A method for manufacturing a gravure transfer-coated continuous metal plate, wound in the form of a coil, comprising: coating, over the metal plate, a primer coating material; curing the primer coating material to form a lower coating layer; thermally transferring a desired pattern from a gravure transfer sheet onto the lower coating layer, thereby forming a transfer coating; coating, over the transfer coating, an upper coating material of thermosetting fluorine resin, thermosetting polyester resin, or UV-thermosetting polyurethane-acryl-based resin; and curing the upper coating material to form an upper coating layer. The primer coating material consists essentially of: 20-40% polyester resin having a number average molecular weight of 5,000-20,000 and a glass transition temperature of 10-50° C., 4-15% melamine resin, 1-10% urethane resin, 0.3-3% isocyanate, 15-35% pigment 30-50% hydrocarbon/ester-based mixed solvent, and 1.5-3% additives.
