UV sensitive fluorescent ink shows clear 2 color of red and blue when being excited only by uv light. but it shows no effect under general visible rays.
it shows good brightness under both long wave length (365nm) and short
wave length (254nm). it be named black light in the market.
its brightness was enhanced by about 30% than current similar products in the market. in additions, it has strong resistance to heat, weather and chemical. it has 2㎛ of soluble particle size so that it can be used in various applications with ease. it can be selective in red and blue colors
depending on the final product's characteristic. it is available at mixing with synthetic resin.
main usage is forgery-proof and security.
currency paper, valuable paper and document, bank notes, passports, identity card and lottery ticket, trademark etc. |

OVI ink shows various (different) color when being seen at an angle of 45 degrees and concern with security preservation.
but it shows no effect by general visible angle of eye.
OVI manufactured by mixing and distributing optical variable pigment with resistance under heat and light using synthetic resin.
OVI pigment is manufactured by pulverizing after classified by particle size that be separated from plastics many layer of thin film.
many layer of thin film is made by many layer on plastic substrate in turn as follow.
absorbing articles / circulation articles / reflecting articles / circulation articles / absorbing articles with vacuum metalization, electronic beam or sputtering absorbing articles(exam. chrome), circulation articles (exam. fluorinated Mg) and reflecting articles(exam. aluminum).
