ABSTRACT:
The water-loving properties of an anodized aluminum lithographic surface are enhanced or restored by treatment with a solution containing a monomeric, organo-phosphonic acid chelating compound or salt thereof. Such treatment can take place following, during or in lieu of the treatment of anodized aluminum in web form with an alkali metal silicate in the process of manufacturing printing plates. Alternatively, the treatment can be carried out as a plate is developed and/or prepared for the press. In a third approach, an organo-phosphonic acid chelating compound can be incorporated into a fountain solution, ink or correction fluid.
