1. A printing method for producing a variable color image upon a receiver, said printing comprising the steps of:
a. depositing a static layer of toner to form a predetermined multi-channeled layer;
b. depositing a second layer of one or more toner nodes over the static layer, said toner nodes substantially undetectable in a first state;
c. depositing a top layer of laminate over said toner nodes, said top layer and the multi-channeled layer defining an expansion space adjacent said toner nodes; and
d. activating the one or more toner nodes into said expansion space to create a predetermined human detectable alteration of said layers.
