Abstract
Metal-based printing members suitable for transfer-type imaging include a metal substrate and a hydrophilic, polymeric coating thereover. Desirably, the polymeric coating is crosslinked and withstands repeated application of fountain solution during printing. The polymeric coating can, however, undergo degradation where exposed to fountain solution so long as the ink-receptive portions—the areas where oleophilic material has been transferred onto the hydrophilic coating—remain intact.
