Talk about the mixing method and color principle of color printing ink

The hue, brightness and printability of color printing ink are directly related to the quality of color printing, so it is necessary to correctly grasp the preparation method of ink
.
Today, from the perspective of graphic printing technology, let's talk about the understanding
of color printing ink blending.

It is very important to allocate color printing ink, which is to grasp a principle - try to use the same model of color printing ink, the same model of auxiliary materials coating online coatingol.

.
If the color printing ink "05 type" is selected, the auxiliary materials should also be matched to improve the printing suitability
of the color ink.
In addition, the number of primary color inks should be used as little as possible, and if two primary color inks can be used, do not use the third, so as not to reduce the brightness of the ink and affect the brightness
of the color.
Color printing ink mixing is divided into two types, one is dark ink blending, that is, the original ink of three primary colors or intercolor, without any diluting agent prepared ink color; The other is a light-colored ink, that is, an ink prepared by adding a dilution to the original ink
.

Color printing ink mixing method and color principle
.
According to the hue of the original document, preliminarily judge what color printing ink color to use, and then take an appropriate amount of various colors of ink and put it on the ink mixing table for a small amount of allocation
.
When blending, one principle should be mastered, that is, to gradually add dark ink
to light ink.
It is not possible to take dark ink first and then add light ink, because the tinting power of light ink is poor, if the method of adding light ink to dark ink is used to mix, it is not easy to adjust the hue, often making the amount of color printing ink more and more adjusted, which is not advisable
.
When the color printing ink hue is adjusted to be similar to the original color, the ink color sample can be scraped with printing paper, compared with the original, and if there is still a color cast, the color correction is added until it conforms to the printing sample
.

After the color printing inks are mixed, their respective portions can be calculated so that they can be blended
proportionally.
If the three primary color inks are used to mix dark inks, they should be mastered to improve the ink mixing effect
.
Such as the three primary color color printing ink equal amount of mixing, the obtained color is similar to black; The two primary colors in the three-primary color printing ink are adjusted by equal or unequal amount of temperature, and various intercolors can be obtained, and their hue is biased towards the color fruit with a large content ratio; The three primary color color printing inks are mixed in various proportions to obtain a variety of double colors; If black ink is added to any color printing ink, its brightness will inevitably decrease so that the color phase will become dark
.
If white ink is added, its brightness will increase
.
Intercolor and polycolor can be prepared with three primary color color printing inks, but from the convenience of blending and minimizing the number of inks, intercolor primary color printing inks can be used
.

When mixing multi-color color printing ink, the color principle should be grasped, and "this color plus point, that color plus point" should not be taken to try the adjustment
.
If the blue in the green ink of the light lake should use sky blue or peacock blue, avoid using dark blue to adjust, because the dark blue ink has a red taste, after adding it will inevitably make the color gray and not bright
.
In the same way, reddish dark yellow ink can not be added, but bluish light yellow ink
should be used.
For example, when mixing orange ink, you cannot choose rose red ink, because it has a blue flavor, and the green composed of blue and yellow is a complementary color of red, which will make the ink color lack of
vividness.

When blending complex color printing inks, if the complementary color law is used to correct the color cast, the color grading effect will be better
.
If the purple taste in a certain multi-color color printing ink is heavy, yellow ink can be added to correct; If the red taste is heavy, green ink can be added to correct, which can play a role in increasing less and adjusting the hue effect well
.
If the black ink is yellowish and the blackness is not enough, a small amount of light blue can be added as a color enhancer, because the light blue is blue ink with red light, which is also the result
of complementary color.
