A process for preparing a photohardenable elastomeric element having increased exposure latitude, said element having a support and a photohardenable layer wherein at least (a) a thermoplastic-elastomeric polymeric binder comprising a copolymer of isoprene, (b) a liquid plasticizer, and (c) a petroleum wax, are premixed is described.

Process for preparing photohardenable elastomeric element having

A process for recycling exposed and/or unexposed photopolymer flexographic printing plate containing a photopolymerizable recording layer and a support, said process comprising (a) separating the recording layer from the support and comminuting the material and (b) adding the material to a photopolymer mixture is described. The process reduces waste problems, is more environmentally friendly and is used to prepare photopolymerizable flexographic printing plates containing less raw materials.
