Abstract
The present invention relates to a method for production of a three-dimensional dyed macropattern in a web of web-shaped flexible material. The method comprises a bonding device being made, in interaction with the dye-coated tops of the raised macroportions, to form bonding points and three-dimensional bonding areas at the same time as the bonding areas and/or the bonding points are dyed, thereby forming a three-dimensional dyed macropattern.
