We are having problems with our Fab House. If we forget to remove a silk 
screen and it's on a pad sometimes they won't take it off and we are stuck 
with this problem when the boards come back. I am wondering what others do.
I was told you could output your soldermask, bump expand it to a % so the 
soldermask is larger and it conflicts with the 1:1 silkscreen then over lay 
the silk screen and automatically delete all silkscreen inside the larger 
soldermask. Then you save the silkscreen and plot the soldermask at 1:1. 
Reason it gives you a larger margine.

Does anyone have a process that makes this fool proof?

Thanks,
Steve
