    Bar Code materials?

    I'm trying to make some QR codes (bar codes) and am having difficulty finding a correct material. I have played with some Laser Max and LaserLites material with no luck (yet). Does anyone have a suggestion of materials and what color combination works best. I guess I'll have to invert the image in Corel but that will depend on the color combination. As always....thanks

    How durable does it need to be? I find black anodized aluminum plate to offer very high contrast and great resolution for even the smallest of QR codes.

    Dan---I haven't tried anodized alum. yet but I will tomorrow. I do have concerns about durability, but one step at a time.

    I know ordinary white engraves black or yellow engraves black plastic works fine for normal barcodes, I've never tryed it on QR codes..
    Epilog 24TT(somewhere between 35-45 watts), CorelX4, Photograv(the old one, it works!), HotStamping, Pantograph, Vulcanizer, PolymerPlatemaker, Sandblasting Cabinet, and a 30 year collection of Assorted 'Junque'

    Every time you make a typo, the errorists win

    I Have to think outside the box.. I don't fit in it anymore

    Experience is a wonderful thing.
    It enables you to recognize a mistake when you make it again.

    I like the black anodized aluminum. It's more durable than you might think. Depending on the application laser sublimation on silver or brass colored aluminum might be satisfactory.
