Abstract
A panel, in particular floor panel, having a support board made of glued and compressed fiber material to which a termination layer is applied in each case on a top side and an underside, and the termination layer of the top side has a structured surface, and to a process for producing such a panel or such a support board. The object of the invention is to provide a panel or a support board comprising binders and fillers and also a process for producing the same, by means of which surface-structured panels can be produced more quickly and cost-effectively. This object is achieved in that the density on the top side of the support board is lower than the density of the support board on the underside.
