| 英文摘要: |
| Ink layer thickness on the printing plate greatly influences uniformity of ink transferred to the substrates, which is an important indicator of printing quality, so the study of ink layer and its thickness is important for improving the quality of printing products. Ansys CFX is used here to build a model of ink fluid adhering to lower vibrator roller, form inking roller, and printing plate for analyzing ink transferring in inking process.Ink layer thickness on each position of the model is acquired to analyze the forming mechanism of ink layer on printing plate, as well as the influence of oscillation speed of lower vibrator roller and dot area percentage of plate on ink layer thickness of printing plate. It can be concluded that, in the case of fixed ink supplying amount, ink layer thickness increases along with the increasing of oscillation speed, and decreases when the dot area percentage is getting larger and the minimum is got when the dot area percentage is 100%. At last, experiment of plate inking on print ability tester verifies the correctness of the simulation analysis. |
