Deployment of color printing ink is very important, is to master a principle - try to use the same type of color printing ink, the same type of auxiliary materials. Such as the choice of color printing ink "05", auxiliary materials should also match it, in order to improve the printing suitability of color ink. In addition, should try to use as little as possible the number of primary color ink, with two kinds of primary color ink, do not use the third, so as not to reduce the brightness of the ink, affect the color bright degree. Color printing ink deployment is divided into two kinds, one is dark ink deployment, that is, the use of three primary colors or intermediate colors of the original ink, without any diluting agent to deploy out of the ink; The other is light ink, that is, adding diluent to the original ink.
The allocation method and color principle of color printing ink. According to the hue of the original manuscript to determine what color printing ink color to use, and then take the appropriate amount of various colors of ink, on the ink platform for a small amount of deployment. Deployment, should master a principle, that is, in the light ink gradually add dark ink. Cut can not take the first deep ink after adding light ink, because light ink coloring force is poor, if used in dark ink to add light ink method to deploy, not easy to adjust the hue, often make color printing ink volume more adjustment, this is not desirable. When the color printing ink is adjusted to the same color as the original manuscript, you can use the printing paper to scrape the ink sample and compare it with the original manuscript. If there is color bias, add color correction until it meets the printing sample.

Color printing ink hue can calculate their respective amount, in order to proportionally to the allocation of batch. If the use of three primary ink deployment of dark ink, should master their change rules, to improve the effect of ink. If the three primary color printing ink is mixed equally, the color obtained is approximately black; Three primary color printing ink in the two primary colors equal or unequal temperature adjustment, can obtain a variety of intermediate colors, the hue tends to the content ratio of the large color fruit; Multiple colors can be obtained by mixing the three primary color printing inks in various proportions. If black ink is added to any color printing ink, its brightness will inevitably decrease so that the color becomes darker. If white ink is added, its brightness will be improved. Intercolor and compound color can be composed of three primary color printing ink, but from the convenience of deployment, as far as possible to reduce the number of ink types, you can use intercolor primary color printing ink deployment.
In the deployment of multiple color printing ink, should grasp the color principle, must not take "this color point, that color point" to test. For example, sky blue or peacock blue should be used in the blue phase of light lake green ink, and dark blue should not be used to adjust it, because dark blue ink has a red taste, which will inevitably make the color gray and not bright. The same reason, also can not add red dark yellow ink, should be used green light yellow ink. For example, when mixing orange red ink, rose red ink can not be selected, 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 of bright sense.
In the deployment of compound color printing ink, if the use of complementary color law to correct the color bias, the color will be better. If the purple flavor is too heavy in some compound color printing ink, yellow ink can be added to correct it; If the red taste is heavy can be added to the green ink to correct, can play a small amount of addition, adjust the color effect is good. Again, if the black ink is yellowish and the black degree is not enough, a trace of light blue can be added as a color extraction material, because light blue is blue ink with red light, and it is also the result of complementary color.
