Introduction to main applications of colorimeter

Colorimeter is also called portable colorimeter, color analyzer and chroma meter. The colorimeter is a simple color deviation testing instrument, that is, to make a filter that simulates the spectral characteristics equivalent to the color sensitivity of the human eye, and use it to measure the light of the sample plate. The key is to design the spectral sensitivity characteristics of this photosensitive device, and can measure and display the excellent difference through the computer software under a certain light source. It is a conventional instrument for scientific research and production, as well as a high-tech product integrating colorimetry, modern optoelectronics and computer science.

Main applications of colorimeter:
1. Product quality of color control
In order to control the color change of the product within a certain acceptable range, the production line must use a color change instrument to detect the color quality to monitor the color change of the product. Within the acceptable range, the production process should be adjusted to ensure the color quality of the product.

2. Color matching, painting, printing ink, etc.
When receiving the customer’s standard sample, the company shall assign colors according to the standard sample. In this process, the low sample should be repeated. When there is no instrument to measure the color difference between the standard sample and the sample, the color difference between the evaluation sample and the standard sample basically depends on the human eye. Due to the subjective factors of human eyes, there are some problems, such as. Long calibration cycle, high calibration cost, low color accuracy, and difficult color difference data.

Croatia deviation measurement can quickly measure the color difference between standard samples and samples, provide accurate quantitative data, fast and comfortable, and reduce the uncertainty of human eye observation. The color deviation between the sample and the standard sample can be displayed in the measured data of the color difference meter. Therefore, the color formula can be corrected according to the measured data of the colorimeter to shorten the correction period.

3. Color transfer
The international and domestic color is based on the ideal black and white board, not the instrument. Therefore, when customers hear about color cards or standard samples, they can use a color difference instrument to carry out color matching and color quality control, so as to accurately realize color reproduction and ensure correct color transmission.

Precautions during the use of colorimeter:
1. A customer provided a set of color coordinates to the manufacturer, but no standard sample was provided. In this case, it must be clear which color space the color coordinates provided by the customer were measured in, as well as the lighting conditions and the type of light source. The measured values vary greatly in different color coordinate spaces and are not comparable; In the same color space, the chromaticity coordinates vary greatly with different lighting conditions, but the chromaticity difference is relatively small. In this case, the customer should provide the standard sample, use the standard sample to communicate with the user, use the standard sample as the reference, and control the color difference;

2. It is necessary to determine the color coordinate space of the current instrument according to the user’s color coordinate space. All instruments are adjusted using the standard white board as the benchmark. When the instrument is used for a period of time, it is necessary to recalibrate the instrument with the standard white board attached to it to achieve the highest measurement accuracy;

3. The difference between the two measurements is large
①. Dirty objects entering the measuring port will cause inaccurate measurement and seriously affect the measurement results;
②. Check whether the battery consumption is too low (less than 20%), replace it with a new dry battery or use DC power supply.
③. Check whether the instruments and test objects are stable during the measurement, and whether the contact between the measuring port and the measuring surface is tight and good;
④. Check whether the measured object is too thin to leak light
⑤. Check whether the measured part is mixed

How to select a suitable colorimeter:
1. Budget, according to the actual budget of oneself or the enterprise, is to buy imported or domestic products. If you think you have a sufficient budget and are interested in imported products, you can consider importing. After all, it is not your fault to have more money! If you are interested in the domestic color difference instrument, you can also know more about it. After so many years of development, the performance of the domestic color difference instrument can be completely comparable to that of the imported color difference instrument. What’s more, the price is much cheaper than that of the imported color difference instrument, and the after-sales time of the imported color difference instrument is long and the cost is high. This is also the reason why more and more enterprises choose the domestic color difference instrument in recent years.

2. You need to know which color difference instrument is suitable for your industry. Each industry has different requirements for color difference accuracy, that is, △ Eab. If △ Eab is between 0-1, then you must choose the instrument with higher accuracy; These are generally rubber and plastic, paint and paint industries; If you do not need high accuracy, you can also choose a general color difference instrument.

3. You need to know the shape of your product. At present, the test aperture of the general color difference instrument is 4mm or 8mm; If your product is curved or very small in size, you need to consider the test aperture; Of course, it can also be customized, such as:
Large aperture (LAV): 2.54 cm (1 inch)
Medium aperture (MAV): 1.5 cm (0.6 in)
Small aperture (SAV): 0.75 cm x 1.0 cm (0.3 in x 0.4 in)
VSAV: 0.3 cm x 0.8 cm (0.12 in x 0.31 in)

4. Whether there is national metrological certification. This instrument is a metrological instrument. You should know whether the product can meet the national metrological requirements, otherwise there will be a dispute, and your data cannot be referred to. In general, for a colorimeter that is worth buying, there are many factors worth considering besides the above main factors.

Portable Colorimeter/Chroma Meter is an innovation color measuring tool with powerful configuration to make color measurement easier and more professional; It support Bluetooth to connect with Android and ISO devices, Portable Colorimeter/Chroma Meter will take you into a new world of color management; It can be widely used to measure color value, color difference value and find similar color from color cards for printing industry, paint industry, textile industry, etc.
