How to have transparents decals without shadows under ?

Hi, I'm trying to put some decals like one glued to a wall, on a plane, with one material for the gfx on the decal, another material is fully transparent, and there is a mix texture for blending them.
The space between wall and decal is about 0.001 cm. My problem is when transparent material is close from wall, it casting a shade on it. I've done lot of tests, same result.
The only solution i have now is to vectorize the decal and import it as .ai in max, but that just a workaround...
Here a screen for exemple :
any ideas ??

why you use mix material?
put the mask in the opacity slot of a glossy mat

yeah, i also tested it like this before, same results... (and i tried mixing with other types of materials too)
screen with only a glossy mat + opacity map. Png is 24b, same results with 8b, 24b without alpha, and 24b jpg, i checked that white is really white too.
When the plane is less close, things goes better... that's like an AO effect
Same things with PCM too

did you try to set alpha image's gamma value to 2.2?
