Kasey,
It isn't exactly embossing. It is Hot Foil Stamping and you can get an economical machine that you do yourself.
Veach Company is the supplier and they have been in the business for many years. If a lab does actual gold/silver foil stamping, they will usually have a Veach Co. Machine. You can actually get several other foil colors as well...red, blue, green, black, copper etc. and not just the standard gold/silver.
Cost is about 440.00 for the machine, then you would have a typeset and or logo. Depends upon what you want to do. Foil is relatively inexpensive and will do alot of prints. If you have specific questions, just fire away. I use Veach and have for a while. Good place to get this product from and they are experts in the field.
