A process of producing a coloured hologram is provided. The process comprises preparing a lacquer composition comprising a UV/EB-hardening acrylic resin and at least one pigment, said resin providing instant hardening upon irradiation; applying said lacquer composition to selected areas of a flexible support by means of a rotary printing machine; shaping the applied lacquer to impart in it a relief that forms a hologram; and irradiating said shaped areas with a UV light/EB radiation.
