Common methods for testing the properties of water-based inks

The method of testing depends on the type of performance and metrics to be tested. Here are some common methods that may be used to test the performance of water-based inks:

Printing effect test: Use a printing press or sample printing equipment to print in accordance with standard test methods and requirements to check and evaluate the printed matter. Aspects such as clarity, color accuracy, gloss and adhesion of the pattern are usually checked.

Stability test: In the laboratory, the ink is placed under different environmental conditions, such as high temperature, low temperature, humidity, etc., to observe its performance. It is also possible to test the stability of the ink on different media, such as paper, plastic, metal, etc. Evaluate its drying speed, fading resistance and other aspects.

Printing speed test: Use standard test equipment to test the printing speed of the press and record the length or area of printing per minute.

Wear resistance test: Use standard test methods to test the wear resistance and scratch resistance of the ink on different media. Evaluate its performance against wear and scratching under different conditions.

Viscosity testing: Using test equipment such as a viscometer, test the viscosity of the ink and assess its coating uniformity.

Packaging tightness testing: Using standard test methods, test the tightness of ink packaging and evaluate its performance during storage time after use.

Before the test, it is necessary to formulate the test plan and test process, clarify the test objectives and indicators, select the appropriate test equipment and methods, and record the test results and data. After the test, it is necessary to analyze and evaluate the test results, put forward improvement measures, and continuously optimize and improve the performance of water-based ink.
