| abstract | A method of producing markings on a web (WEB1) comprises: - forming a first base portion (DOT0) in a primary web (WEB0) by locally altering at least one optical property of the primary web (WEB0) with a first laser beam (LB1), and - forming a covered web (WEB1) by covering and/or impregnating the primary web (WEB0) with an additive (AD1) after the first base portion (DOT0) has been formed, wherein the primary web (WEB0) comprises cellulose fibers, the covered web (WEB1) comprises an optically detectable first altered portion (DOT1), the first altered portion (DOT1) comprises the first base portion (DOT0) and an amount of additive (AD1) bound to the first base portion (DOT0), and the composition of the additive (AD1) has been selected such that exposing the covered web (WEB1) to a second laser beam (LB2) causes an optically detectable alteration of the additive (AD1) contained in the covered web (WEB1) in a situation where the intensity of the second laser beam (LB2) is equal to a minimum threshold intensity (IMIN,1) needed to cause optically detectable alteration of the primary web (WEB0) contained in the covered web (WEB1). |
