Abstract
Procedimiento para la preparación de clichés de autotipia para la impresión en uno o multicolor mediante retícula o enrejado de abertura variable caracterizadas por el hecho de que las dos retículas móviles utilizadas tanto si sus cuadrículas son idénticas como si son solo semejantes se monten en sendos marcos enlazados entre sí por unos ejes o vástagos excéntricos guiados por ranuras previstas en uno y otra dispuestas entre sí ortogonalmente para conseguir siempre que todos los vértices de las mallas de una de dichas retículas describan a la vez respecto a los de las mallas de la otro el perímetro de un cuadrado o de un paralelogramo con lo que los colores o mejor dicho las aberturas útiles de la retícula compuesta resultante no se superpongan nunca ni pierdan jamás el paralelismo de sus lados y si solo aumenten o disminuyan en su tamaño; o sea que los efectos de interposición y gradación de colores se consigan ópticamente sin superposición física de los colores y sin los riesgos de los efectos de moaré por interferencias angulares tan frecuentes cuando las retículas giran circularmente una sobre otra.Procedure for the preparation of autotype clichés for printing in one or multi-color by means of a grid or grating of variable aperture characterized by the fact that the two mobile grids used, whether their grids are identical or if they are only similar, are mounted in two linked frames. between each other by eccentric shafts or rods guided by grooves provided in one and the other arranged orthogonally to each other to always achieve that all the vertices of the meshes of one of said grids describe the perimeter with respect to those of the meshes of the other of a square or of a parallelogram with which the colors or rather the useful openings of the resulting composite lattice never overlap or never lose the parallelism of their sides and if they only increase or decrease in size; In other words, the effects of interposition and gradation of colors are achieved optically without physical superposition of the colors and without the risks of the moiré effects due to angular interferences so frequent when the grids rotate circularly over each other.
