Abstract (en)
[origin: EP0613786A1] Starting with the classic incorporation to the security paper of security threads or strips (1) carrying a drawing (2) or any mark that can be readily detected with the naked eye, obtained upon a metallised background (3), the process comprises rendering the said metallised background (3) discontinuous, to define a sort of screen or the like, that reduces the intensity of the background and renders the latter more difficult to reproduce by optical means and at the same time allowing the said drawing (2) to be printed using cheaper and more accessible techniques. Furthermore, the discontinuous character of the metallised background (3) allows fluorescences to be used on either the screen dots (3) upon non-fluorescent background material or upon fluorescent background material having a colour that differs from that of the screen fluorescence. <IMAGE>
