Abstract (en)

[origin: WO9319939A2] The present invention relates to a method and apparatus for printing in which the fountain solution for a lithographic printing device is treated by the direct injection of electromagnetic radiation. Most preferably, the electromagnetic radiation is within the radio frequency range and is injected through a conductor directly in contact with the fountain solution. Such treatment eliminates or substantially reduces the need for chemical treatment of the fountain solution, especially the need for isopropyl alcohol or alcohol substitutes.
