Abstract

"QUADRO PARA ESCREVER TENDO LINHAS DE REFERêNCIA INVISìVEIS à DISTâNCIA E PROCESSO PARA PRODUZì-LO". A presente invenção está relacionada a um quandro para escrever tendo linhas de referência invisíveis a uma distância e um processo para produzir o mesmo. O quadro compreende pelo menos um substrato suporte e um substrato para escrever grudados juntos, onde as linhas de referências são impressas de tal modo que elas se mantêm presas entre o substrato suporte e o substrato para escrever, aumentando sua durabilidade. As linhas de referência podem ser notadas claramente por uma pessoa próxima do quadro para escrever, no instante em que elas são invisíveis para uma pessoa afastada do citado quadro.
