What effect does dispersed sublimation ink viscosity have on the print head?

The most direct effect of the increase in dispersed sublimation ink viscosity of the printer is the flow of ink in the tubing, which causes the ink to break. The change of viscosity indirectly affects the surface tension of the ink. The surface tension of the liquid is the attraction between the molecules inside the liquid and the molecules on the surface of the liquid. When the viscosity increases, the shear resistance between the molecules and the molecules increases. It also indirectly affects the surface tension of the liquid. At the moment when the ink droplets leave the ink head, if the tension is too large, the ink droplets will not be ejected, and ink droplets will remain on the surface of the nozzle, resulting in non-particle plugging.Another characteristic of the composite solution is that the solubility of the composite solution is relatively low at low temperatures, and some solute is often present.

 Dispersed Sublimation Ink

If the dye sublimation ink appears to be precipitated, the precipitated material may also cause the ink bag and the ink head to become clogged. The most direct factor in the above cases is the temperature, which also affects the adhesion between the ink and the medium. Increasing the room temperature is critical to the stability of the ink during printing.

The same ink, the temperature is lowered, the viscosity will become larger, the viscosity is too large, and it is prone to "broken wire" at high speed printing. Many inkjet printer users will think that the nozzle is blocked, but once cleaned, it will be normal immediately. It will not repeat for a long time, and some customers will think it is a problem of ink quality. This is followed by the problem of ink absorption and drying. If the temperature is too low, it is not conducive to the absorption of ink by the inkjet coating, and it is not conducive to the evaporation of the solvent of the ink, resulting in "stacking" phenomenon. Therefore, the majority of users should maintain a suitable temperature when using in cold weather, which is conducive to the normal operation of the printer.

Dye Sublimation Ink

Under the influence of temperature, the thinness of the ink changes, which is a physical phenomenon, but the change is the form, and its essence is not changed.

The inkjet sublimation printer ink becomes thicker and the viscosity becomes larger. However, it is recommended not to use thinner or varnish to pour into the ink to reconcile and change its consistency. Because when users use these additives to adjust the ink, you do not know the total amount of additives that can be accommodated by the ink. It is easy to exceed the amount, which will affect the performance of the ink and affect the print quality.
