Abstract

Flexographic printing plates are produced by means of direct laser engraving by a process in which the starting material used is a flexographic printing element which has a relief-forming layer comprising a combination of a styrene/butadiene block copolymer and 20-40% by weight of a plasticizer. Flexographic printing plates obtainable by this process are used for flexographic printing with water-based or alcohol-based printing inks.
