Abstract

Es wird ein Verfahren zur Erzeugung einer Struktur aus hydrophilen (34) und hydrophoben Bereichen (32) auf einer Druckform (30) vorgestellt, welche in einem ersten, im wesentlichen unstrukturierten Zustand ein Polymermaterial mit Imid-Gruppen, beispielsweise Polybenzoldiimid oder Polyamidimid, aufweist. Das Verfahren umfasst eine sich an eine örtlich selektive Belichtung durch UV-Licht zeitlich nachgehende chemische Behandlung der Oberfläche mit einem Oxidationsmittel. Optional kann der örtlich selektiven Belichtung eine großflächige chemische Behandlung der Oberfläche mit einer starken Base vorausgehen. Durch eine großflächige chemische Behandlung der Oberfläche mit einer starken Säure kann die Druckform (30) wieder in den ersten Zustand überführt werden. Die strukturierte Druckform (30) eignet sich für den Einsatz im Offsetdruck.

A method for producing a structure from hydrophilic (34) and hydrophobic areas (32) on a printing form (30) is presented which, in a first, essentially unstructured state, has a polymer material with imide groups, for example polybenzene diimide or polyamideimide. The method comprises a chemical treatment of the surface with an oxidizing agent, which is temporally subsequent to a locally selective exposure to UV light. Optionally, the locally selective exposure can be preceded by a large-area chemical treatment of the surface with a strong base. A large-area chemical treatment of the surface with a strong acid enables the printing form (30) to be returned to the first state. The structured printing form (30) is suitable for use in offset printing.
