A spray nozzle system is useful for applying imageable materials onto substrates. The system may be used for on-site fabrication of lithographic printing surfaces for use in printing. A wash nozzle and vacuum port are integrated with the spray nozzle for use in cleaning the printing residues from a used printing surface in preparation for a subsequent print job. The integrated nozzle assembly is useful in coating and cleaning operations, performed either on-press or off-press, and enables the reuse of a single printing substrate in a number of print jobs.
