The invention relates to a method for generating an optimized 2D or 3D roller profile curve (5), having a prescribed desired 2D or 3D roller profile curve (5) of a roller profile (5) that changes along a rolled material feed direction (X) and actuating a flexible roller profile device, in which profiling rollers (11) can be adjusted in a computer-controlled manner during a roller profiling process. The method for generating the optimized 2D or 3D roller profile curve comprises the following: a) entering the desired 2D or 3D roller profile curve (5) by means of CAD tools; b) calculating the optimized 2D or 3D roller profile curve (5) from the input and desired 2D or 3D roller profile curve (5) using rounding algorithms, wherein the rounding algorithms round off the 2D or 3D profile curves (5) at a substantially constant curvature, so that the optimized 2D or 3D roller profile curve (5) is generated accordingly, substantially avoiding an uneven curvature; c) confirming or modifying a region of the optimized 2D or 3D roller profile curve (5); and d) saving the optimized 2D or 3D roller profile curve (5).
