Effectively using color principles to deploy spot color inks

In disc printing, dark ink is more difficult to match with lighter inks. Inexperienced craftsmen often use more special colors to adjust inks, especially dark ink. In spite of this, everyone has a different perception of color, and the experience and proficiency of deployment are different. As long as you understand the basic principles of color, you can also fully use "waste" ink. The reason is the three primary colors of pigments (Y, M, C). The three primary colors of the colorant are Magenta Red and Cyanine Blue. The darker the three colors are, the lesser the color mixture is, and the three primary colors are mixed into black. Theoretically, the same amount of magenta, cyan, and yellow are printed together to produce black, but because ink production is not perfect, the purity of blue ink is less than the purity of magenta, and the grey color is always reddish. In order to make up for the insufficiency of the ink process, black ink was introduced to enhance the effect of gray and prints could perform better. This is why we use four colors for printing. On this basis, some people even use black ink to completely replace the place where the same magenta, cyan, and yellow inks appear. This technology, called color separation, is called a non-color structure (GCR). Replace spot color inks with less than ideal colors, in addition to gray, but also apply to other colors.

According to the color principle, the "waste" ink can be formulated into gray and black. Based on the degree of grayish black ink, a certain degree of gray-black ink is appropriately added to the newly opened black ink, and the black is completely stirred to form a black color. Since there are also at least two types of black inks (ie, black and black gray), if the printed optical disc is printed in regular four colors instead of spot colors, the effect of using a processed black ink is good. In fact, when deploying, it is not always necessary to deploy gray and black to black. Even the most contrasting whites can be added directly to black or yellow, but the amount that can be added is only very small. In actual operation, other colors such as red, blue, or purple can also be allocated according to which hue of the “wasted” ink belongs to. It should be noted that when there is insufficient experience, it is better to use "waste" ink several times, and not to be too hasty to print out products that are not effective. It should be noted that color is not only a design element, but also a standard for receiving goods. Even if a customer stubbornly accepts a printed product with unsatisfactory color, he may no longer patronize the next time. Many companies lose important customers because of color quality problems. It can be seen that mastering the laws of color presentation and controlling color quality are the technologies that must be mastered in production and production. With advanced equipment alone and without good technical cooperation, in the fierce competition in the industry, it will inevitably be eliminated.
