Abstract:
A sublimation process of transferring a decal to the surface of a watch case, said process comprising the steps of:(a) providing the surface of the watch case with a coating; (b) preparing a decal-bearing paper corresponding in size to the coated surface of the watch case and preparing an airtight soft bag of a plastic material and having an opening; (c) drying the coating of the surface of the watch case before the watch case and the decal-bearing paper are put into the bag such that the coating is in contact with the decal of the decal-bearing paper; (d) arranging the bag containing the watch case and the decal-bearing paper in an airtight space of a vacuum device by which the bag is exhausted of air to cause the bag to collapse completely before the opening of the bag is sealed off such that the bag becomes airtight; (e) baking the airtight bag of the step (d) to bring about the sublimation transfer of the decal to the watch case from the decal-bearing paper; and (f) removing the watch case from the airtight bag upon completion of the process of cooling the watch case.
