Abstract

LOS MOTIVOS (4) ESTIMADOS DESEABLES SE IMPRIMEN EN UN PRIMER PASO EN UNA DE LAS SUPERFICIES DE UNA HOJA DE PAPEL (2) POR UN SISTEMA CONVENCIONAL. POSTERIORMENTE, EN UN SEGUNDO PASO, SE APLICA LA SUPERFICIE IMPRESA UNA RESINA, LACA TERMOPLASTICA Y OTRO MATERIAL TRANSPARENTE (6), TRAS LO CUAL, EN UN TERCER PASO, AL MENOS UN AREA DE LA SUPERFICIE ASI TRATADA SE GRABA POR PRESION Y CALOR PARA PRODUCIR DICHOS EFECTOS. FINALMENTE LA HOJA CONTINUA (2) SE CORTA EN UNIDADES (9). LA RESINA (6'') ES POLIMERIZABLE CON RAYOS ULTRAVIOLETAS Y SE POLIMERIZA AL MISMO TIEMPO QUE SE EFECTUA EL GRABADO.
