You can print prints that show a variety of flavors such as foods, flowers, etc., such as gift cards, New Year's cards, magazines, pictures, etc. For example, if a flower photo is printed on a product catalog, the reader wipes the flowers with the nails. The scent of the flowers is emitted; if the apple is on the tablet, the fragrance of the apple is emitted after the rubbing.

In fact, this kind of printing method is not difficult to understand, is to work hard in the ink, first all kinds of spices into capsules, mixed with the ink to be used, according to the content of the screen selected ink to print on the line. For the printing surface, use a fingernail or a coin to wipe the printed image, break the capsule in the ink, seal it in a broken capsule, and allow the perfume enclosed in the capsule to fly out and temporarily float in the air.
