摘要：A method of producing an aluminum support for a printing plate by
electrochemical graining. The aluminum support is soaked in an acid electrolytic liquid of

An alternating current including a tFpositive period and a tR negative period is applied between the aluminum support and anopposite electrode, with current reach peak levels in the positive period tF and thenegative period tR being reached within the initial range of 0.1-20% of either period.
