Freeze-thaw stability test method
The ink that is a liquid solution at room temperature is solid at low temperature (such as -20°C) and melts into liquid ink when reheated. After the above-mentioned temperature-low temperature-room temperature change, the physical and chemical properties of the ink will change, which determines the performance of the ink. Freeze the ink sample in a high and low temperature test chamber, take it out and place it at room temperature and measure its technical indicators such as surface tension and viscosity, compare it with the temperature before freeze-thaw treatment, calculate its change rate, and the freeze-thaw stability of the ink can be determined.

Storage stability test method
QB/T2730.1-2013
According to the Van't Hoff rule: for every 10°C increase in temperature, the chemical reaction rate will increase to twice the original rate. This rule can be used to deduce the storage stability of the ink. Place the ink sample in a high and low temperature test chamber at (60±2)°C, take it out after a certain period of time, and measure its surface tension and viscosity after placing it at room temperature, compare it with that before treatment, and calculate its rate of change.

Test Method for UV Resistance of Prints
The short wavelength and high energy of ultraviolet light are the main factors causing the color density attenuation (fading) of printed samples. Testing the change of the print color density under ultraviolet light can quickly measure the UV resistance of inkjet printing inks. C.2 Tools and Materials

C.2.5 UV lamp: wavelength 254nm, power 30W, lamp length 850mm. C.3 Inspection steps
Use the printer's default settings to print a standard print (100% inkjet monochrome) on inkjet printing paper, use a reflective color densitometer to measure the color density value of each color block in the print block, then place it in a UV light test box with a distance between the light source and the print (150±10) mm, and irradiate for 1.5 hours. Test the color density of the print after UV irradiation, and calculate the attenuation rate of the print before and after UV irradiation according to formula (C.1): D-Dx100%

Test Method for Interpenetration of Prints
QB/T2730.1-2013
The penetration of one color into another color in the inkjet printing ink print is due to the infiltration of the water-based ink into the printing medium during the drying process. With this slight infiltration, there is a slight diffusion of the print color (i.e., interpenetration), which will stop after the ink dries. Its size can be observed and measured with a magnifying glass after the print dries. D.2 Instruments and Materials
Desktop inkjet printer.
D.2.2 Inkjet printing photo paper.
D.2.3 Scale magnifying glass: magnification of 10 times or more. D.3 Test steps
Use the default settings of a desktop inkjet printer to print a standard sample (with two adjacent color strips) on inkjet printing paper. After leaving it for 24 hours, observe it with a 10x magnifying glass. Take the distance from the three points in the field of view where one color ink penetrates the longest to the other color ink and the junction, record them as hl, hz and h3 respectively, and calculate their arithmetic mean according to formula (D.1) to be the ink penetration distance. h+h,+h
Where:
Ink penetration distance, unit is millimeter (mm). (D.1)
