Abstract
A flexographic printing precursor includes a support and a photopolymerisable layer including a monomer, an initiator and having a thickness between 0.5 mm and 7.0 mm, characterized in that the photopolymerisable layer contains magnetic or magnetisable particles. A method of developing the flexographic printing precursor to obtain a printing element with a relief image using a magnetic field is provided.
Claims6
A method of making a flexographic printing element, the method comprising the steps of:
- a) providing a flexographic printing precursor including:
- a support;
- and
- a photopolymerizable layer including a monomer, an initiator, and magnetic or magnetizable particles, the photopolymerizable layer having a thickness between 0.5 mm and 7.0 mm;
- b) image wise exposing the flexographic printing precursor to obtain exposed and non-exposed areas in the photopolymerizable layer;
- and
- c) bringing the photopolymerizable layer into a magnetic field having a magnitude and direction to at least partially remove the photopolymerizable layer in the non-exposed areas of the photopolymerizable layer.
