The viscosity of ink is one of the key factors affecting the quality of printed matter. If the viscosity of the ink is too high or too low, it will affect the physical properties of the ink such as fluidity, dispersion, and adhesion, thereby affecting the quality of printed matter. Here are some important reasons for measuring ink viscosity:
Quality control: By measuring the viscosity of the ink, the stability and consistency of the ink during the production process can be determined to ensure that the ink quality of each batch produced is consistent.
Processing control: By measuring the viscosity of the ink, the flow properties and processability of the ink during the printing process can be determined to ensure that the ink can provide the required processing properties.
Color control: By measuring the viscosity of the ink, the color, transparency and texture of the ink can be controlled to ensure that the color effect of the printed matter meets the requirements.
Material comparison: By comparing the viscosity of different batches or different types of inks, it is possible to determine which ink is more suitable for a specific application to improve the quality and efficiency of printed matter.
Application improvement: By measuring the viscosity of the ink, the effect of inks with different viscosities under different printing conditions can be explored to improve and optimize the printing process.
Measuring ink viscosity is one of the key steps to ensure the quality of ink prints and production efficiency, which is very important for the printing industry. Rotational viscometers are widely used in ink viscosity testing, which can help manufacturers control ink viscosity and fluidity to ensure product quality and stability.
The following are the basic steps of Rotational Viscometer in ink viscosity detection:
Sample preparation: Stir the ink sample to be tested evenly and bring it to the required temperature.
Instrument preparation: turn on the Rotational Viscometer, adjust the temperature and rotation speed, and calibrate the zero point.
Sample test: inject the sample into the viscometer, pay attention to avoid the generation of air bubbles, record the reading, and record the time and temperature. Repeat the test three times and take the average value.
Data processing: Calculate the viscosity value of the sample according to the readings obtained from the experiment, and perform data analysis.
NBCHAO reminds you: when testing the ink viscosity, you should pay attention to the temperature and stirring time of the sample to ensure the uniformity and stability of the sample. In addition, different types of inks, such as solvent-based, water-based, etc., may have different measurement conditions and data processing methods, which need to be adjusted according to the actual situation. At the same time, when using a Rotational Viscometer for ink testing, attention should also be paid to the maintenance and maintenance of the instrument to ensure the accuracy and stability of the test results.
