Dark ink deployment method and color principle

First of all, according to the original hue to determine the color of the ink to be used, and then take the appropriate amount of each color ink, on the ink station for a small amount of deployment. When deploying, one should master the principle of gradually adding dark ink in light-colored ink. Can not add dark ink and then add light color ink, because the light color ink color poor, if you use dark ink to add light-colored ink to the deployment, not easy to align the hue, often make the more the amount of ink adjustment, this It is not desirable. When the hue of the ink is adjusted to the hue of the original, the ink can be scraped with a printing paper and compared with the original. If there is any color shift, correct the color correction until it matches the printed sample.

After adjusting the hue of the ink, the respective weights of the inks can be calculated so that batches can be prepared in proportion. If you use dark inks to mix dark inks, you should master their changing rules to improve the ink transfer effect. Such as: three primary colors ink mixing, the color obtained is approximately black; the two primary colors in the two primary colors equal or unequal temperature adjustment, can obtain a variety of inter-color, the hue is biased to the content ratio of the large fruit; Three primary colors of ink are mixed in various proportions to obtain a variety of complex colors; black ink is added to any color ink, and its brightness must be reduced to cause dark phase. If you add white ink, the brightness increases. The three-color inks can be used for the combination of color and complex colors. However, in terms of ease of deployment and minimization of the number of inks to be used, inter-color inks can be used. In the deployment of complex color inks, we should grasp the principle of color, must not take "this color plus points, the kind of color plus points" to test. Such as the blue lake in the green ink corresponding to the use of sky blue or peacock blue, avoid using dark blue to adjust, because the dark blue ribbon red taste, after joining the inevitable dark color instead of bright. By the same token, it is not possible to add reddish dark yellow ink, and the pale yellow ink should be used. For example, when red orange ink is used, red ink cannot be used because it has a blue taste, and the green color of blue and yellow is a complementary color of red, which makes the ink lack a bright sense.

The color of some inks has its unique hue, just as the reddish hue of red is yellow, and for oranges it will increase the vividness of blacks. Indian orange color, if the effect of orange ink printing does not reach the bright, and the printing is less realistic, with red and lemon yellow mixed, printing color is much better. Another example is that the green scenery of the early spring should be printed with pale yellow ink to print the green and lovely leaves. If you use dark yellow ink tone, dark yellow ink contains red taste, red is green complementary color, the printed leaves must be dark, cloudy, not reflect the breath of early spring. In the deployment of complex ink, if you use the complementary color to correct the color cast, the color effect will be better. For example, if the color of some complex color ink is heavy, the yellow ink may be added to correct; if the red flavor is heavy, blue ink (such as peacock blue or sky blue ink) may be added to correct, and the effect of adding less amount and adjusting the hue effect can be achieved. . Another example is the black and yellow ink is not enough black, you can add a small amount of light blue as a color material, because the blue light is a blue ink with red light, but also the result of complementary color.
