摘要： A process for roughening aluminum or alloys thereof for printing plate supports, wherein an electrochemical roughening is performed by means of alternating current in an acidic electrolyte including sulfate ions and chloride ions, the chloride ions being in the form of aluminum chloride. In a preceding or subsequent rougheniong stage, mechanical roughening and/or electrochemical roughening by means of alternating current in an electrolyte is carried out. The electrolyte can include hydrochloric acid and aluminum ions, nitric acid and aluminum ions or sulfuric acid and chloride ions.

摘要： A process for roughening aluminum or aluminum alloys useful as support material for printing plates, in which process two electrochemical roughening steps are carried out in direct succession and are followed by a pickling step. Printing plates are produced from this support material by coating with light-sensitive coatings, which printing plates, when exposed and developed, give corresponding printing formes of very uniform topography, high run stability and good damping agent supply.
