How much do you know about the basics of these two-color printing?

    Two-color printing refers to printing with only two colors. These two colors can be spot colors or colors in the four primary colors (C, M, Y, K) of printing. Two-color printed books are very common now. In the early years, the two-color printing that everyone saw was generally "black + red" or "black + blue". To put it simply, it is to extract two of the colors in the CMYK four-color printing, because yellow is limited in recognition when used alone, which is not conducive to reading, so there is no combination of "black + yellow". However, the printed colors of red and blue alone are quite dazzling, giving people a feeling that it is not very high-end. With the reduction of the cost of spot color printing, this processing method has also been introduced in two-color printing. You can use the spot color ink you need to match black, so that the color becomes richer. At present, we are making a book that uses the "black + imitation gold" processing method, and the layout and cover are unified.
