To get the most realistic effect with a chromatic typeface like the Circus Freak font, use a different texture for each layer. Or use the same texture but flip it horizontally and vertically.
Letterpress kit 1 contains 5 high resolution rolled ink textures. The textures can be used give your designs that old school letterpress print effect.
The pack also comes with my new font Circus Freak. It has four styles that can be used with the textures to get a printed effect.
