Abstract

The invention discloses a test system and a test method for testing the performance of digital printing ink, belonging to the technical field of digital printing ink performance. The invention comprises an ink supply unit, a nozzle, an ink drop observer, a control unit and a droplet suction device; the ink supply unit is connected with the nozzle through an ink tube, and is used for supplying ink to the nozzle; the control unit is electrically connected with the nozzle, and is used for controlling The nozzle sprays ink; the control unit is electrically connected to the ink drop observer, which is used to control the ink drop observer to observe and record the shape of the ink droplets ejected from the nozzle, and transmit the recorded information to the control unit; the droplet suction device is located in the nozzle The bottom of the nozzle is used to collect ink droplets ejected from the nozzle and droplets generated during inkjet. The invention quantitatively evaluates the performance of the ink by testing the ejection speed, the shape of the ink drop, the volume of the ink drop and the ejection stability for a long time, the data is accurate and reliable, the cost is economical, and there is no waste of substrates and ink.

Description

technical field [0001] The invention belongs to the technical field of performance testing of digital printing inkjet printing, and in particular relates to a test system and a testing method for testing the performance of digital printing inkjet printing. Background technique [0002] The development of inkjet technology is changing with each passing day, and the application of inkjet printing in the field of digital printing is also gradually increasing. Digital printing machines based on inkjet technology are becoming more and more popular. Inkjet printing ink is an important part of inkjet printing materials. Its quality and performance are closely related to the quality of digital printing, which greatly affects the use effect of the printing system. To achieve excellent printing characteristics, the printing ink, printing substrate and printing system must match. Different characteristics of the printing substrate require different ink characteristics to correspond to...
