A printed circuit board having a circuit pattern formed on at least one of the first and second faces of a substrate and having characters and symbols representing components to be mounted on said substrate printed on the first face and the second face of the substrate, wherein the characters printed on the first face have been printed in the reversed images in about the corresponding positions of the back face. Since the characters printed on the first face of the printed circuit board are also printed in the reversed images in the immediately corresponding positions of the second face of the board, these characters can be used as indexes to find a particular position on the printed circuit board, and the first or second face can be instantly distinguished from the second or first face. The present invention also provides a method for the fabrication of a printed circuit board comprising the steps of printing on the first face of a substrate which has a circuit pattern formed on at least one of the first and second faces of the substrate with a first printing plate on which characters are disposed, preparing a second printing plate having the reversed character images by turning over the above first printing plate to reverse the normal characters, and printing the reversed character images on the second face of the substrate with the second printing plate.
