Flexographic printing plate precursor, imaging assembly, and use

A flexographic printing plate imaging assembly comprising:

• a) an imaged film comprising a mask image, and
• b) in optical contact with the imaged film, a flexographic printing plate precursor that can be imaged and developed to provide a flexographic relief image, the flexographic printing plate precursor comprising:
• a radiation curable layer in which a flexographic relief image can be formed, and
• a transparent release layer disposed over the radiation sensitive layer, the release layer consisting essentially of a miscible mixture of a polyamide in an amount of at least 20 weight % and up to and including 80 weight % and a natural or synthetic rubber latex in an amount of at least 20 weight % and up to and including 80 weight %, both based on the transparent release layer dry weight, and
• the transparent release layer has a peel force in relation to the imaged film comprising a mask image of at least 50 g/inch and up to and including 200 g/inch (at least 127 g/cm and up to and including 508 g/cm).
