METHOD FOR PROVIDING DIRECTLY ON A GRAPHIC PRINTING LINE A UNIQUE COLOURED SIGN WITH REFLECTING DOTS, HAVING AN ALPHANUMERIC CODE INSCRIBED AT THE CENTRE, FOR FILING AND READING THE ORIGINAL AND COMPARING IT WITH A FAKE

摘要

The purpose of the present invention is to propose a method in which encapsulated micro-drops of colour are electrostatically attracted and squeezed not with a roller and counter-roller but with laser-beam barriers. With this new system a new unique sign is obtained that is simpler to read and file and easier to re-read remotely with any mobile-phone apparatus or a purposely provided portable apparatus, and then compare with the one previously filed. To sum up, the three innovations that are described in this new invention are a new pattern of the unique sign obtained with micro-encapsulation of chromatic colours, blind colours/inks or ones variable on the basis of the various ranges of wavelength and frequency of exposure, magnetic colours, and glitters, the distribution of the micro-drops of colour (25, 26, 27, 28) and of the encapsulated glitters (29, 30) obtained electrostatically, and squeezing and anchorage thereof on paper using a laser barrier.
