Have you tried a watermark fluid, it will give a better result than just a black surface.
Edit. Are these the same stamps you asked about back in February, as we were not able to help much then either.

According to my old SG commonwealth catalogue the 16 cent stamp was script ca as you state, but there is a variety for the chalky paper in that it actually has St Edwards crown, which was inserted into the dandy roll where a space had been created because a script CA crown had fallen away at some point.
However none of the stamps should be missing a watermark of some description. It is only the chalky paper that has this wrong crown error.
