AutoCAD Inventor :: Render Shaded Or Translucent Object With Painted Surfaces?

I have an interesting question here - How should I try to shaded render this syringe so that a plunger can be seen underneath the translucent body? I need to have the gradiations and labels of the millileters be plainly black.

OR

is there a way to keep those gradations black while rendering an illustration and have the plunger visible beneath the body?

The gradiations are cut into the body of the syringe in this model, and the surfaces of the gradiations are changed to black.

Have been adjusting the color styles - but perhaps I'm missing something. Making the material translucent just fades the gradiations on the syringe, I'd like.
