Abstract: A topographical imaging device is placable after a creping process which causes folds to the tissue sheet and the topographical imaging device provides image data having three-dimensional information on the tissue sheet. A data processing device determines, on the basis of a shape of a cross section of at least one fold of creping of the tissue sheet, at least one of the following: thickness of the tissue sheet, softness of the tissue sheet.
