Why not just print a board? You have a spare board for your profile right? When you are done you have a working program and you know if the stencil is correct.

Pd/Ag doesn't usually dissolve (leach) nearly as bad as Ag only. In my hybrid days, we would use 62/36/2 solder. The 2% silver helps saturate the solder joint and thus keep the Ag from being leached away by the Sn.
