A phase hologram is embossed in a mylar web having a reflective layer which is made from tin tungsten oxide, zinc sulfide, or a mixture thereof. The embossed microtexture produces a hologram that is semi-transparent, thereby allowing the visualization of indicia underlying the hologram.

Un hologram de la fase se realza en una tela de mylar que tiene una capa reflexiva que se haga del óxido del tungsteno de la lata, del sulfuro del cinc, o de una mezcla de eso. El microtexture realzado produce un hologram que sea semi-transparente, de tal modo no prohibiendo a la visualización del indicia subyacente el hologram.
