摘要:
Pre-coated metal sheet for use in the manufacture of bakeware and other products intended to be used at high temperatures is first given a coating, on one or both sides, of a material, e.g. a lacquer, polyethylene sulphonate or a non-stick material, capable of withstanding temperatures of at least 250°C, baked at 350-450°C to dry the coating, and then has a printing medium compatible with the coating material applied to, and cured on, the coating as decoration. The sheet may be coiled between the coating and decoration steps, and may be coiled again after the decoration has been cured. Preferably the coating is applied by the reverse roll method and the decoration is printed on the coating by the forward roll method.
