Magnetic nano offset printing ink

Abstract

The invention relates to novel black or brown magnetic falsification-resistant offset printing ink comprising the following components: magnetic nano powder, binders, solvents, lubricating agents, defoaming agents, levelling agents, drying agents, mineral oil, etc. The offset printing ink is characterized in that the used magnetic powder body is formed by one or more of self-made ferrite nanoparticles (with mean grain size between 10nm and 200nm) with chemical formula of MFe2O4 (M=Fe, Co, Ni, Cu, Mg, Zn, Mn and other bivalent cations or combination thereof) or AxB1-XFe12O19 (A=Fe, Co, Ni, Cu, Mg, Zn, Mn and other bivalent cations or combination thereof; B=Ba, Sr, Pr or combination thereof) or nano-scale iron, cobalt and nickel or alloy powder thereof. The labels printed by the magnetic printing ink present black or brown characteristic and simultaneously have magnetic falsification-resistance function. The printing ink has diversified falsification-resistance functions and high technical content, is difficult to copy and can be used for falsification-resistant printing of outer packages of commodities, valuable securities, labels, dockets, etc.

AI Technical Summary

Benefits of technology

This patented technology improves upon existing technologies used on specialized items like security documents or credit cards through adding nanoperoxides made from natural ferrous metal (NFO). These techniques have several advantages such as being less expensive compared with other methods but still providing effective antifrauding capabilities due to their ability to hide hidden data during manufacturing processes without compromising its effectiveness against counterfeiters. Additionally, these properties can also help prevent forgery when applied onto valuable merchandise. Overall, this innovation makes them easier to verify if an item works properly and reduces costs associated therewith.

Problems solved by technology

This patented describes various ways to make magneistatic ink from traditional ingredients like Iron Oxides Pigments. These techniques involve adding small metal flakes mixed together during preparations, which makes the resulting product difficultly replicated without compromising its original properties such as authenticity. To solve this issue, researchers were able to create an antimony based on Magnet Oil called Ferrooxyn®. While some improvements over existing ones may still exist, they require further development before becoming commercially viable due to safety concerns associated with certain compounds commonly found inside commercial banks' stockpiles.
