| 20100307360 | METHOD FOR MAKING A LITHOGRAPHIC PRINTING PLATE PRECURSOR - A method for making a lithographic printing plate precursor comprising the steps of: (i) providing a grained and anodized aluminum support; (ii) treating the support with an aqueous solution comprising a salt of zirconium; (iii) treating the support with an aqueous solution comprising a compound comprising a phosphonic acid group and/or an ester or a salt thereof; (iv) applying a coating comprising hydrophobic particles and a binder; (v) drying said coating. | 12-09-2010 |
| 20110014381 | METHOD FOR MAKING A LITHOGRAPHIC PRINTING PLATE SUPPORT - A method for making a lithographic printing plate support includes the steps of providing an aluminum support; graining the support in a graining electrolyte solution; and treating the grained support in a desmut electrolyte solution containing hydrochloric acid by applying a direct current resulting in a charge density Q; wherein the desmut electrolyte solution has a pH less than 1 and Q is at least 400 C/dm | 01-20-2011 |
| 20110048265 | METHOD FOR MAKING A LITHOGRAPHIC PRINTING PLATE SUPPORT - A method for making a lithographic aluminum printing plate support comprising the steps of (i) graining said support by applying a charge density x; (ii) desmutting the grained support; (iii) graining the desmutted support by applying a charge density y; (iv) anodizing the support; characterized in that during each graining step a current density varying between 80 and 250 A/dm2 is applied and that the ratio x/x+y varies between 0.3 and 0.7. | 03-03-2011 |
