The present invention relates to a method of and an apparatus for making a patterned board product. A wet fibrous web (w) is supplied directly from a forming section of a boardmaking machine to an imprinting press nip (12) having at least one roll (8) with a surface that has raised (8E) and/or recessed (8B, 8C) portions to form a patterned surface (8A) on the roll. A heater (58) is provided for heating at least the patterned surface (8A) of the roll (8). The wet web (w) is dewatered in the press nip (12) during the pressing of the heated patterned surface (8A) of the roll (8) into the web (w) to form to form a reverse image of the pattern therein. The web (w) is dried to a desired dryness, while the heated patterned surface (8A) of the roll (8) is maintained in contact with the imprinted pattern (2B, 2E) in the web (w), so as to achieve a patterned stiff board product, which may have one imprinted side and one plain side. In a subsequent bonding section, a facing (4) or another imprinted web (2') may be bonded to the produced imprinted web (2).
