Abstract
A process for producing a surface covering with an embossed printed surface is described. A substrate (16) is continuously moved through a production line, and this substrate (16) is first provided, in a printing equipment (12), with a printed pattern and thereafter, in an embossing equipment (14), with an embossed pattern, which is registered with the printed pattern. The printing equipment (12) produces the printed pattern in-line with the production of the embossed pattern. During printing in the printing equipment (12), the printed pattern is stretched or compressed, dynamically responsive to indicators of misalignments between the printed pattern and the embossed pattern, so as to correct or prevent the misalignments. A production line for carrying out this process is also proposed.
