Abstract

MáSCARA DE FLUORESCêNCIA DE SUBSTRATO PARA EMBUTIR INFORMAçãO EM DOCUMENTOS IMPRESSOS. As instruções como proporcionadas neste documento se relacionam com uma marca d<39>água embutida em uma imagem a qual possui a propriedade de ser relativamente indecifrável sob luz normal, e ainda decifrável sob luz UV. Esta marca fluorescente compreende um substrato contendo agentes ópticos de intensificação de brilho e uma primeira mistura de pigmentos impressa como uma imagem sobre o substrato. A camada de mistura de pigmentos possui como características uma propriedade de fortemente suprimir a fluorescência do substrato, bem como uma propriedade de baixo contraste sob iluminação normal em relação ao substrato ou a uma segunda mistura de pigmentos impressa em proximidade espacial próxima à primeira mistura de pigmentos, de modo que o substrato sintetizado com a imagem resultante adequadamente exposto a uma fonte de luz ultravioleta irá produzir uma imagem discernível evidente como uma marca fluorescente.
