Case Study of Print Measurement - 1

After printing for 1 to 2 hours, the printer needs to recalibrate the ink to ensure that the print head is not contaminated and to maintain color consistency in the printed materials.

Case Study on Print Measurement - 2

The principle of color measurement can be divided into two types. One is to measure luminous objects, such as displays or lamps, for which we can directly use a spectrometer for color measurement. The other is non-luminous objects. The color of non-luminous objects is determined by the light source that illuminates them. This is why in the market, pork appears very fresh under pink lighting, but when you take it home and look at it under sunlight, it doesn't seem fresh. Therefore, the color of non-luminous objects is highly dependent on the light source.

So in the international context, if it is necessary to determine the color of the object being tested, such as the color of fabric, color cards, paint, or coatings, we need to determine the light source for illumination. Generally, the internationally accepted standard is the D65 light source (a white 6500K fluorescent tube simulating daylight).
