AI Technical Summary

Problems solved by technology

At present, the electrohydrodynamic printing of multi-dot matrix patterns usually adopts the printing method of single nozzle, which takes a long time and has low efficiency to print dot matrix patterns.

Using the multi-nozzle printing method, because the distance between the nozzles is fixed, only dot matrix patterns with a specific pitch can be printed. Dot matrix patterns with different pitches require multiple nozzles with different pitches, resulting in high printing costs for dot matrix patterns. , so the electrohydrodynamic printing method of fixed-pitch multi-nozzle mode is rarely used in the electrohydrodynamic printing process of dot matrix patterns
