  Computer color matching system includes spectrophotometer and color matching software. Spectrophotometer is mainly for color measurement and transferring the data into the color matching software. Color matching software will analysis the test result and calculates the best recipes/formula for color matching.   Advantages of Color Matching Software comparing with chemist   1. Simple operation and repaid result : From sample measurement to get recipe, only need about 5-10 minutes. 2. Software can provide different kinds of recipes for the user. The user can choose according to the raw materials cost or raw materials left in warehouse. 3. Software cost is cheaper than hiring more people. One professional chemist with software will be enough for color matching. 4. Recipe get from color matching software is high accuracy and increasing the working efficiency of chemist 5. The color matching quantity is controllable, waste material can also be used for color matching which saves cost.   How to do color matching?   Step 1. We need upload the pigment information and basic material into the software.     Step 2. Set the base information, measurement condition, color layer thickness, etc. Then measure the sample with spectrophotometer.   Sample   Color Matching Software   Step 3. After measurement, press “calculation” on software, then software will start to calculate the formula. Software will provide 3 formulas for the user. It will tell what kind of pigment and how much pigment should be used for color matching.   We make the samples according to the recipe and compare the color different value Delta E*ab with the target sample. The color different is very small. The following picture is the result. (The smaller the color difference value is, the smaller the color difference is.) According to the result, we can see sample made according to formula 3 is very close to the target. Delta E*ab 0.17 is very small color difference.     Name Color Difference Value Comparing with Target Formula 1 Delta E*ab 1.92 Formula 2 Delta E*ab 0.92 Formula 3 Delta E*ab 0.17

Labels or tags are commonly seen in our daily life. In the production process of the labels, the customer will give a sample as a target or give a pantone color number. Then they will ask the label manufacturer to make a sample. After the sample is made, the label manufacturer will compare the sample with target or pantone color number and let the customer confirm it.   After the sample is confirmed, then manufacturer will start mass production. Today, we will introduce how print colour tester CS-600C can help to check color on labels.   Measurement Condition 1. Mode: Reflectance 2. Light Source and Angle: D65/10 degree 3.

1. What is gloss meter?   Gloss is the physical quantity that is used to evaluate the reflect ability of a material's surface under a defined condition. The gloss we usually refer to is "specular gloss," so gloss meter sometimes is called "specular gloss meter” which is mainly used to evaluate the surface gloss of products. Gloss do not have unit, GU is the abbreviation of gloss unit.     2. Usage of Gloss Meter   Gloss meter is used to measure the gloss degree of the surface. The angles selected for measurements are different and the results are also different. The larger the angle, the greater the specular reflectance, the higher the gloss value is; and vice versa. Thus, the level of gloss depends not only on the surface properties of the object, but also on the measurement angle. According to the angles, gloss meter can be mainly divided into 20 ° high gloss meter, 60 ° gloss meter and 85 ° low gloss meter.     3.How to Choose Gloss Meter?   20 ° gloss meter refers standards of ISO-2813, ASTM-D523, ASTM-D2457, etc., mainly for high-gloss paint, ink, plastic, paper, glossy wax paper and casting coated paper. 60 °gloss meter refers standards of ISO-2813, ASTM-C584, ASTM-D523, DIN-6750, ASTM-D2457, etc., mainly used in the luster of the paint, ink, plastic, ceramics, marble, coated paper. 85 °gloss meter refers standards of ISO-2813, DIN-67530, ASTM-D523, etc., mainly for low-gloss paint, camouflage coating, etc.     4. How to choose the Angle of Gloss Meter?   We can start from 60 °, and if the result is between 10-90GU, then choose 60 ° angle. If the result is less than 10GU, then low gloss 85 ° is more suitable; if the result is higher than 90GU, the product is high gloss, 20 ° is more suitable.     CHNSpec CS-380 is a universal portable gloss meter with measurement range 0-1000GU. It is suitable measure both low gloss and high gloss surface. Any color and gloss measurement question, please contact us freely.

Recently, we get customer inquiry for measuring color of meat by spectrophotometer, today we will introduce how to measure and which instrument is suitable and why need to measure it.   1. Why need to measure the color of meat?   Color is one of the most important quality index for meat. The color of meat generally changes slightly with time, and consumers often associate the "appropriate" color of meat with the quality and freshness of the meat. For example: fresh tuna has a ruddy color, but this red color will decompose with the storage time, causing the color to darken. We can determine the freshness of this fish by measuring its color.     2. What are the measurement methods to measure the color of meat?   If check it by human eyes, it will take longer time and energy to get the result . And test result get by human eyes is subjective.   There is another method, color of meat can be determined by measuring the pigment content inside it, but this method will need a lot of time and chemical reagent.   Spectrophotometer will be the best measurement method. After measurement, the meat color value can be directly seen on the instrument.   3. How to measure the color of meat by spectrophotometer?     Measurement Condition   1. Mode: Reflectance 2. Light Source and Angle: D65/10 degree 3. Parameters need to Measure: color value CIE L*a*b or Hunter L*a*b. (CIE L*a*b is the most commonly used color index for measurement of meat. ) 4. Instrument: Spectrophotometer with glass sealed aperture     Test Method   1. Put the instrument directly on the chicken meat, press test then we can get the test result directly on the instrument screen.     After measurement, we can get the following test result. Sample Name L a b Chicken Meat 47.73 23.69 15.71   If any color measurement inquiry, you are welcome to contact us for more details.
