Fotospeed RT20 Copper/Red Toner is a liquid toner which is supplied in a two part concentrate that makes a single working solution. It is specifically designed for the toning of Fiber and Resin Coated B&W papers. The shade of the Copper/Red tone is adjusted by the length of time the print is allowed to stay in the working solution. The longer it remains in the solution the more toned it becomes.
