FAQs About Light Booth
Record the L*a*b values of the sample and the reference with a calibrated spectrophotometer or colorimeter. Compute the difference in the color by use of ΔE. The lower the Delta E, the more accurate the result. The difference in energy, ΔE < 1, is generally assumed to be invisible to the eye.
At most of time, we have Spectrophotometer stock in the factory. Generally it is 1-3 working days after the payment confirmed. After shipped, we will email you the tracking number. You can check the shipping status of your order on the website. If you are in urgent need, we can consider making special arrangement for you.
Take L*a*b* readings of two samples using a colorimeter or spectrophotometer and calculate color difference using the 3 formula (Delta E). The difference in 0 is the reported Delta-E, which shows how visible the change is, whereas the thresholds define the acceptability as per the application requirements.
a. Right click "! USB Device" or "! SCI USB2Serial (COM6)", "Update Driver" -> "Install from a list or specific location (Advanced)" -> "Next" ->"Include this location in the search" -> "Browse", specify USB driver file path "CQCS3USB_Driver", click "Next". Then it will install successfully.
b.Detailed installation information please refers to "2.2 Installing USB Driver" in Color Quality Management System User Manual.doc.
The various colors can be measured by the way a surface reflects, absorbs, or transmits light at different wavelengths. These responses may be measured using instruments such as colorimeters or spectrophotometers to give numeric values in a standardized color space such as L *a*b*.
D/8°and 45°/0°are two kinds of illumination geometry with different optical geometry design. D/8°illumination geometry is more widely used for the color comparison and measurement of high-gloss materials; 45°/0°illumination geometry is mainly used in printing and packaging industries.
