Bullseye Black
 

So I have the regular black and the stiff black.

Both bleed! The regular bleeds more than the stiff but the stiff still bleeds enough to mess up and partially swallow my design.

Anyone else have this problem?

Is there anything I can do to not have this happen?

Is there another BE black that does not bleed that I don't know about?

The stiff black is promoted as not feathering out as much, but I have the same problem you do. There is not another black that I am aware of. We should all email BE and ask them to make a new black for us!

I don't have that much of a problem with the stiff black bleeding - heck, most of the time I like the bleeding. The black stringer - whatever that is - doesn't seem to bleed as much as the regular black. Most of the time I use that for drawing lines.

Try some Armstrong sheet glass in black if you can find it. Pull it into fat stringers. Armstrong is 90 COE too. I combine it with bullseye.
