Conductive plastic color matching is an important part of coloring

The first choice for color matching is to design the initial formula, and then adjust the initial formula to make it suitable for large-scale production and ensure the uniformity of the color of plastic products. According to the requirements of the overall design of plastic products, samples similar to the standard color samples were determined as reference materials.
The selection of the reference material is directly related to the coloring effect. In order to find a better coloring reference, we should accumulate more and more colored plastic color plates or plastic color plates as a reference. At the same time, we should also prepare our own color selection experience and lessons for reference.
Abstract According to the difference between the standard color and the reference color, the formula of the reference color was modified, and a preliminary formula was prepared.
In the absence of reference, the color, color and brightness of conductive plastic materials (samples) should be carefully observed and analyzed to determine the color properties and determine whether the color is transparent or opaque, as well as other special pigments (such as fluorescent pigments, metallic pigments, etc. Etc.) then according to Munsell. The color of the color system. Or design the required color according to the calibration principle of the Munsell color system and draw the initial formula.
The adjustment formula was physically dyed according to the preliminary formula, and was colored with standard color samples and reference materials, and the coloring formula was further adjusted. An actual sample was then prepared according to the adjusted formula.
The formula is repeatedly adjusted until the actual color is the same as the standard color sample or the closest standard color sample is satisfied. Finally, the coloring formula was determined. However, the colors chosen are often different from the actual production of plastic products, causing these differences to a large extent due to color weighing errors.
