About this font family
Penitentiary Gothic is a digital recreation of the letters used on California state license plates, designed in order to make props for movies and television shows.
The regular style is meant to be used on its own, but the other four styles are meant to be used one on top of another in different colors to create an embossed 3D effect. For best results, use the fill style in a dark color on top of a light colored background. Put the lolite style directly on top of the fill style in 10 - 30% of the background color. Put the hilite style directly on top of that in 10 - 30% of your fill color. Put the shadow style directly on top of that using your background color plus 50 - 80% black.
