If you have ever purchased one of our games in a retail store, chances are the game came with a cardboard box wrap-around...or, as we call them in our office, an "O-card".
If you tilt the box in the light, and rub your finger over the front, you can see and feel the bumps of the raised image (or "relief"). This process is called embossing, and creates a sort of new dimension to the illustration.
Here we have one of the embossing plates used for this process. When we press the card stock (that is to become the box) in between these two plates and apply pressure, the card stock is then imprinted and voila! You are left with a marvelous box design! Note: This plate in particular is one of the few that actually embossed the boxes. There is a chance that this very one embossed your game!
