In the process of homogenizing ink, heat transfer ink is required to have larger thixotropy and rheology, using the thixotropy of ink, under the action of frequent stress, ink viscosity decreases, conducive to ink leveling. The viscosity of the ink and the silk head should be appropriate, the viscosity is poor, the silk head is too short, can not ensure the normal transfer and reasonable distribution of ink; The viscosity is large, the silk head is long, the ink is not even on the ink roller, and the distribution is uneven, which is easy to produce serious flying ink phenomenon.
When the inking roller transfers ink to the printing plate, from the point of view of improving the printing quality, the rheological properties of ink can have the following requirements: the viscosity can not be too small, the fluidity can not be too large, the original thixotropic structure should be restored at this time, so as to control the dot expansion value.
In addition, cots printing adaptability also has an important effect on the ink homogenization and inking.
