摘要： The invention relates to a method of manufacturing an impregnate (8) that is provided with markings (7), a wood or fibre board coated with the impregnate, a high-pressure laminate that contains the impregnate and a concrete casting mould that is coated with the impregnate. According to the invention, markings (7) are produced on a moving fibrous material web (1) by a laser printing head (2), after which resin (3) is impregnated into the marked web and the impregnate is dried. The marking, impregnation and drying stages can be carried out as a continuous process without interrupting the movement of the web. The markings (7) can form, on the web, a pattern which is formed by a logo or other similar figure or text and which is constantly repeated, and they can be distinguished from the web as darker or lighter than their surroundings, or by their shades or opacity.
