Anti counterfeiting ink

The magnetic ink uses magnetizable pigments, such as Fe3O4 and Fe2O3. Most of these particles are needle-like crystals smaller than 1 μm. After magnetic field treatment, it is easy to achieve magnetic alignment and obtain higher residual magnetism. The ink made after adding to the ink shows magnetism and becomes a magnetic ink. Magnetic ink is widely used in anti-counterfeiting documents such as bank cards, checks, credit cards, ID cards, passports, etc. Now most companies only have black and brown two colors.But our engineers have developed three new colors: blue, red，yellow and green in 2019. These colors have been tested and received very good feedback.We are continuing to develop other colors, if you want to customize other colors, please contact us, we are very happy to serve you.
