摘要： A roll for metal rolling has a roughened surface formed by an electrolytic treatment in an electrolytic solution while using the roll as an anode. When the roll is used to emboss an aluminum plate, it is possible to obtain an aluminum plate with an uneven structure having regulated positions of levels of peaks and a larger number of the peaks. A presensitized plate formed by use of the aluminum plate as a support has excellent printing performances particularly in the number of printed sheets and sensitivity.
