When it comes to color matching, we are used to call red, yellow and blue dyes as three primary colors. If we know the same amount of three primary colors, we can get black. If we mix the primary colors with the primary colors, we can get two colors, that is, red plus yellow produces orange, red plus blue produces purple, blue plus yellow produces green. The addition of any secondary color with another corresponding primary color can also produce black, and the addition of any secondary color with another secondary color can produce three colors, which is the basic principle of the three primary colors that we are all familiar with. To be an excellent toner, we should not only understand the principle of color matching and the characteristics of color gum, but also understand the changes of color gum, such as color mouth, color silk, color system, etc. After mastering these basic knowledge and long-term experience accumulation, we can gradually produce qualified samples. Let's give you an example to illustrate the steps of color matching. First, after we get a color card, we need to quickly distinguish the basic tone of the color. We need to find the right color system and then distinguish its proportion. This is a bit difficult. We can distinguish it by looking at its transmittance when we shine in the sun or in the light. With these basic preparations, we can take ontology for debugging. Usually we take the ontology 1KG as the benchmark and debug the color masterbatches weighing the estimators. Then we can add more color masterbatches at the first time and gradually increase according to the quantities. So we don't pursue the unification of color and light tightly, and we also need to consider the economic benefits. The same color and different toners have different recipes. Everyone knows that the body color of silica gel is transparent. (For example, we need to mix one (orange) with 1% Red + 0.5% yellow to mark it: We can also use 2% Red + 1% white. This is to increase the proportion of colour glue and then use white to reduce it.) This simple example can be seen its so-called economic benefits, so that we add 35G color masterbatch in 1KG raw materials when we mass production, this is the cost increase. Here are some tips for color matching 1. Basic color change: A red with blue light and a blue with green light are impossible to produce pure purple. A red with yellow light and a yellow with red light add up to get a pure orange. Through these two examples, we can see how important the influence of brilliant light on toner is. In actual production, the influence of color light is often the biggest factor for toner. In general, orange is more red and yellow, green is more blue than yellow, purple is more blue than red. (Red) Blue + (Yellow) Red = Purple (yellow) blue + (blue) yellow = pure green (red) Yellow + (yellow) red = pure orange 2. Mutual fading applications, the so-called fading is the use of two dyes to subtract each other characteristics, such as a blue with red light, if the red light too heavy sample does not meet the requirements, you can add less.
