Embossed decorative boards

Embossed decorative boards (1) having a first and a second opposite edge (1I and 1II respectively) with a third and a fourth adjacent edge (1III and 1IV respectively), which board (1) include an upper side decorative surface (2) an upper side embossing and a base layer,

• characterised in that the embossing is comprised by surface structure areas (10) of which at least four are first and second outermost surface structure areas (10L and 10R respectively), the first outermost surface structure areas (10L) each having one end edge coinciding with the first edge (1I) of the board (1) while the second outermost surface structure areas (10R) has each one end edge coinciding with the second edge (1II), being arranged opposite to the first edge (1I), that at least two surface structures having different visual characteristics is used, wherein two adjacent outermost surface structure areas (10L and 10R respectively) within the same board (1) has different surface structures, that the different surface structures can be arranged into surface structure groups after its visual characteristics whereby the first outermost surface structure areas (10L) of the first edge (1I) is numbered LI, LII, LIII etc. in a subsequent order starting from the third edge (1III) and that the second outermost surface structure areas (10R) of the second edge (1I) is numbered RI, RII, RIII etc. in a subsequent order starting from the third edge (1III) whereby the end edge of the outermost surface structure areas (10L and 10R respectively) with the same ordinal number of the first edge (1I) and the second edge (1II) has mainly the same length while the outermost surface structure area (10L and 10R respectively) with the same ordinal number of the first edge (1I) and the second edge (1II) has a similar surface structure.
