Multi-layered revealable substrates and methods of producing and using said multi-layered substrates

A multi-layered revealable substrate comprising:

• a first layer of a first opacifying material;
• a first color material disposed on a first side of the first layer of the first opacifying material, wherein the first layer of the first opacifying material covers the first color material and the first color material is at least one first ink comprising one or more first colors;
• a second layer of a second opacifying material disposed on a side of the first color material that is located opposite with respect to the first layer of the first opacifying material;
• and
• a second color material disposed on the second layer of the second opacifying material, wherein the second layer of the second opacifying material is disposed between the first color material and the second color material and the second color material is at least one second ink comprising one or more second colors,
• wherein
• the first opacifying material is configured to, upon application of first predetermined energy, change from the opaque state to a transparent state to reveal at least a portion of the first color material underneath the first opacifying material,
• the second opacifying material is configured to, upon application of second predetermined energy, change from the opaque state to a transparent state to reveal at least a portion of the second color material underneath the second opacifying material, and
• the first predetermined energy is a different predetermined energy than the second predetermined energy.
