Abstract (en)
[origin: US4840713A] A process is disclosed for the electrochemical roughening of aluminum for use in printing plate supports, which is carried out by means of an electrolyte containing sulfate ions and aluminum chloride; preference is given to sulfuric acid and aluminum chloride. Printing plate supports roughened by the process according to the present invention show a particularly uniform, pit-free and overall roughening structure.
