Abstract

MáSCARA PADRãO DE FLUORESCêNCIA DE SUBSTRATO PARA INCORPORAR INFORMAçãO EM DOCUMENTOS IMPRESSOS. A presente invenção refere-se a ensinamentos conforme aqui proporcionados que referem-se a uma marca d'água incorporada em uma imagem que tem a propriedade de ser relativamente indecifrável sob luz normal e contudo decifrável sob luz UV. Essa marca fluorescente compreende um substrato contendo agentes óticos de aumento do brilho e um primeiro padrão de mistura de corantes impresso como uma imagem no substrato. A camada de padrão de mistura de corantes tem como características uma propriedade de supressão, fortemente, de fluorescência de substrato, bem como uma propriedade de baixo contraste sob iluminação normal contra o substrato ou um segundo padrão de mistura de corantes espacial impresso em proximidade espacial com o primeiro padrão de mistura de corantes. O segundo padrão de mistura de corantes espacial tendo uma propriedade de fornecimento de um nível diferente de supressão de fluorescência de substrato do primeiro, de modo que o substrato renderizado de imagem resultante adequadamente exposto a uma fonte de luz ultravioleta, produzirá uma imagem discernível evidente como uma marca fluorescente.
