Abstract
Lithographic printing members have protective layers formulated specifically for use with single-fluid inks, and which are removed from the printing member during the preparatory procedures that precede printing. The protective layer provides protection against handling and environmental damage, and also extends plate shelf life; performs a cleaning function, entraining debris and carrying it away as the layer itself is removed; acts as a debris-management barrier if the layer immediately beneath the protective layer is ablated during the imaging process, preventing the emergence of airborne debris that might interfere with unimaged areas and/or imaging optics; and exhibits hydrophilicity, actually accelerating plate roll-up.
