In gravure printing, ink resolubility is also a key indicator to test the performance of ink. Especially in the color ink printing, the moderate resolubility can not only make the color fully displayed, but also solve the problem of shallow plate mesh blocking and overprinting cross-color.

In color ink printing, according to the different hue requirements, the depth of the ink hole mesh of the printing plate is different, the amount of ink transferred to the surface of the substrate is also different, the volume of the ink hole is large, the amount of ink filled in the printing process is large, and the film layer transferred to the substrate is thick; The inking hole volume is small, the amount of ink filled is small, and the film layer transferred to the substrate is thin. As a result, a dense and colorful picture is formed on the substrate.

Inks with poor resolubility, in the shallow screen part of the plate due to the high-speed rotation of the cylinder in the ink tank, the residual ink is not easy to be re-dissolved by the ink in the ink tank, resulting in the shallow printing of the net hole, and eventually causing the blocking accident. For inks with good resolubility, the printed ink is easy to be dissolved by the ink solvent in the printing plate during the overprinting process, resulting in ink crosstalk problems.
