The consumer and production industry is vast. There are thousands of products that have different requirements when it comes to labeling. This is why industrial ink is such an integral and exciting sector. Each industry that requires labeling has its traits which demand different methods and processes.
Especially in the food and beverage industry, safety is the top priority when labeling. All industrial ink has to be food grade and approved by the FDA. A dry tone is the best option in this area.
Migration and Food Safety
Migration is the strictest aspect of this industry. It involves the prevention of food labeling being transferred to the product itself, to avoid any contamination. Let’s look at a few factors that affect migration of labeling onto food products:
- Dry tone and food safety
- The make-up of the food safety labels
- The various types of coatings
- Temperature – when it’s warmer, migration is more likely to occur
- The nature of the food – when foods are drier, they are less susceptible to migration than foods full of fat
Dry toner wins when it comes to chemical composition and migration in the industrial ink arena. One of the biggest reasons for this is that dry toner is made from pigment. Pigment is an ingredient that is incapable of migration, making it safe and reliable. No liquid substances are involved which means that there is no risk of movement.
Liquid toner is unsuitable for the job because there is a risk that some particles will remain when being transferred. They then can get into the food product.
Water-based industrial inkjet printing doesn’t tend to have a high migration factor. However, it is not often used in the labeling of food products. Primers can reduce the issue of migration, but they often increase the cost of inkjet printing, making it a less economical process.
Image quality is a high priority when being produced for food labeling. Food always sells better when the packaging is aesthetically pleasing to the eye, which means that the process of putting the label on the packaging must be efficient but high-quality.
Dry toner is the best option when it comes to food labeling. Its consistency and high resolution mean that it is easily the best option. It’s consistent, reliable, and not as likely to cause errors or migration. It is undoubtedly the best method when it comes to food packaging.
