Table Of Contents

1. Why can edible ink be eaten?

Every component of edible ink complies with international food and food additive use standards or relevant laws and regulations, which is very different from traditional ink. In addition, the production process of edible ink must also meet the relevant requirements of food production. Edible inks are both edible and printable.

2. What is the difference between edible ink and environmentally friendly ink?

Most of the printing inks used on food packaging on the market are environmentally friendly inks, which are inks containing a small amount of volatile organic compounds (VOCs) and cannot be directly printed on the surface of food or medicine. Edible ink is a compound food additive, which is an ink that can be eaten into the human body together with food and medicine after printing (do not eat before printing). It is generally used for surface printing of food, medicine or edible packaging materials.

3. Why does the edible ink solidify into a gel and cannot be used?

1. The customer pours the used edible ink into the original packaging. Since the used ink will oxidize, it will accelerate the deterioration of the unused ink after mixing with the unused ink, causing the system to solidify into a gel. It is recommended that the unused ink be used up. Ink is stored separately.

2. The customer does not use anhydrous ethanol as the diluent but uses water-containing medical alcohol or edible alcohol as the diluent so that too much water enters the ink system, which leads to the deterioration of the ink and causes the system to solidify into a gel. It is recommended that the customer must confirm the dilution The agent is absolute ethanol.

4. Why is there no white edible ink printed with environmentally friendly ink?

1. Because the raw material used in this product is a natural extract, the color of the extract is light brown, so it will affect the whiteness of the finished product.

2. This product does not use any whitening agent or bleaching agent, which does not meet the national standards for the use of food and food additives or relevant laws and regulations.

5. Why does edible ink dry sometimes fast and sometimes slow?

The drying speed of the ink is closely related to the ambient temperature and humidity. When the temperature is high and the humidity is low, the ink dries quickly, then the slow-drying thinner provided by the company should be used; when the temperature is low and the humidity is high, the ink dries slowly, then the fast-drying thinner provided by the company should be used. Customers should do a small sample test before printing, and adjust the appropriate printing conditions or the environment according to local conditions.
