Vivid holographic images and text can now be produced by means of an ordinary inkjet printer. This new method, developed by a team of scientists from ITMO University in Saint Petersburg, is expected to significantly reduce the cost and time needed to create the so-called rainbow holograms commonly used for security purposes to protect valuable items such as credit cards and paper currency from piracy and falsification. The results of the study were published 17 November in the scientific journal Advanced Functional Materials.
