Abstract
There are disclosed a support for a planographic printing plate, which decreases dispersion in a material quality of an aluminum alloy support and improves a yield of an electrolytic graining treatment and which can produce the planographic printing plate having a small heat softening property after a burning treatment and providing a low cost, and a method for producing the same. The support for the planographic printing plate is an aluminum alloy plate comprising 0<Fe.ltoreq.0.20 weight %, 0.ltoreq.Si.ltoreq.0.13 weight %, 99.7 weight %.ltoreq.Al and the balance of inevitable impurity elements, wherein a solid solution amount of Fe is 10 ppm to 800 ppm, and the support has a tensile strength of 14 kg/mm.sup.2 or more and an offset stress of 10 kg/mm.sup.2 or more when it is subjected to a heat treatment by holding at 300.degree. C. for 7 minutes.
