Abstract
The invention relates to a method of forming of a patterned photopolymer coating on a printing roller in which a photopolymer coating, present on said roller, and covered by a light-sensitive intermediate layer is exposed in a first stage to form an image of opaque and translucent parts in said intermediate layer. Subsequently the photopolymer layer is exposed via the image formed in the intermediate layer, after which the photopolymer layer is developed. Between abovementioned exposures, in case of a relatively thick, flexible, photopolymer, a period is waited to ensure that depressed parts of the photopolymer layer have returned to their original state. The invention also relates to a printing roller thus obtained.
