    In packaging printed matter, the ink factor that affects the gloss of the printed matter is mainly the smoothness of the ink film, which depends on the nature and quantity of the connecting material


    1.


    After the paper absorbs the connecting material of the ink to the maximum, the remaining connecting material remains in the ink film, which can effectively improve the gloss of the printed matter


    Second, it is the fluidity of the ink

    The ink fluidity is too large, the dots increase, the printing size is enlarged, the ink layer is thinner, and the printing gloss is poor; the ink fluidity is too small, the gloss is high, and the ink is not easy to transfer, which is not conducive to printing


    Third, it is the leveling of the ink

    In the printing process, if the ink has good leveling, the gloss is good; if the level is poor, it is easy to draw, and the gloss is poor


    Fourth, the content of pigments in the ink


    The high pigment content of the ink can form a large number of tiny capillaries in the ink film


    In actual printing, the use of bright oil to increase the gloss of printed matter is completely different from increasing the pigment content of the ink


    Five, the size of the pigment particles and the degree of dispersion

    The size of the pigment particles in the dispersed state directly determines the state of the ink film capillary.
