Zona,
A YAG laser WILL mark stainless steel and some other metals, a co2 laser will NOT mark metal. That is where the Thermark & Cerdec come in, they each do the same thing using a little bit different chemical compound. They allow you to put a black mark ON the metal. It really bonds the chemical to the surface of the metal using the heat generated by the laser. The mark is on the surface of the metal and will not be "engraved into" the metal. As Harvey said, it is a medium black mark, not a dark, rich black.
You may want to get a sample to show your customer before switching them over. It is much easier to cerdec/laser than it is to rotary & color fill. Another benefit is you would be able to put barcodes & logos on much easier if the need is there.
