Abstract

A printing form and process relating to the formation of images on the printing form. The printing form includes a ferroelectric layer (1) on which photoferroelectric effect is used to polarize or depolarize the layer to form the image to be printed in the layer (1). The printing form may also include a layer which is neither ferroelectric nor has the function of a photoconductor which adjoins the ferroelectric layer 1. In this instance, the photoelectric effect is used to form the image to be printed on the ferroelectric layer.
