System and method for testing ink printing smoothness through ink droplet viewer

The invention relates to a testing system and method for ink printing smoothness, in particular to a system and method for testing the ink printing smoothness through an ink droplet viewer. Accordingto an existing smoothness evaluation method, only qualitative evaluation can be carried out, and accurate data is hard to obtain. To solve the existing technological problems, the testing system and method for testing the ink printing smoothness through the ink droplet viewer are provided. The testing system comprises the ink droplet viewer and an intelligent control system. An ink droplet vieweranalytic system records and transmits ink droplet shape and performance data to the intelligent control system. The intelligent control system carries out data analysis and outputs testing results. Indexes of the spraying speeds, the ink tail lengths, the ink droplet volumes and the spraying stability serve as indexes of smoothness evaluation, and the evaluation standard of the smoothness is defined.
