Sigma Prefilled Colour Ribbon Cassette with YMCKT colour panel ribbon. Entrust YMCKT ribbons are used for printing a combination of full-colour images and one-color text or barcodes, and feature an Earth-friendly biodegradable core. YMCKT ribbons consist of yellow (Y), magenta (M) and cyan (C) panels for printing a full spectrum of colours by combining the colours using varying degrees of heat. The K panel is a black resin panel, typically used for printing text and barcodes and the T panel is a thin, clear protective overlay. Prefilled ribbon cassettes make switching ribbons easy.
