In the case of nitrofrottage , templates are transferred to an image base with the help of a suitable solvent . The original is "rubbed" into the picture ground with a solvent-based cloth.

Templates can be images or texts from magazines, newspapers, prints, etc., the color of which can be removed and transferred by the solvent used ( nitro thinner ). As a result of this process, the transmitted image loses its sharpness and becomes a diffuse image whose appearance can never be precisely predicted.

Because of the poor lightfastness of the printing inks used for magazines, nitrofrottages are not suitable for permanent works of art. They tend to fade, especially in the red area. Nitro frottage , however, is suitable for copying templates onto the image carrier and then reworking them with lightfast colors.

In addition to canvas , paper and textiles , materials with a smooth, absorbent surface, such as plaster of paris, are suitable as a background .

In the fine arts , the nitrofrottage contains elements of both frottage and monotype .
