embodiments of the present invention involve printing members that avoid ablation imaging mechanisms and , as a result , crosslinked topmost layers . topmost layers as described herein exhibit good thermal stability and durability during printing , but can be cleaned with water or aqueous cleaning fluids following imaging . it is found , in some embodiments , that the viability of certain topmost layers can be critically dependent on the nature of the underlying substrate , e . g ., in terms of texture and / or surface volume .
