GRAVE bug with shadows

[Thomahawk]

Shadows, despite set to 100% black and multiplicate, are NOT. They should work exactly the same like overprinting, just overlaying the underlaying colors. Even worse in separation they show to LIGHTEN the underlaying color. This is extremely bad! See example files attached.

I don't believe this is the case..., i.e., the shadow set to 100% Black and Multiply is just that... Your shadow has 38% opacity...

 

This is how it looks when the shadow is set to 100% opacity...

 

and just to prove the point, I've changed the orange (M65, Y100) to Cyan (C100) and left the shadow at 38% opacity to make the maths easier. Multiply by it's very nature is a combination of the blend colour and the underlying layer which means that the two combined should always total 100% which they do for the complete length the shadow gradient...

I have this problem also - it's so frustrating.

Because of this bug, my clients logo couldn't get a shadow effect on some white text on a 0,50,0,0 background.
