A gold/silver cubical label printing method using sol is provided to reduce the manufacturing cost by printing patterns on labels by using the sol instead of the expensive silicon. The gold/silver cubical label printing method using sol comprises the steps of: forming patterns on a film of an engraving plate; producing print ink by mixing the sol and a plasticizer; putting the print ink into the engraving plate formed with the patterns and putting a label sheet(1) into the bottom side; printing the patterns formed on the film of the engraving plate, on the upper surface of the label sheet by penetrating the print ink through the upside of the inserted label sheet; hardening the print ink of the printed label sheet by heating the ink at the temperature of 150-200 deg.C; and instantly bonding gold or silver foils(2) on the upper side of the label sheet by bringing the gold or silver foil into contact with the label sheet at the temperature of 150-200 deg.C while moving the label sheet with the hardened print ink in one direction and passing the gold or silver foil across the label sheet on the label sheet.
