    Default Permanent ink to mark parts

    Sometimes the customer calls for a "Contrasting Black Permanent Marking" on the parts.
    Sometimes for White.

    I've had a bottle of ink, don't remember where I got it.. For stamping on the part number and revisions.
    Any recomendations for inks, ink pads etc?
    Something from MSC, or McMaster? Or the local print shop?

    Is there such a thing as ROHS compliant ink??

    My shop, permanent ink = Sharpie!


    OK, OK, sometimes I will use a paint pen. LOL
    But nothing more substantial then that.

    I frequently use those acid etching pens, that is the only thing that I can think of that is really permanent. It won't obviously work on stainless parts but other things it works very well on.

    What the customer wants is a 10 digit part number and revision stamped onto the part.
    Typically, .2" high characters, I have a small set of rubber type on a handle.
    I've also just engraved them in with a 1/16" or 1/32" ball mill.

    What I am looking for is a suggestion for the appropriate ink.
    They have a strange idea that they want very neat looking parts, to build multi million dollar machines. Go figure.

    The link I posted has permanent metal-marking ink, solvent-resistant ink, high temperature ink, etc. There are other companies out there as well.
