Method and apparatus for decorating objects by means of sublimatic inks
A method for decorating objects by means of sublimatic inks, which provides for the steps that consist in providing a shrink-wrap sheet-like element to which at least one layer of sublimatic inks is applied and joining two opposite ends of the sheet-like element in order to obtain a sleeve with the face of the sheet-like element directed toward the inside of the sleeve, inserting axially in the sleeve at least one object to be decorated, applying heat in order to obtain an at least partial shrink-wrapping of the sleeve, creating a difference in pressure between the internal side and the external side of the sleeve in order to establish a lower hydrostatic pressure on the inner side of the sleeve than on its outer side, and applying heat in order to cause the sublimation of the sublimatic inks.
