Abstract
A process for the manufacture of transparencies, characterized in that, prior to the cutting of cellulose acetate sheets, it is subjected to a de-electrification process, after which it is printed by any type of printing machine, with inks that are not opaque to the projection which, once dry, allow the aforementioned cellulose acetate plates to be plasticized, with lacquer to the polyelum, and once this plasticizing operation is completed, the cutting is carried out, adaptable to the planned projection machine.
