Lastest company news about The difference between SCI and SCE 2024/02/23
The difference between SCI and SCE
SCI refers to the inclusion of specular reflected light mode, generally used for those who study the properties of the color itself without concern for the color attached to the surface gloss of the sample manufacturers, such as paint coating factories. SCE refers to the method that does not contain specular reflected light, which is generally suitable for those samples that are directly observed and require measurement results to be very close to the visual view, such as home appliance housings. In the SCE measurement mode, specular reflected light is excluded and only diffuse light is measured. The value thus measured is comparable to the color of the object as it appears to the observer. When SCI mode is used, specular reflected light is included in the measurement along with diffuse light. The value measured in this way is the overall objective color of the object, and has nothing to do with the surface conditions of the object. These criteria must be taken into account when we choose an instrument. Some instruments can also measure values in both SCE and SCI modes. Even if the object is made of the same material, the color will look different due to the difference in surface gloss. For example, when the surface of a smooth, bright blue sample is rubbed with sandpaper, why does the blue appear a little dimmer? When the elastic ball is thrown at the wall and bounces back, the Angle is the same. In the same way, because the light source produces light that is reflected back from the same Angle in different directions, we call it mirror reflected light, because the light is like being reflected back by the mirror. Light that is not reflected by specular reflection but scattered in all directions is called diffuse light. The sum of specular and diffuse light is what we call reflected light. On smooth, bright surfaces, specular light is stronger and diffuse light is weaker. On rough surfaces with low gloss, the opposite is true. When we look at a blue plastic object with a smooth surface at a specular reflection Angle, the object appears less blue because the specular reflection from the light source is added to the color of the object. Generally speaking, people ignore the reflection of specular light when looking at the color of objects. Therefore, when measuring such samples, in order to make the data look like the object, it is necessary to exclude specular reflected light and measure only diffuse light. The color of an object is different because of the amount of light reflected by the mirror we observe. We already know that because people only look at diffuse light, when the surface conditions of the object change, the color will appear different. However, since the material of the object itself is the same, the color of the object should not change. How can we get the color of the material itself? The content of specular reflected light and diffuse light is determined according to the surface of the object. But under certain conditions of material and color, the total amount of the two kinds of light is always the same. Thus, when the smooth blue plastic sample is roughened, the specular reflected light content decreases and the diffuse light content increases. This is why we need to measure the total reflected light (the sum of specular and diffuse light).

Color management of color spectrum color difference meter in hardware products
Hardware surface color is a variety of, but also through a variety of means of surface color treatment. Not only for the light color is beautiful, more is to achieve surface oxidation protection. The control of the color of the hardware surface has become an essential part of the production process of hardware products. Generally through some special methods to the hardware surface color deployment, such as spray painting processing, electroplating, surface polishing, corrosion processing, etc., are the deployment of hardware surface color. Through painting processing, you can avoid rust on the surface of the hardware, such as daily necessities, electrical enclosures, crafts, etc., need to be treated with surface color. Electroplating is also the most common metal processing of a processing technology, through modern technology to hardware surface plating, to ensure that products for a long time under the use of mildew does not occur embroidery, electroplating processing common screws, stamping parts, battery pieces, car parts, small accessories and so on. Surface polishing processing is generally more commonly used in daily necessities, through the surface burr treatment of hardware products, the sharp parts of the corners are thrown into a smooth surface, so that it will not cause harm to the human body in the process of use. In addition, the metal die-casting (die-casting is divided into cold pressing and hot pressing), stamping, sand, mold casting and other processes will also change the color of the hardware. Because the surface of hardware products is relatively rough, and some even have lines, therefore, in the color difference control, it is necessary to use a large-caliber color detection instrument to detect it, so as to detect the object color difference surface more evenly. The color difference detection of hardware materials can better judge the difference between materials, test samples and standard samples, remove unqualified products, and improve product quality. Due to the particularity of the hardware product itself, the precision requirement of color difference detection is not very high, and the color detection can be realized by using a general large-caliber color difference meter.

When encountering irregular samples, how to measure their surface gloss?
Luster belongs to the visual perception of people on the one hand, the buyer in considering the value of the product, the luster of the product and the color have the same important status. Objects with a high gloss look like they can glow, and are not metal but have a metallic luster. The gloss of the surface of the object will be affected by many factors, such as: the smoothness after polishing, the thickness of the paint used, the brand, and the substrate of the object. Manufacturers will continue to introduce new designs according to the needs of buyers, such as: highly reflective car panels, high-end magazine covers, fashionable furniture in satin black and other products with gloss treatment to reach a greater extent to attract buyers' attention. Manufacturers in the production, to ensure that the gloss of the product is strictly carried out according to the standard, which requires the gloss meter to be used as a detection tool. The application scenario of gloss meter can make incoming material inspection, quality sampling inspection in production, and factory inspection. Ordinary gloss meter is only suitable for measuring flat products such as paper and tiles, but small objects or curved products such as buttons, thermos cups, wrenches are not suitable for measuring with ordinary gloss meter, which requires the use of microporous gloss meter to measure special irregular shape products. The microporous gloss meter CS-300S (measuring aperture: 2*3mm) can solve the gloss measurement of irregular samples, and is suitable for measuring the surface gloss of complex shapes on the measured surface such as mechanical parts, jewelry, crafts, plastic pipes, hardware decoration, test samples, etc. (Same applies to flat gloss measurement).

What is the difference between light reflectance and gloss?
Light reflectivity and gloss are two different concepts, there are many different differences between them, but there is a certain connection, in general, the higher the light reflectivity of the object the higher the gloss. When light is emitted from a medium to the interface of another medium, a part of the light returns to the original medium, so that the propagation direction of light has changed, this phenomenon is called light reflection, the ratio of reflected light and incident light, is the reflectivity. Gloss refers to the ability of the surface of the object to reflect the light from a certain Angle, and the main factors affecting gloss are the roughness of the surface of the object and the molecular structure of the object itself. We know that the reflectivity of different objects is also different, the reflectivity mainly depends on the nature of the object itself and the situation of the surface, as well as the wavelength and incidence Angle of the incident inductance wave, the range of reflectivity is less than or equal to 1, the use of reflectivity can judge the nature of the object. The reflectance formula is that when the beam is close to normal incidence (the Angle of incidence θ is about 0), the reflectance formula is R=(n1-n2)^2/ (n1 +n2)^2. Where n1 and n2 are the true refractive indices (that is, refractive indices relative to vacuum) of the two media respectively. Refractive index refers to the phenomenon that the Angle of light changes when it enters different media, and is characterized by sinθ1/sinθ2. θ1 and θ2 are the angles of incidence and refraction, respectively, that is, the Angle between the light and the normal. In general, the reflectivity of light on the critical plane is only related to the physical properties of the medium, the wavelength of the light, and the Angle of incidence. In the case of continuous change of refractive index of the medium, the reflectivity is also related to the thickness of the medium because of the interference effect of reflected light at different interfaces. Thus, we can design a coating with a specific thickness and a specific refractive index to obtain a coating with a large reflectivity or transmittance to a specific wavelength of light. The reflectivity is related to the refractive index of the two media, the incident Angle, the wavelength of the light, etc. The greater the incidence Angle, the stronger the reflected light. In the case of a certain medium and wavelength, when the incidence Angle is greater than a certain (critical) Angle, the reflected light is equal to the incident light, which is called total reflection. Fiber optic transmission takes advantage of this phenomenon. The gloss unit (GU) scale is linear, and each Angle of incidence has a different measuring range. 0-2000GU (20°), 0-1000GU (60°), 0-160GU (85°). % Reflectance compares the light energy sent and received with a gloss meter and expresses the full measured range of Angle incidence of the value in percentage, and the value is displayed as a percentage with respect to the selected Angle of incidence. Therefore, the light reflectance and gloss are not only different in the concept of light reflectance and gloss, but also in the calculation method is different, light reflectance is a percentage value, and gloss has GU units. The optical reflectance of the human eye can not be subjective and objective effective judgment, and the gloss can be judged by the human eye.

Inverted measurement -- The function of color spectrum technology desktop spectrophotometer
In our past cognition, the desktop spectrophotometer generally uses side measurement or upward measurement to measure non-transparent substances, and these two measurement modes also cover the color detection of all non-transparent substances.                                                                Side measurement                                         Upward measurement   So why is there a pattern of handstand measurements? This needs to start with the structure of the desktop spectrophotometer, a very important part of the instrument measurement is the integrating sphere, the integrating sphere of the desktop spectrophotometer is 152mm in diameter, and the interior is coated with a layer of white diffuse reflection material, the diffuse reflection coefficient of the diffuse reflection material is close to 1, and the sphere is close to an ideal sphere. In this way, after many reflections in the integrating sphere, the lighting source will form a uniform illuminance on the inner wall, which improves the measurement accuracy of the desktop spectrophotometer.                                                               Reflection test principle                                    Integrating sphere   To sum up, it is very important to ensure the cleanliness of the integrating ball. When the inside of the integrating sphere is polluted, the accuracy of the measurement data is bound to be affected. Especially like the textile and fabric industry, in the cutting process, there will be a lot of raw edges and fabric debris, if the side measurement or upward measurement is used, the fabric debris is very easy to fall into the integrating ball, and it is easy to stick to the inner wall of the integrating ball. Over time, the integrating sphere of the instrument is scrapped, which not only shortens the service life of the instrument, but more importantly, affects the accuracy of the instrument measurement. Fabric frills, scraps   For this kind of products, color spectrum technology proposed the inverted measurement mode, install a vertical bracket on the desktop spectrophotometer, and put the test port corresponding to the integrating ball down, no matter how the measurement, the fabric debris will not fall into the integrating ball, to ensure the cleanliness of the instrument. Vertical support back                          Vertical support front   Customized vertical stand for desktop spectrophotometer CS-820N/821N/826, to ensure the stability of the instrument upside down, movable damping handle, to ensure that the test port does not leak light during measurement, so that the instrument accurately evaluates the color of the product. Test port detail diagram                      Handstand measurement   In addition to the textile fabric industry, powder can also be measured in this way, welcome to consult us!

Luster basic knowledge principle and testing instrument
Gloss test principle Glossometer mainly measures the glossiness/reflectance of the surface of an object. The gloss is calculated by reflecting the incidence Angle of the light source back to the corresponding Angle receiver. The gloss unit is GU Generally divided into: single Angle: 60° measurement Multi-angle: 20°, 60°, 85° three-angle measurement What is light spot: Measuring the area of light emitted during the hole test, not measuring the hole size.   Roughness and gloss misunderstanding The difference between roughness and gloss   Surface roughness refers to the small spacing of the machined surface and the unevenness of the small peaks and valleys. The distance (wave distance) between the two peaks or two troughs is very small (below 1mm), and it belongs to the microscopic geometry error. The smaller the surface roughness, the smoother the surface.   Surface roughness and surface finish are the same concept, and surface finish is another name for surface roughness. There are corresponding comparison tables for surface finish and surface roughness.   Surface roughness meter Surface roughness measurement using roughness meter (size detection instrument) detection; The surface glossiness is the strength of the diffuse reflection of the object surface to the light, which can be measured by the surface glossiness. Surface gloss To the naked eye, the surface diffuse reflection is strong, it is closer to the mirror effect, then the gloss is high, on the contrary, the surface diffuse reflection is weak, then the gloss is low, so the gloss is also called mirror gloss.   Handheld gloss meter                                                   CS-300 single Angle gloss meter                                                            CS-300S microporous gloss meter                                                Test diameter 2*3mm                                                                                Test diameter 2*3mm   Gloss units and national standards   What is the unit of gloss?

Lastest company news about Why choose a multi angle spectrophotometer 2023/12/29
Why choose a multi angle spectrophotometer
Not every product looks so uniform and flat. Products with irregular shapes, as well as reflective and fluorescent products, also require color detection and control. This is a multi angle colorimeter that can perform more complex measurements as needed. In fact, multi angle color measurement colorimeters are mostly developed for color control of metal paint. We know that many products in industry are metal paint colors, and measuring colors with ordinary colorimeters is not accurate because of their high reflectivity. However, products such as automobiles, household appliances, and hardware have very high color requirements, so the development of multi angle color measurement colorimeters is also beyond doubt.   Many standards objectively describe the color measurement of multi angle colorimeters as the color measurement of the fastest flashing topcoat. Generally, the results of data analysis show that if you want to measure the color of metallic paint well, at least 3 observation angles are needed, and 5 are generally the best. To understand the color measurement of metallic paint, we need to be familiar with a keyword: adverse reflection angle. Adverse reflection angle refers to the observation angle measured from the mirror reflection direction of the light source in the same horizontal plane.   Usually, the formula for calculating color difference using the colorimeter we use is represented by data △ L *, a *, b *, or L *, C *, h *, with △ representing the total color difference. However, this is within the allowable range of color data differences. For the angles of adverse reflection angle and brightness/dark transition angle, they have already exceeded this range. Therefore, using this method to detect and analyze obvious results is unreliable. Therefore, scientists are allowed to develop multi angle color difference meters based on industrial needs and measurement ranges. This colorimeter brings groundbreaking benefits to products such as appliances and cars that have very strict color requirements and are difficult to measure.   The purpose of developing a multi angle colorimeter is to capture the complete trajectory of pigment color changes caused by light interference. Moreover, the entire measurement program is reliably used in industrial use, and the measurement is convenient, fast, and suitable for color detection and control in large-scale production. Therefore, the widespread use of multi angle color difference meters is reasonable and inevitable. It does not know how many manufacturers meet the needs of metal color detection.

Today, we'll compare how portable and desktop colorimeters perform in common color measurement situations, so you can decide which one is best for your needs.   Overall comparison: desktop VS portable   Desktop devices are known to be more accurate and consistent than portable devices. Benchtop devices are often preferred when using strict tolerances or when formulating color specifications. Benchtop equipment is used for specification, formulation, and quality control by color professionals who must match the colors of a brand or its manufactured components at the time of final assembly. At the same time, the portable device is suitable for spot checking quality in the laboratory, or can be carried around to measure color anytime and anywhere for design inspiration.   Application comparison: How to use a desktop or portable spectrophotometer   1 -- Measure the transmission If you want to measure liquids like orange juice, laundry detergent, or shampoo, desktop devices offer something that portable devices can't - transmission measurement. This is computed through the measured object. You can also measure the transparency and haze of plastic and packaging (such as 2-liter bottles and clear blister packaging) to ensure that the opacity is accurate.   2 -- Make the color paste Desktop devices are the first choice for formulating color recipes. It is also widely used to prepare different degrees of opacity in plastics, to prepare liquid dyes for textiles and color pastes for paints.   3 - Set standards Setting standards is a very important step in the color program. If you set the wrong color, how can you expect it to be accurate in production? When precise accuracy is required, benchtop instruments are often the first choice for setting color standards because they ensure repeatability and reproducibility of color accuracy.   4 - As part of a group of instruments If you work with color management across regions, or use different instruments in your lab, you need to consider repeatability and consistency between each instrument. Even though measurements from the same instrument may vary slightly from case to case, the range of differences can be magnified when you're dealing with multiple instruments.   The benchtop instrument is designed to achieve accurate color repeatability, making the correlation between different devices higher. Although our portable devices are also excellent, there can be a 0.13 difference in portable devices at the high end of the market.   5 - Take it with you in the lab Without a doubt, portable equipment is the best choice outside the laboratory. They are very useful for production spot checks to ensure color consistency throughout the run. It can also be used in the field to obtain color information used in the design or to perform quality checks at the supplier's site. Many devices provide Bluetooth connections that allow instant color analysis, while others plug into the main computer to download data.   6 - For quality control While many people believe that portable spectrophotometers are suitable for quality control because of their portability, there are other things to consider.   First, measure the size of the point. In an ideal world, our 6 mm single point and 25 mm single point measurements would be identical. However, if the sample has small defects, such as tiny scratches, lint, dirt, or dust, this defect will occupy a large part of the small measurement area, returning erroneous measurements. Texture and orientation differences and sample imperfections also affect the results. Benchtop devices tend to measure larger areas and can average out defects better.   Second, the backing. Unless the sample is completely opaque, anything behind the sample at the time of measurement may reflect and alter the result. The desktop comes with a built-in backing, so it does not have to be considered. When using portable devices, the portability is excellent, but you also need to use a backing to get consistent results.   7 -- Measure fluorescent whitening agent One final consideration: if you're dealing with fluorescent brighteners, you'll need to use UV-calibrated instruments for consistency. This is common for desktop devices, but some portable devices can also perform UV calibration.   So, which one do you choose?
