The apparatus comprises a tank for retaining a pool of supporting liquid, a dispensing device associated with the tank for placing pigmented material on the surface of the pool, a roller for conveying a substrate to be coated into surface contact with the pool to lift the pigmented material from the pool, and selectively operable manipulating devices arranged to provide a desired pattern on the pigmented material of the pool. Manipulating devices comprise wave-generators, undulating tank side walls, and devices for accelerating and decelerating the substrate, each providing a characteristic visual effect in the finished product.
