A method of minimizing errors in the machining of printed-circuit boards, machining patterns, printing tools or the like is disclosed. First, the variations of the actual or basic grid of the existing printed-circuit board or the like from a given theoretical reference grid are determined; thereafter, the reference point of the machining operations is selected on the basis of said variations such that the actual variation between actual and theoretical reference grid is minimal.
