In order to implement the process, the starting point is a transparent or coloured support on which is deposited, firstly, a special ink, and then the colours which are desired on said ink are printed, the next step being the deposition of a photoemulsion of the type generally used in the graphic arts, the whole next being subjected to a system of insolation, taking, as negative, a stencil plate of dots or any other whimsical small figures. Next, the photoemulsion is developed using water and then the ink is developed with alcohol until everything that is not protected by the photoemulsion is removed, thereby obtaining a light-polarising screen which is able to support publicity on one or both faces. <IMAGE>
