Process for manufacturing an article enabling a decorative film to be fixed to a final support

A method for manufacturing an article allowing for an in particular the application of a decorative film onto a final support, comprising the following steps:

• providing a casting support having surface characteristics such that a paint material can be applied in a form of a film directly on said casting support, while generating after drying of the paint material film, first controlled adhesion forces between the casting support and the paint material film (20),
• applying at least one layer of paint material onto the casting support to form a film, and cause this at least one layer of paint material to dry,
• applying a first extraction support onto a free surface of the paint material film, without adding an adhesive distinct from said first extraction support, with second controlled adhesion forces between the paint material film and the first extraction support, and
• exerting, between the casting support and the first extraction support, a separation effort in conditions such that the first adhesion forces are lower than the second adhesion forces, so as to peel off an assembly made of the extraction support and the paint material film,
• wherein the second adhesion forces, after peeling off, being such that the paint material film can be separated from the first extraction support.
