Process for producing a surface covering with an embossed printed surface

A production line for producing a heterogeneous resilient floor or wall covering with an embossed surface, said production line comprising:

• one or more carrier belts for moving a substrate through said production line
• a digital printer for applying a printed pattern onto said substrate as said substrate is moved;
• an embossing equipment downstream of said digital printer, for providing said substrate with an embossed pattern, which is registered with said printed pattern;
• and
• one or more optical sensors for determining real-time indicators of misalignments between said printed pattern and said embossed pattern;
• wherein the substrate remains continuous at least up to the embossing equipment;
• and
• wherein the production line includes a controller operatively connected to said optical sensors for receiving said real-time indicators of misalignments, said controller configured to act, dynamically in response to said real-time indicators of misalignments, upon said one or more carrier belts and/or said digital printer in such a way that said printed pattern is stretched or compressed and said misalignments between said printed pattern and said embossed pattern are corrected or prevented.
