Figure 1 shows the dynamic surface tension curve of a typical and ideal ink sample.
The surface tension curve of a typical ink also shows three distinct regions, however, the rate of drop in surface tension is not as rapid as an ideal ink.
Dynamic surface tension curve for cyan inks with varying amounts of surfactant are shown in Figure 2.
Figure 3 shows the dynamic surface tension curve for a white ink without surfactant, compared to ink with leveling agent, and silicone surfactant.
The dynamic surface tension curve for ink with silicone surfactant shows a large drop in region 2 and the surface tension value in region 3 is also lower.
The data from the dynamic surface tension curve can be used to predict drop spread on different substrates.
the form of tension curve in dynamic is quite different from the curves in quasi-static.
We find that compression curves are steeper than tension curves, namely, we considered the way of energy absorption in compression is large stress and small strain while in tension is large strain and small stress.
