Claim:
A system of embossed decorative boards, each board being rectangular in shape, each board having a first and a second opposite short edge with a third and a fourth adjacent long edge, which third and fourth edges are opposite each other, which board includes an upper side decorative surface comprising embossing on its upper side; wherein the embossing is comprised by surface structure areas of which at least four are first, second, third and fourth outermost surface structure areas on each decorative board, the first outermost surface structure areas each having one end edge coinciding with the first edge of the board, being arranged opposite to the second outermost surface structure areas having each one end edge coinciding with the second edge of the board, the third outermost surface structure areas have each one end edge coinciding with the third edge of the board and the fourth outermost surface structure areas having each one end edge coinciding with the fourth edge of the board, that at least two surface structures having different textures are present on each of the third and fourth long edges, each texture providing a second visual characteristic; wherein two adjacent outermost surface structure areas within the same board have different surface structures, such that the different surface structures can be arranged into surface structure groups according to characteristics of the surface structures, whereby the first outermost surface structure areas of the first edge are numbered in a subsequent order starting from the third edge and that the second outermost surface structure areas of the second edge is numbered in a subsequent order starting from the third edge whereby the end edge of the outermost surface structure areas with the same ordinal number of the first edge in combination with the second edge has mainly the same length and furthermore the outermost surface structure area with the same ordinal number of the first edge and the second edge has a similar surface structure, and at least some of the third outermost surface structure areas of the third edge of the board have the same texture and second visual characteristics as at least some of the fourth outermost surface structure areas of the fourth edge of the board, whereby when two boards are assembled along their long edges the surface structure areas having the same texture and second visual characteristics overlaps each adjoining edge of the adjoining boards.
