Blending method and color principle of dark ink

first, the ink color to be used should be preliminarily judged according to the hue of the original, and then take an appropriate amount of various colors of ink and put it on the ink mixing table for a small amount of blending

when blending, 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 the same color phase of the original, the ink color sample can be scraped with printing paper, and then compared with the original. If it is still colored, add color and correct it until it meets the printing sample

after the ink hue is adjusted, 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, if the three primary color inks are mixed in equal quantities, the color obtained is similar to that of ink; The two primary colors in the three primary colors ink can be mixed in equal or unequal amounts to obtain various intermediate colors, and their hues are biased towards 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 can be made with trichromatic inks. After the impregnation process and the cooling of the thermoplastic prepreg blank, but considering the convenience of mixing and minimizing the number of inks, intermediate primary inks can be used

when blending multicolor oil and actively promoting product inks, we should grasp the color principle, and we must not adopt this kind of color addition point, which is the price color addition point of two products 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 taste, and the color will be gray but not bright after adding

similarly, dark yellow ink that is reddish should not be added, but light yellow ink that is bluish should be used. For another example, when matching orange ink, you can't choose equal rose 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

the color of some inks has its unique hue, just as the hue of golden red is red with yellow light. If it is 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, when printing the green scenery picture in early spring, light yellow ink should be used to mix. The model with the largest selection of 5 tons that can print leaves is bright green and cute. 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

when blending multicolor inks, if the complementary color law is used to correct the color deviation, the color matching effect will be better. For example, if the purple flavor in a multicolor ink is too heavy, yellow ink can be added to correct it; If the red flavor is too heavy, green ink (such as malachite blue or sky blue ink) can be added to correct it, which can play a role of less dosage and good hue adjustment effect. Another example is that the black ink is yellow and the blackness is not enough. A small amount of radiant blue can be added as the color enhancer, because radiant blue is a blue ink with red light, which is also the result of complementary color
