An ink composition comprising:
- a base epoxy ink;
- a pigment;
- a catalyst;
- a first wax treated silica powder having an average particle size of about 4 to 6 microns, a melting point of the wax of about 65 to 85° C., and a pH of about 7;
- and
- a second wax treated silica powder that has a different porosity than the first wax treated silica powder and having an average particle size of about 4 to 6 microns, a melting point of the wax of about 65 to 85° C., and a pH of about 7.
