AbstractIndicia such as farm codes are printed onto eggshells using an ink which is invisible under visible light but visible under UV light. Preferably the eggs are also subjected to a step of printing with an ink visible under visible light. Since the UV fluorescent ink is not visible under visible light it does not interfere with the visible indicia. Suitable UV fluorescent colourants are curcumin, quinine, riboflavin, caffeine and erythrosine.
