How to get the best clear transparency (black transparency issues)

I’ve been using warning signs lately and images with black in them. Allot of them have had portions that are 0,0,0 black. Even trying to shift the colors a few rgb away from true black zbrush still isn’t cutting clear lines. and what if I need transparency around a black edge like here (attached). It makes the line jagged.

When I do it in lightbox I don’t even have the option to turn black transparency off or antialias.

Do these options not exist, and how can I get clear boarders with lots of black in my photos.
