The key point of this printing method is to encapsulate the fragrance into the capsule, and then mix the ink as needed.
1. Recourse to olfactory printing
Speaking of printing, it is always an impression that you look at it with your eyes. In fact, it is indeed based on vision, but reality has changed and it has not been possible to resort to olfactory printing. This is the method called scent printing (microcent). You can print prints that show various fragrances such as food and flowers, such as gift cards, New Year's cards, magazines, and picture albums. For example, if you print a photo of a flower on a product catalog, the reader rubs the flower with your fingernails It emits the fragrance of flowers; if it is an apple on the slice, it will smell of apple after rubbing.
In fact, this printing method is not difficult to understand. It is to work hard on the ink, first make all kinds of spices into capsules, mix it with the ink to be used, and select the ink to print according to the content of the screen. Aiming at the printing surface, rub the printed screen with nails or coins to rupture the capsule in the ink, rupture the capsule, and the fragrance enclosed in the capsule will fly out and temporarily float in the air. This fragrance smell has a longer retention period in prints.
2. The impression caused by the color and fragrance is just right
The spice ink that can print fragrance is transparent. The entire printing process is that the color and graphics on the screen must be associated with the fragrance. When the base image is printed with offset printing, silk screen printing and spice ink are used to print the fragrance parts such as flowers or food, usually always Printed in such a two-step process, the effect is very good.
The reason for using screen printing to avoid damage to the capsules in the fragrance ink, and because the thickness of the screen printing ink film is about 20 times higher than that of offset printing, this is convenient for the long-term retention of fragrance, but recently it has been developed specifically for offset printing Special ink. For example, a general offset press can be used. That is, the five-color machine or the six-color machine will print out the base map and the part with fragrance ink in CMYK and other colors at once. At this time, special care should be taken not to damage the capsules in the fragrance ink.
Attention should also be drawn to ink manufacturers, due to the characteristics of the printing method, the method of manufacturing ink should also be changed accordingly. How long is the durability of the spice ink. If you use screen printing ink to print, it can be saved for about 10, and it will have a fragrance when rubbed at any time. If the ink used for offset printing is used, it may be retained for half a year to a year.
