The most direct effect of the increase in ink viscosity of the printer is the flow rate of ink in the pipeline, resulting in nozzle missing.
 
Why is the nozzle frequent blocking? The change of viscosity indirectly affects the surface tension of the ink. The surface tension of the liquid is the attraction of molecules inside the liquid to molecules on the surface of the liquid. When the viscosity increases, the shear resistance between molecules increases, thus indirectly affecting the surface tension of the liquid. At the moment when the ink droplets are separated from the print head, if the tension is too high, the ink droplets will not be ejected, and ink droplets will remain on the surface of the printhead, resulting in non-particle blocking.Another characteristic of the composite solution is that at low temperature, the solubility of the composite solution is relatively low, and some solutes are often precipitated.
 
If the ink is precipitated, the precipitated substance will also cause the damper and print head to be blocked.The most direct factor for the above situations is temperature. Low temperature also affects the adhesion between ink and media.  Increasing the indoor temperature is crucial to the stability of ink during printing.
 
In the same ink, when the temperature is lowered, the viscosity will become larger, so it is easy to "break" when printing at high speed. Many inkjet printer users will think that the printhead is blocked, but after cleaning, it will be normal immediately, but it will not be long before it is repeated. Some customers will think it is a problem of ink quality and is the problem of ink absorption and drying. If the temperature is too low, it is not conducive to the absorption of ink by the coating of the printing media, nor to the volatilization of the ink , thus causing a "pile of ink" phenomenon. Therefore, the majority of users try to maintain a suitable temperature when using in cold weather, which is conducive to the normal operation of the printer.
 
Under the influence of temperature, the consistency of ink will change, which is a physical phenomenon, but what changes is the form, and its essence will not change.
 
The printer ink becomes thicker and the viscosity becomes larger. However, it is not recommended to pour thinner or ink blending oil into the ink for blending to change its viscosity. Because when users use these additives for ink blending, you do not know the total amount of various additives that the ink can contain, which is easy to exceed, and will affect the performance of the ink and the printing quality.
