#$%^&*AU2015264799B220170810.pdf#####Abstract A method for thermal printing of a thermally printable photonic crystal material or assembly, the method comprising: providing the photonic crystal material or assembly, wherein the photonic crystal material or assembly contains voids, and the photonic crystal material or assembly has a void volume, the photonic crystal material or assembly having an optically detectable change in its reflection peak and a decrease in its void volume when exposed to a temperature equal to or greater than a thermal threshold of the photonic crystal material or assembly; and exposing the photonic crystal material or assembly to a heat source, the heat source being controllable to selectively apply heat to one or more portions of the photonic crystal material or assembly and not to the remainder of the photonic crystal material or assembly; wherein the heat being applied is equal to or greater than the thermal threshold of the photonic crystal material or assembly, in order to cause an optically detectable change in the one or more heated portions of the photonic crystal material or assembly. 7180661 1 (GHMatters) P95512.AU.1 27/11/20151/4 ~ T: ~.-. ;*TiT2 T3 FIG. 1A
