Method for the production of panels from a board, press plate, method for the production of a board and board

A method for producing panels from a board, the method comprising:

• providing a board comprising a core material board laminated with a laminate material layer onto a surface of the core material board forming a laminated surface of the board, said board having at least one impressed region, comprising at least one impression of the laminated surface, said at least one impression has a linear progression and extends completely over the laminated surface of the board, wherein in cross-section perpendicular to the extension direction of each of the at least one impression said impressed region having transitions at each outermost region of the impressed region where a transition of the surface to a bottom of the impressed region occurs, said transitions having a width and being adjoined by a part of the impressed region where the bottom of the impressed region is parallel to the surface of the board,
• linearly dissecting the board along a dissection line running in each of the at least one impressed regions in one or more dissection steps to produce raw boards with a dissection means having a dissection width,
• milling out pairing mechanical locking means at opposite edges of the raw boards, comprising a first mechanical locking means having a first width and a pairing second mechanical locking means having a second width,
• wherein the at least one impressed region having an overall width, wherein the overall width is equal to a sum of the dissection width, the first width of the first mechanical locking means, the second width of the second mechanical locking means, the width of the transitions, a sacrificial machining width, and a manufacturing tolerance, said manufacturing tolerance being calculated as 0.10 to 3.0-fold of the dissection width.
