Abstract
Procedimiento para la obtención de moldes de imprenta reticulados, con retículos de cualquier clase de ángulo de retículo deseado y cualquier amplitud de retículo por tanteo de muestra por líneas opto-electrónico para la obtención de una señal de imagen y por registro por líneas mediante un órgano registrador, movido relativamente por encima de un medio de registro, en que está coordinado al medio de registro un sistema de coordenadas ortogonal subdividido en elementos de superficie y orientado en dirección de línea, en que se obtienen continuamente las coordenadas locales de los elementos de superficie recorridos momentáneamente por el órgano registrador y en que continuamente por comparación de la señal de la imagen con una señal de umbral de retículo se genera una señal de registro para el órgano registrador, en que la señal de registro dirige el registro de los distintos puntos de retículo como configuración de elementos de superficie en el sistema de coordenadas.
