    Abstract: A method for producing markings (MRK1 ) on a moving web (WEB1 ) comprises: - moving the web (WEB1 ) in a longitudinal direction (SX), - delivering laser light (LB2) to a moving aiming point (SP2) by using a first beam steering body (100) and a second beam steering body (200) such that the position (x(t),y(t)) of the aiming point (SP2) depends on the angular orientation (a) of the first body (100) and on the angular orientation (β) of the second body (200), - rotating the second body (200) from a first angular orientation (β1 ) to a second angular orientation (β2), the rotation from the first angular orientation (β1 ) to the second angular orientation (β2) defining a writing period (TA), wherein the rotation of the second body (200) during the writing period (TA) moves the aiming point (SP2) such that the average longitudinal velocity component (vx2) of the aiming point (SP2) is in the range of 50 to 150% of the velocity (v^ of the web (WEB1 ), - rotating the first body (100) such that the aiming point (SP2) crosses a longitudinal reference line (YREF) a plurality of times during the writing period (TA), and - controlling the intensity of the laser light (LB2) according to the angular orientation (a) of the first body (100) and according to the orientation (β) of the second body (200).

    Abstract: The invention relates to safety paper provided with an authentication for authenticating the paper. In the safety paper according to the invention, the base paper is provided with a structural deviation comprising at least one or some of the following: one or more perforations holes thinner/thicker spots/areas thinner/sparser spots or areas, or colouring agent layers applied onto the base paper. Furthermore, the structural deviation is covered with a coating material layer. The coating material layer covers at least one side of the base paper substantially entirely in such a way that the overall thickness of the paper is primarily constant over the whole area of the paper. However, the coating material of layer has a different thickness at the structural deviations with respect to the other areas of the paper. The invention also relates to a method for manufacturing the safety paper according to the invention.
