Importance and Properties of Safe Food-Grade Ink

It is crucial that you know the ingredients of packaged foods when purchasing them. Well, you should appreciate the fact that food-grade ink is safe for your food product. After all, it does not contain toxic metals such as cadmium, lead, and mercury in even the smallest amount.

More Than What it Seems

It is quite tricky to print on food since the industrial ink needs to be non-smearing and would not stick together. Thus, a certain amount of viscosity and other requirements are necessary. However, the most crucial aspect of the ink is their ingredients. Some utilize UV industrial ink which is not visible to the naked eye but can be detected by UV scanners. Anyway, manufacturers have to use the industrial ink for different reasons, often for coding food products for both safety and security reasons.

Do remember that food-grade ink can either come in direct contact with the food like in dry food packaging or utilized directly for printing on food surfaces. Either way, the industrial ink has to be safe for consumption and contains no toxic metals or compounds.

Ideal Properties

Since food-grade ink-jet printing has the purpose of decorating or printing the surface of different food items, there have to be a few adjustments for the food to have a compatible surface for the ink. Such characteristics include drying times, viscosity, smear resistance, and surface tension.

Anyway, continuous industrial inkjets or CIJ consist of two things, one would be the ink, and the other is the make-up fluid. The make-up fluid first has to be mixed with the ink to ensure the appropriate maintenance of the printed fluid’s chemistry. One of its functions is to “make-up” for any solvent that evaporates to maintain the ideal, consistent ink performance.

Food-Grade Ink Available

You can purchase food-grade ink in different locations since these are readily available nowadays. You may check for local stores near your area, or order them online. A neat recommendation is since they have high-quality food-grade ink, one that you would not regret purchasing.


Food-grade ink has to be safe for human consumption since it either comes in contact with food through packaging or on the food itself. Also, it has to satisfy certain properties, such as drying times, viscosity, smear resistance, and surface tension, that make it viable for the surface of the packaging of the food or on the food. Lastly, it may even include other properties such UV industrial ink’s security features.
