Three Primary Colors: Color Management of Membrane Switch

Ink formulation is critical in membrane switch process. How well this job is done is directly related to the printing of the products. As we all know, bright colors, good brightness, and accurate hue are the basic requirements for membrane switches. To achieve this requirement, the printing ink must be accurately prepared. Therefore, the colorist must know color and ink adjustment technology well.


1. Changing rules of the three primary colors


Any color can be made by mixing different proportions of the three primary colors (magenta, yellow, and cyan). The hue change of ink is based on this rule. For example, three primary color inks can turn into black (approximately) after being mixed in equal amounts. Mix the three primary color inks in equal amounts and add different proportions of white ink to create various light gray inks of different tones.

If the three primary color inks are mixed in various proportions, they can be mixed into a variety of secondary colors or colors of different hues. If two primary color inks are mixed in equal amounts, they can become standard secondary colors.


After the two primary color inks are mixed in different proportions, they can be mixed into a variety of secondary colors with different hues, but the hue tends to be the hue of the primary color with a larger proportion. In addition, the hue of any color ink will appear brighter after adding white ink.


On the contrary, after adding black ink, the hue becomes darker. The above-mentioned mixing of primary color inks into various colors is based on the subtractive color theory of the three primary colors.


2. Analyze the hue of the original


We use complementary color theory to correct color casts, and improve ink adjustment effects. After receiving the membrane switch color draft, we first carefully appreciate and analyze the various colors in the original draft, and consider the ratios of the ink hues to be adjusted. To analyze the color draft is to grasp a basic principle, that is, the three primary colors are the basic colors for blending any ink color.


By applying the changing rules of the three primary colors, any complex color can be blended except for gold and silver. However, in the process of process practice, it is not enough to use the three primary color inks to prepare countless ink colors. Because, in fact, the pigments used in manufacturing inks are not very standard, and even each batch of inks produced will inevitably have a certain degree of difference in color. Therefore, inks such as medium blue, dark blue, light blue, radiant blue, medium yellow, dark yellow, light yellow, golden red, orange red, dark red, light red, black, and green should be added in appropriate amounts.


There are many types of inks, but no matter what, except for the three primary color inks, other colors are used to supplement the shortcomings of the three primary colors. Any complex color always changes within the range of the three primary colors. As long as you master this principle, adjusting ink won't be a problem.


After we determine the main color and auxiliary color ink and their proportions, blending can be carried out. However, if the blended hue is deviated, the complementary color theory can be used to correct the hue.


3. Methods of ink formulation


When blending inks, it is necessary to determine which inks should be used to blend according to the hue analyzed by the original manuscript. For example, if you want to mix lake blue ink, you can mix it based on visual inspection and practical experience. Among them, white ink is the main color and peacock blue is the auxiliary color and should be added slightly.


If you want it darker, add a little royal blue. If you want to adjust the olive yellow-green ink color, you can make sure to use white ink as the main color, add light yellow and peacock blue and a little pink. As long as the main color is determined, the other colors are auxiliary colors. They should be added gradually and in small amounts and stirred evenly.


Then, take two small pieces of material (the same as the printing material). Apply a little of the adjusted ink on one of them, and use the other piece to scrape it to the thickness of the printed ink layer, that is, compare it with the original to see if it is suitable. When comparing the sample draft, you need to look at the thin and light parts of the scraped ink sample in order to see it more accurately. There is also a principle to master when adjusting ink. In other words, if it can be mixed with two inks, do not use three inks to avoid reducing the gloss of the ink.


On the other hand, the ink color of the scraped sample is slightly darker than the original color, so that the printed color sample can be more accurate. After the ink color of the sample is calibrated, the ink can be adjusted in batches according to their respective ink ratios to ensure the quality of the ink adjustment and improve work efficiency.


To sum up, as long as we master the changing rules of the three primary colors, apply color knowledge, practice carefully and analyze and summarize, we will be able to deploy colors with accurate, bright, bright and good printability. Ink lays a solid foundation for improving the quality of membrane switches.
