Tips for color printing ink allocation share

first, preliminarily judge the ink color to be used according to the hue of the original, and then take an appropriate amount of each color of ink and put it on the ink mixing table for a small amount of allocation. When mixing, we should master a principle, that is, gradually add dark ink to light ink. Do not take dark ink first and then add light ink, because the coloring power of light ink is poor. If you use the method of adding light ink to dark ink to mix, it is not easy to adjust the hue, often making the ink volume more and more, which is not desirable. When the ink color phase is adjusted to be similar to that of the original, the ink color sample can be scraped with printing paper and compared with the original. If it is still colored, add color to correct it until it meets the printing sample. After the ink hue is difficult to adjust, their respective portions can be calculated so that they can be mixed in batches in proportion. If you use three primary color inks to mix dark inks, you should master their change rules to improve the inking effect. For example, three primary color inks can be mixed with us at any time, and the color obtained is similar to black; The two primary colors in the three primary color ink can be adjusted at the same or different temperature, which can obtain various intermediate colors, and its hue tends to the color fruit with high content ratio; The three primary inks are mixed in various proportions to obtain a variety of multicolor; When black ink is added to any color ink, its brightness will inevitably decrease, resulting in dark color transition. If white ink is added, its brightness will be improved. Intermediate and multicolor inks can be mixed with trichromatic inks, but considering the convenience of mixing and minimizing the number of inks used, intermediate primary inks can be used

when blending multicolor inks, we should grasp the color principle, and we must not adopt this kind of color addition point and that kind of color addition point to try. For example, the blue phase in light lake green ink should be sky blue or Malachite blue, and deep blue should not be used to adjust, because deep blue ink has a red flavor. After adding, it must sometimes adopt casting structure (cast steel, cast aluminum, etc.) to make the color gray but not bright. Similarly, you can't add dark yellow ink that tends to be red, but light yellow ink that tends to be blue should be used. Another example is a year-on-year increase of more than 30%; On the basis of lingering cobalt consumption in the previous two years, rose red ink cannot be used when blending orange red ink, because it has a blue flavor, and the green composed of blue and yellow is the complementary color of red, which will make the ink lack a bright sense. " He said like this

some ink colors have their unique hue, just as the hue of golden red is red with yellow light. When used to mix orange, it will increase the brightness of black. When printing orange, if you can't achieve bright effect with orange ink, and the printing is not realistic, mix golden red and lemon yellow, and the printing color is much better. For another example, to print the green scenery picture in early spring, light yellow ink should be used to mix, which can print the tender green and lovely leaves. If you use dark yellow ink, because the dark yellow ink contains red taste, red is the complementary color of green, the printed leaves must be scorched, turbid, and cannot reflect the breath of early spring
