Installation and use of color quality management software for spectrophotometer

The spectrophotometer has high accuracy and uses the setting of the pre-positioning board, which eliminates the need to use the standard blackboard and whiteboard in the calibration process of the traditional colorimeter and colorimeter. The built-in software has powerful functions, including all necessary color equations, standard light sources suitable for different tasks, and a large number of indicators for specific industries and applications.

Design principle:

The spectrophotometer is designed according to the principle of spectrophotometer. The spectrophotometer has high accuracy and increasing versatility. The spectrophotometer can simultaneously measure SCI (a measurement method including specular reflection. For this reason, it reduces the influence of sample surface, especially suitable for color quality monitoring and computer color matching) and SCE (a measurement method excluding specular reflection. The results of this type of measurement are similar to those observed by the naked eye). Because it can measure the reflectivity at each wavelength, it is suitable for complex color analysis, and of course it is relatively expensive.

Because of the interference of specular reflection, it is very troublesome to detect the color of many metallic paints. It is impossible to accurately and reliably determine the color information of products using traditional visual method. For this reason, scientists have made continuous efforts to develop a color detection instrument suitable for specular reflection, spectrophotometer. This instrument provides two color detection modes, SCE and SCI, for color detection, and provides a perfect tool for correct measurement of the essential color of objects under specular reflection.

Whether the surface of an object is specular or diffuse depends on the indicated gloss of the product. Specular light with high glossiness is more reflective, and diffuse light with low glossiness is more reflective. However, the sum of the specular light height and the diffuse light height of the object remains unchanged. Therefore, the design of the spectrophotometer has grasped this point and started to develop two modes: SCI and SCE. SCI (Specular Component Included) refers to the measurement color mode of specular reflection light, and SCE (Specular Component Excluded) refers to the measurement color mode of excluding specular reflection light.

In the SCE mode of the spectrophotometer, the measurement is to measure the diffuse reflected light by excluding the specular reflection. The color data value measured in this mode is equivalent to the color observed by visual observation. When using SCI mode, both specular reflection and diffuse reflection exist in the measurement process, so the measured color result belongs to the objective color of the object, which is very important for the manufacturers who have high requirements for color detection. Completely copying the product will not cause the deviation of the copy result because of ignoring the specular reflection.

I. Precautions for installation of color quality management software Color QC of spectrophotometer:

1. Load the CD of Color QC software into the computer
2. Open “My Computer”, find Color QC in the driver, and click to install; After installation, the interface shown below will be displayed;
3. Please refer to the steps in the manual for specific installation details.
Select USB communication through the UP and DOWN keys, and confirm with the enter key

II. Connect communication port

1. First, prepare the spectrophotometer, data cable and computer
2. Connect the spectrophotometer and computer with USB cable;
3. Open the spectrophotometer, click “Cancel” to enter the interface, listen to “UP” and “DOWN”, select “USB communication” and click “enter” to connect;
4. The display of USB connected (as shown in the figure) indicates that the connection is successful.

III. First use of color quality management software Color QC：

1. Check that “USB communication” is connected successfully;
2. Perform black and white calibration;
3. Set the tolerance Δ E is different. Generally, if the requirement is within 1, then the sample with the result within 1 is qualified; The higher requirements are generally set within 0.5, which can be set according to different requirements
4. Collect standard samples and samples. As shown in the figure, you can name and save the name of the standard sample and sample independently;
5. The measured sample data can be saved for future use. Click the data to be saved and then click “++Library” to save it;
6. The established database is as follows

VI. What should I do if the “USB communication” of the spectrophotometer is “unable to connect”?

1. When the spectrophotometer and the computer are connected abnormally, the phenomenon of “unable to connect” appears. At this time, you should check whether the USB cable is well connected with the spectrophotometer and the computer. You can plug and unplug the USB cable again to check whether the contact is good, and exit the “USB communication” interface of the spectrophotometer and re-enter the “USB communication” interface.

2. Under the condition that the USB cable is well connected with the spectrophotometer and the computer, restart the spectrophotometer, enter the main menu of the spectrophotometer, select “USB communication”, press the “enter” key on the spectrophotometer, and let the spectrophotometer enter the communication state.

3. Close the Color QC software and reopen the Color QC software.
4. Replace the USB cable or replace a USB oral test on the PC.

The above are the operation methods and problems that may occur during the use of color QC, the spectrophotometer software. I hope to solve some problems for you!
