It is not really a reinforcement, it seems it thickens up the layer in  
those large areas.

Thin traces work allright with silicone paper, but 1mm and up already  
causes trouble.

Maybe with another printer with a heavier toner layer it would be better.  
This one is very see-through even on darkest setting.
