With the development of science and technology, the colorimeter, as a commonly used color measuring instrument, has been widely used in various fields. Among them, in the printing industry, colorimeters are often used to measure the hiding power of inks, so as to help printing companies better control the quality of printing. This article will introduce the methods and precautions for measuring the hiding power of ink by the color meter.
First, the method of measuring the hiding power of ink by the color meter.
1.Preparation.
Before performing a colorimeter to measure ink opacity, the following tools and materials need to be prepared: a colorimeter, a standard whiteboard, an ink sample, a standard light source box, etc.
2.Measurement steps.
1) Place the standard whiteboard in the standard light source box to ensure that the light source is stable and uniform.
2) Place the colorimeter in a standard light source box, making sure the lens is aligned with the standard whiteboard.
3) Turn on the colorimeter and select the appropriate measurement mode and parameters, such as C, L, A, B, etc.
4) Apply the ink sample to a standard whiteboard, making sure that the application is even and free of bubbles.
5) Wait for the ink to dry, and then use the colorimeter to measure the whiteboard again.
3.Data processing.
By comparing the measurement data before and after application, the hiding power of the ink can be determined. Generally speaking, the stronger the opacity, the stronger the ink's ability to cover the whiteboard.
2. Precautions.
1.When using a colorimeter to measure the hiding power of ink, it is important to ensure that the light source is stable and homogeneous, so as to avoid affecting the measurement results due to fluctuations in the light source.
2.When applying ink, make sure that the ink is applied evenly and without air bubbles, otherwise the measurement result will be affected.
3.When waiting for the ink to dry, you should ensure that the ambient temperature and humidity are suitable to avoid uneven drying of the ink due to environmental factors.
4.When comparing the measurement data before and after application, it should be ensured that the measurement parameters and patterns are consistent to ensure the accuracy of the measurement results.
In conclusion, measuring ink hiding with a colorimeter is an easy and accurate method. In the printing industry, by using a colorimeter to measure the hiding power of ink, the printing quality can be better controlled, and the quality and market competitiveness of the product can be improved.
