Master the three primary colors change rule, in order to achieve accurate ink mixing: any kind of color can use different proportion of primary colors mixed into, ink color change, it is use this law.As the primary color ink amount of mixed deployment can become black after (approximation).Color printing ink amount of mixing and adding different proportions of white ink, you can make different color of light gray ink.
If the color printing ink by various mixing ratio, can match the three into a variety of different hue or multicolor, but its hue preference for larger scale primary hue.When two original color amount after mixing, can become a standard three;Both the original color is mixed in different proportions after deployment, can match the three into a variety of different hue, but a large percentage of hue tend to primary hue.In addition, any color ink, add white ink after its hue is more, on the other hand, after joining the black ink, the color becomes dark.
Analysis of original hue: using the theory of complementary color correct partial color, improve the effect of ink.When received after printing color draft, the first response to the colors of the original earnest appreciation and analysis, a basic principle, to master the three primary colors is the foundation of the deployment of any ink color.In general, the application of the three primary colors change rule, in addition to the golden color, any complex color can allocate.However, in the process of technological practice, only by the three primary colors mix out myriad ink color, ink is not enough.Because, in actually making ink pigment is not very standard, and even produce each batch of ink will inevitably have a certain degree of difference in color.So, should also be used in actual work, such as the blue, dark blue, light blue, light blue medium yellow, deep yellow, yellow, red, orange, red, pink, black, green, ink amount, to reach the required ink hue.Many different kinds of ink, but no matter how, in addition to the three primary colors of ink thought, other colors are used to supplement the shortage of the three primary colors.Any complex color, always within the scope of the three primary colors change, as long as mastering the principles, ink also won't be a problem.When the color analysis to determine primary color and secondary color magic and proportion can be allocated.But if the deployment of the hue deviation, are available to correct its hue complementary theory.
Three and color mixing, the so-called three, is composed of two primary color ink deploy mixed together, such as red and yellow to orange hue;Yellow and blue to green;Can be converted into purple red and blue.Two match, can modulate many kinds of three, namely primary color pink and yellow to 1:1 mixing, can get red hue;If available to 1:3 mixing deep yellow;If a 3-1 mixing available red hue.If the yellow and blue color mixing equal amounts, can get green;If 3-1 mixing available green;If available to 4:1 mixing apple green;If the 1:3 mixing blackish green color can be obtained.While multicolor derived from three primary color ink and deployment.If they are in different mixing proportion, can get a lot of kinds of complex color, such as primary colors pink, yellow and blue equal allocation, can obtain the approximate black;One copy each of the two pink and yellow and blue mixed allocate available to brownish red;Pink, one copy each of the four with yellow and blue, red brown is available;If one copy each of the pink, yellow, blue 2, can modulate olive;One copy each of the pink, yellow, blue 4 mixed deployment, dark green and so on can be obtained.
Mix the inky operation method: deployment of ink, according to the original analysis of hue, determine appropriate USES what kind of ink to allocate appropriate.Asked, for example, lake blue color, with visual and practical experience can be prepared.The white ink is the main color, blue is complementary color should be slightly.Such as to be deep some differentiable and royal blue.As to the olive yellow green ink, can be set for a white ink is given priority to, with yellow and blue and a little pink.As long as the main color sure good, other colors are secondary color, should be gradually join stir to mix well.Then, using the two pieces of paper (same as the printing paper) prepared by one piece of paper coated with a little ink, with another piece of paper for printing ink layer thickness, it is compared with the original to see if appropriate.Control sample, the sample for paper scraping ink layer is relatively thin and light, to see some accurately.Ink and master a principle, use less as far as possible different colors of ink, that is to say, can use two kind of ink are adjusted, don't use three kinds of printing ink to adjust, so as not to reduce ink gloss.Scratch, on the other hand, the kind of ink mixing than primary color slightly deep some, so print out the color sample can some.Small kind of ink color standard, can according to their respective proportion of ink, with bulk ink, to ensure the quality of ink, improve the work efficiency.
To sum up, as long as the change law of mastering three primary colors to apply knowledge, good color and analyze and summarize the practice seriously, we will be able to quickly and accurately allocate accurate, bright colors, bright and excellent phase printing adaptability good color ink, in order to improve product quality to lay a solid foundation.
