Abstract: The present invention relates to a method for making a fibre-based substrate such as paper of board, which as filler particles or as a coating colour pigment constituent comprises calcium sulfate dihydrate pigment. According to the method, the calcium sulfate dihydrate pigment is introduced into the papermaking/coating process as a calcium sulfate dihydrate pigment slurry for the formation of the paper web and/or its coating formulation. In order to avoid losses due to dissolution of the pigment, it is proposed for the preparation of said calcium sulfate dihydrate pigment slurry to use a powdery calcium sulfate dihydrate pigment or a calcium sulfate dihydrate pigment starting slurry and to dilute it with water which is essentially presaturated in calcium sulfate dihydrate.
