Each relief was then stained in carefully calculated solutions of yellow, cyan and pink dyes. The coloured reliefs would then be rolled individually onto a separate substrate in perfect registration to create an image. But because the dyes tended to wander, developers seldom printed the images onto paper. Instead, they chose to create transparencies by overlaying the matrices and placing them between glass.
