Prelog became known for a self-developed design technique, the so-called "prelography". Prelography is a duplication technique that can be used primarily in the printing sector. With the help of perforated stencils, over which rigid acrylic paint is drawn with long spatulas, a haptic, scale-like pattern is created. The prelography can be combined well with other printing techniques, such as lithography, offset, etching, chine collé, wood-linocut, screen printing (also a stencil technique).
