Food Grade Printing with the N-Series

Have you ever seen an egg or piece of meat with a mark printed on it and wondered, 'can I eat that?'. The answer is, yes, you can. The mark on your food items is produced using food-grade ink, and here at Needham Ink Tech, we produce a wide range of high-quality food-grade ink with a new and improved formula for our own N-Series CIJ coding machines. So, what is food-grade ink and where is it used? Let's explore!


What is food-grade ink?


Food-grade ink is a specific formulation of ink that is produced to be compatible with inkjet printers, and which can be printed either directly onto food or onto food packaging without posing any risk or harm to those consuming the food items. While traditional solvent-based inks are manufactured using methyl ethyl ketone (MEK) which is toxic to humans and animals, food-grade inks typically use food-grade ethanol; food-grade ethanol is a powerful natural human-safe solvent due to its purity and lack of additives and is useful for lots of food-safe applications that may come in contact with people.

Inks used in CIJ printers for coding onto food and pharmaceutical products are subject to regulations set out by national governing bodies. Needham Ink Tech food-grade inks are designed to meet these regulations and can be used to code in both food and pharmaceutical applications.

Where is food-grade ink used?

Food-grade ink is used for a number of specific printing applications. Here are some of the main ones:

black and white cowHealth marking

Nowadays, all meat has to be traceable from the moment it enters the food chain. A health mark is applied to fresh meat that has been produced in licensed premises in accordance with the regulations, under veterinary supervision. It is an internationally recognised symbol indicating that the meat has been inspected and passed as fit for sale for human consumption.


Pills need to be marked with identification data to ensure that they aren't counterfeit, or tampered with in any way. They need to be clearly marked with the name of the drug they contain, as well as dosage information. Inkjet printing solutions are particularly suitable for implementing requirements for the identification of medicines. Inkjet printing can be used to generate both characters and 2D barcodes at high print speed and quality and apply them to a variety of surfaces and materials. 

Egg printing

You won't find an egg without a mark printed onto it if it's being sold from a large farm or facility. The egg marking ink is formulated to comply with food safety standards and is applied directly onto the egg. The egg ink helps businesses worldwide to correctly label products and meet quality standards.

Food Packaging

Safety is a necessity when it comes to any ink, but it’s particularly important for printing on food and beverage packaging substrates that are composed of a wide variety of different materials. Food-grade ink is commonly printed on:

  • Flexible plastics
  • Shrink sleeves
  • Tin cans
  • Glass bottles
  • Corrugated cases and cartons
