The two-color printing design simply refers to the process of reproducing the original effect by using a combination of two different color inks for a certain image through a color separation processing technique. In general, in the four-color plates of C, M, Y, and K, the black (K) plate is combined with any other three-color (C, M, Y) plates, because the black plate is in the dark tone. The information distribution is strong and can enhance the contrast of the image tones.
The main points of two-color printing design
In the bright tone, the black tone information is weakened, and the C, M, and Y colors have stronger color levels, which can superimpose the image layer change and color change, and it is easier to reproduce the original color level and order of the image. Tune information. The combination of the three colors C, M, and Y, although the color range is large at the bright tone, lacks image hierarchy in the dark tone, resulting in a small color tone contrast, and it is difficult to reproduce the original effect of the image. Therefore, the two-color printing design mostly refers to the combination of black and other spot colors.
For the two-color printing design, the key is to make the two-color processing of the image. On the basis of fully protecting the original level and tone information of the image, the best coloring effect can be achieved by changing the relationship of the two-color combination to achieve the desired color effect. It is a two-tone in Photo-shop image processing software.
Duotone is the effect of the graphic designer's desired image by adjusting the curves of two different colors. That is to say, the two-color printing design is not a direct reduction of the four colors C, M, Y, K (minus two channels, retaining two channels), but based on the structural principle of the gray mode image itself. Adjust the two colors with the Curve tool and recolor the combination at different levels.
