due to the continuous reduction of color image processing and printing costs, the image quality has made long progress, and the production efficiency will increase by more than 15%, At present, crimes of counterfeiting currency and securities using color printers occur from time to time
in response to this situation, Japan adopted a variety of anti-counterfeiting technologies for the newly issued 2000 yen banknotes during the Okinawa summit in July 2000. In short, it includes: watermark, discolorable optical ink, pearl ink, micro anti-counterfeiting text, deep intaglio printing, identification mark, special distribution ink, etc
as one of the main hard currencies in the world, the euro is not only printed from inking and gravure. Due to the problems of the food industry for many times, printing technology and joint efforts are made to prevent counterfeiting, but also the so-called OVD (optically valuable device) is used to improve the anti-counterfeiting ability of the euro
similarly, some new anti-counterfeiting measures have been added to the printing of US dollars. For example, the use of color changing optical ink Ovi (optically valiab degradable agricultural film into Xinjiang nbsp; five crops open test Le ink) and safety line, etc
there is also a new trend in the world's banknote printing technology, that is, using polymers made of plastic as raw materials to replace traditional paper to print banknotes. This practice has begun to be adopted in Australia centered countries with high temperature and humidity near the equator
