The printing color sequence should also be arranged according to the type of manuscript
No matter what kind of manuscript, despite its wide variety and different colors, any color manuscript has its main color (that is, the dominant color), and some other colors are subordinate colors (to play a supporting role Colors). Therefore, when matching colors (overprint color sequence is also a kind of color matching), we must obey the principle of master and slave. If the main color cannot be fully expressed in the printed matter, the color tone of the printed matter will be poorly restored, thereby destroying the atmosphere of the entire picture.
The colors of the original are various, but from the perspective of the tonality of the color, the main colors of the screen are either warm colors (yellow, orange, red, etc.) or cold colors (cyan, blue, purple, etc.), Green is a neutral hue and does not give people a warm and cold feeling. If the green is yellowish yellowish green, it tends to be warm, while the cyan emerald green tends to cooler. This shows that neutral tones are few. Therefore, the overprint color sequence of proofing and printing can be summarized into three color sequences from the tonality of color. The main advantages of this color sequence arranged in warm and neutral tones are as follows:
1. Arrange the decisive colors in the most critical third and fourth color sequence;
2. Can meet the requirements of any tone original, easy to restore the tone, and guarantee the consistency of the color of the printed matter;
3. Avoid the influence of ink hiding, so it can better highlight the main color of the picture;
4. The black ink is placed in the first color sequence, which is conducive to the accuracy of other color plates for overprinting and obtaining clear images;
5. The machine operator is easy to grasp and control the ink color.
For the printing color sequence of Chinese ink painting. Traditional Chinese painting is one of the traditional graphic arts in China. The use of ink by Chinese painters is like the use of color, which can make the scenery in the painting give people a rich sense of color. The heavy, light and clear inks are multicolored. Therefore, when copying and printing Chinese ink paintings, the "one gray one black" plate-making process is often used. Only when coking ink is encountered in ink painting, it is necessary to adopt the "one gray and two black" plate-making process, one of which is a special edition of coking ink, and the ideal color sequence in printing is: because Chinese painters are painting Often used techniques such as "Darkness" and "Darkness". In order to better express its techniques, the following printing color sequence can be used: If the "light break" and "dark break" techniques appear on a picture at the same time, it depends on which technique is in the picture. The dominant position determines the printing color sequence. In short, the printing color sequence of ink and wash Chinese paintings must be based on the order of the pen and ink used by the painter in order to fully express the artistic effects of "colorful ink" and "motivating ink" in traditional Chinese painting.
In summary, in order to arrange the printing color sequence, in addition to factors such as the performance of ink and paper, printability, etc., it must be based on the hue of the original, and the color, artistic characteristics, and craftsmanship should be integrated. Comprehensive consideration, so as to obtain the best results of printed matter.
