Abstract (en)
Production, by electroforming, of perforated frames used especially for making up flat or cylindrical printing frames. According to the invention, the procedure is in two stages, with two separate electrochemical baths, the second bath containing a pyridinium compound of general formula: <IMAGE> in which: - R is an optionally substituted alkyl chain - R' is a hydrocarbon atom or a substituent group in any position relative to the nitrogen atom of the pyridinium nucleus.
