Temperature-sensitive inks are also known as thermochromic inks, thermal-sensitive inks or temperature-indicating inks. Temperature-sensitive inks fall into three main categories: the ink shows a certain specific color at normal temperature, the color disappears and becomes colorless after being heated, and the original color is immediately recovered after being cooled, and the ink is called as reversible temperature-change decoloring ink because the change process is reversible; the ink is colorless at normal temperature, changes into another color after being heated, and returns to the original colorless after being cooled, and is called as reversible temperature-change color-developing ink because the change process is reversible; the ink displays color at normal temperature, changes into another color after being heated, and is called reversible temperature-change color-change ink because of the reversible change process.
the temperature-variable (thermosensitive color-variable) water-based flexographic printing ink and the water-based gravure printing ink thermosensitive water-based flexographic printing ink are suitable for enterprises of mass packaging production, and can be prepared into corresponding inks for various types of flexographic printing machines. The printing ink is mainly applied to large-batch package printing of famous brand products such as cigarettes, foods, beverages, pesticides and the like. The thermochromic water-based anti-counterfeiting ink meets the environmental protection requirement on the existing tobacco packaging. The cigarette package printing machine accords with the national relevant policy guidance, is popular with a plurality of cigarette factories due to attractive appearance and convenient detection, and lays a good foundation for occupying the market of cigarette package printing enterprises.
However, in the application process of cigarettes, especially in the printed matter wrapped outside the cigarette case, because the thermosensitive color-changing speed of a single pattern is high, the situation that the local heating of the cigarette case is uneven can easily occur in the handheld process, thus, the color change of different positions of a pattern is asynchronous, the target color-changing color of the target pattern cannot be integrally presented, and the color significance of the temperature-changing ink design printing is lost.
