ABSTRACT:
A printing aluminum alloy material plate is described which provides good printing characteristics, that is, surface-treatment ability, burning ability and ink stain resistivity; the plate is obtained from an aluminum alloy material which is cold-rolled at a reduction rate of from 20 to 95% after being subjected to intermediate annealing at a temperature of 300.degree. to 550.degree. C. wherein the aluminum alloy material comprises 0.25 wt % or less Si, from 0.05 to 1.0 wt % Fe, 0.03 wt % or less Cu, 0.10 wt % or less Ti, and 0.03 wt % or less Mg and the balance of unavoidable impurities and Al.
