System and method for printing on a treated surface

A method for safely differentiating a three dimensional object subsequent to its creation and varnish protection by means of applying and sealing a decoration and/or data between the original and a final varnish layers. The three dimensional object may be decorated and/or contain data from its original manufacturing process but it may also be protected by a varnish prior to utilizing this process. The method enables the addition of decoration and data at any time or location subsequent to the original manufacturing process. The process takes place on top of the original varnish and may be subsequently sealed by applying another varnish layer.
