Attachment means for attaching a flexographic printing form, particularly a printing form of photopolymeric material, on a plate cylinder, is provided with a flexible supporting layer and a photopolymeric layer supported by the supporting layer being fully exposed. In order to obtain a particularly effective attachment means the adherent characteristics of a photopolymeric layer are advantageously utilized. Experiments have shown that these adherent characteristics are also maintained in case of intensive use during at least 8 to 12 months. Moreover, on the one hand a good attachment of the printing form on the plate cylinder is achieved, whereas on the other hand the printing form can relatively easily be removed from the adherent photopolymeric layer and no residual photopolymeric material remains on the printing form. In this way a long lifetime of the attachment means applied on the plate cylinder is achieved, while on the other hand the printing form needs no longer undergo any cleansing treatment. Damaging of the printing form by removal is excluded as well so that the printing form is more times available for repeat order without any problem.
