Hi,

Another way for embossed logo's is to put a mirror image vinyl on the mould and release coat over it.  You will likely need either a thicker vinyl or precisely place a few layers ontop of each other to get a deep recess.

Another method I use which is a bit more subtle is to use the vinyl graphics/ letters etc as a mask. Apply the graphics, Soda Blast the area, peel off the graphics and you are left with a subtle frosted glass finish contrasting the high gloss. Makes a really nice chess board
