Some designers use layers in their layout programs to isolate elements they want to turn on or off. An example would be a layout containing one type layer for U.S. English audience and a type layer for Spanish-speaking readers.
As part of the design process, you should try using the layers in your page design program to determine which combination of font style works best with your graphics.
I created a simple restaurant menu cover design. Using InDesign CS6, I brought in an image of a salad plate and lowered its' opacity to 20%.

On another layer I created a vertical arrangement of squares with a single rounded corner in InDesign, placing it on its own layer.

Now to experiment with various fonts I selected. Each font is on its own layer.
|Constantin font. Vertical art removed.|
|Fontin typeface, type positioned to upper right|
|American Gothic (typophiles think Copperplate), increased opacity.|
One layout, several looks, one panel. Layers turned on or off:
Give this a try on your next project.
