A method of forming a photopolymer layer on a printing substrate (e.g., flexographic printing sleeves and cylinders) is provided. The method includes providing a photopolymer composition that contains a photopolymer and at least one monomer bonded to the photopolymer. The monomer can help reduce the hardness of the resulting photopolymer composition. In addition, the method also includes spraying the photopolymer composition onto a rotating generally cylindrical surface of the printing substrate. In one embodiment, the sprayed photopolymer composition is then cured. The resulting photopolymer layer is seamless and continuous and, in some embodiments, has a hardness of between about 50 to about 70 Shore A.
