Knokcout black tint on spot color - AI and InDy

[rickself]

Problem - I have some black type, 70% tint of black on a 100% spot green background. It's part of a 7 color job. 4 colors on the first pass, 3 spot colors on the 2nd pass. The 70% black tint is not knocking out of the green background.
The art file is built in Illustrator and placed into InDesign for imposition. I create a PDF and drop it into the RIP but the black is overprinting.
There HAS to be an Illustrator way to get the 70% black to knockout.
HELP!!

There is. Get rid of the transparency applied to it..

OK Joe, I'm feeling stupid here but...
How do I do that.
Been doing this 30 years and I don 't know how to turn the transparency off on a tint.

And they have the transparency set to Darken 100%

All right - I got it figured out.
Thanks, Joe!
