknote security, optically color-changing inks are often used on specific design elements such as numbers, patterns or strips. Optically color-changing pigments are an important part of modern banknote anti-counterfeiting technology. They use high-tech means to achieve anti-counterfeiting features that are both beautiful and difficult to copy, which is one of the effective means to combat counterfeit currency.
Optical pigments are widely used in many fields due to their unique color-changing properties and high anti-counterfeiting properties, including pharmaceutical packaging, cigarette packaging, invoices, etc. Effectively enhancing the safety, anti-counterfeiting and aesthetics of these products is an important part of modern anti-counterfeiting technology.
Based on the understanding of color optics, Sunflower Chemical has an advanced film color development and design software system that can perform film structure design simulation, color feature evaluation, manufacturability analysis, and color product customization services.
As a high-tech anti-counterfeiting material, one of its core characteristics is the extreme concentration of particle size peaks. This characteristic means that the size distribution of pigment particles is extremely narrow, and almost all particles are concentrated in a certain size range, forming a clear and sharp particle size peak.
Under a microscope, the particles of optical anti-counterfeiting pigments show clear boundaries and irregular shapes. This inconsistent shape not only makes the pigment visually more delicate and uniform, but also makes it difficult for counterfeiters to replicate its unique optical properties through conventional means, thereby greatly increasing the difficulty of counterfeiting.
Optical anti-counterfeiting pigments are rapidly occupying various industries due to their super applicability. They always appear in different forms in unexpected places. Because it can be square, long, round, text, or even a specific pattern. It all depends on imagination. Generate a set of anti-counterfeiting passwords that belong to you.
Sunflower's optical pigments have a perfect diameter-to-thickness ratio and excellent reflective surface. With its high-saturation color-changing effect, it far surpasses traditional pearlescent chameleon pigments and can be called a perfect "two-dimensional product". Each color is unique on the market, providing a reliable guarantee for anti-counterfeiting.
Nanotechnology, precision synthesis methods, surface modification and coating and other advanced processes not only improve the performance and application scope of optical pigments, but also promote technological innovation and sustainable development of the pigment industry.
Because it is thinner than traditional optical pigments, more pieces can be obtained under the same weight, so only a little bit is needed to achieve excellent covering and discoloration effects.
