摘要：A screen skeleton as a cathode is subjected to a pulsed current for depositingmetal from an electrolytic bath onto the metal regions of the screen skeleton, saidelectrolytic bath containing a brightener of the second class. This process involvesgrowth of metal substantially perpendicular to the screen skeleton surfaces thusmaintaining the size of the openings of the screen skeleton.

< P>Small pulse current durations are advantageous. Preferably a pulsed current isused comprising pulse current and non-pulse current durations; more preferably thepulse current durations are subdivided into small pulse current and non-current pulseperiods.
