In many countries, eggs are subject to labeling requirements. The European Union requires that the printing and coding on eggs consist of an alphanumeric code made up of:

• a number indicating the method of production
• a two-letter code for the country of origin
• the hen laying establishment registration number

Inks used for egg printing must comply with regulations for food marking inks. Generally, the stipulation is that inks used on food items must be safe for human consumption, whether the food item is raw or cooked.

Also, tolerances might exist for legibility and the presence of markings on eggshells. So, choosing a reliable egg printer that can deliver the print quality and repeatability is essential.

Marking eggs with logos can help with product branding and differentiation. And, this can play a role in assuring customers that your brand offers superior quality and nutritional content.
