Abstract
Se describe un método para el cálculo de la resolución de tramado mediante dithering o diffusion de imágenes destinadas a la insolación de pantallas de serigrafía que permite maximizar la eficacia en la insolación de la pantalla, evitando la aparición de Muaré, reduciendo al mínimo el porcentaje de pérdida de punto, permitiendo controlar el tamaño mínimo de punto impreso y maximizando el número de niveles de gris imprimibles.
