A multiple-layer flat structure in the form of a printing blanket or a printing plate for flexographic and letterpress printing with laser engraving

The invention relates to a multiple-layer flat structure (1) in the form of a printing blanket or a printing plate for flexographic and letterpress printing with: - a printing layer (2) which is made from a polymeric material and is provided with laser engraving; - at least one compressible layer (3), and - at least one strength-support layer (4); wherein the individual layers form an adhesive connection among one another. The multiple-layer flat structure (1) according to the invention is distinguished by the fact that the polymeric material of the printing layer (2) is a vulcanisate. Advantageous materials are proposed in this regard. The printing layer (2) expediently lies directly on a compressible layer (3). The compressible layer (3) is in turn in direct contact with a strength-support layer (4).
