Abstract

See full text

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 (and thereby removed from unimaged areas) 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.
