Abstract
A steel support for a planographic plate comprises a steel plate and aluminized layers thereon, each consisting of an alloy layer in contact with said plate and an aluminum layer applied over said alloy layer. The alloy layer is 0.2 to 5 microns in a thickness, and the aluminum layer is more than 7 microns in a thickness. The aluminized plate is then cold-rolled at a rolling reduction of 30 to 85% in total to remove spangle dents or pin holes therefrom.
