تشير قابلية بلل الحبر إلى إمكانية تطوير الحبر بالتساوي على سطح الطباعة, which is closely related to the contact of the surface of the printing material. Viscosity is an important physical property of ink. It refers to the internal resistance caused by the interaction between molecules inside ink. It is usually used to describe the viscosity of ink.

تأثير اللزوجة على قابلية بلل الحبر

Viscosity has an important effect on the wettability of ink. خاصة, the ink with too high viscosity is easy to form uneven film when it comes into contact with the printing material, resulting in the ink difficult to evenly wet the surface of the printing material during printing, thus affecting the printing quality. فضلاً عن ذلك, too high viscosity ink will also reduce the ability of ink transfer to the printing material, affecting the printing speed and efficiency of ink.

على العكس تماما, too low viscosity ink may form too thick ink film on the surface of the printing material, resulting in increased ink fluidity, difficult to maintain stable printing quality during printing.

لذلك, the viscosity of ink has an important effect on its wettability. في التطبيق العملي, it is necessary to select the appropriate ink viscosity according to the characteristics of printing materials and the requirements of printing technology, so as to ensure the uniform wetting and transfer ability of ink in the printing process.
