What Do We Need While Printing on Food?

Food-Grade Ink: Ink used in food printing are made from food-grade materials so that they are safe and edible. Edible ink can also be extracted from natural food coloring and usually do not contain toxic chemicals.

Printing Process: Food is put into an edible food printer, and the food printer prints food-grade ink on the surface of the foods, just like a normal printer deposits ink on paper. The process can be similar to inkjet printing, where tiny droplets of ink are sprayed onto a surface, or it can involve a flatbed printer that uses a roller to apply the ink.

Drying/Curing: After printing, the ink needs to dry or cure on the surfaces of foods. This can occur naturally or be accelerated by drying or curing processes (which may involve heat or light), depending on ink and printer technology.

Quality Control: After the ink is dry, the quality of the printed food is checked. This includes checking for proper ink adhesion, color accuracy and overall visual appeal.

Consumption: The final step is to consume the printed food. Since edible ink is food-grade, they are safe to eat and should not affect the taste or safety of foods.
