In the process of plate making, according to the characteristics of the manuscript, the use of pre-press technology to change the background of certain manuscripts can make the pictures look smooth and smooth. It can also enhance the theme and reflect certain cultural information through different colors to achieve comprehensive improvement of manuscripts. The purpose of platemaking quality. Here, the author will use some of the superficial understanding and experience of the background color in the junior middle school years to discuss with you.
I. Chinese painting
Most Chinese paintings have blanks, that is, the background of rice paper. In the platemaking process, the technical difficulty of dealing with Chinese painting blanks is the most difficult. If you use three primary colors or three primary white balances, the blanks in the figure are inseparable from the printed white paper, destroying the picture composition, and the effects of ink seepage in the high-profile layer will be lost, and some picture atmospheres cannot be well represented. . Therefore, before copying, it is necessary to carefully analyze and study the works of Chinese painting. According to the style and tone of the works, the paper blank is defined as pale gray or light gray, so that the color tone of the background echoes the tone of the work and the work is better reflected. Mood.
Such as fresh and elegant, elegant and ethereal light-colored ink painting, the white paper Y, M, C dot percentage value is set to 4,4,7 or 5,5,8, this light gray background can better express The work contained a rainy, quiet atmosphere.
The percentage of Y, M, and C outlets at Xuan Paper White in the heavy-duty ink-and-wash paintings depicting sunset colors and flowing rivers can be set at 6, 6, 3, or 7, 6, and 4 in light warm gray. It will show a warm tone based on crimson or yellowish yellow, which better reflects the magnificent and dignified features of the work.
In some styles of female-style paintings, the Y, M, and C outlets at Xuan Paper Bai are identified as light yellow and gray at 6, 4, 3, or 7, 4, and 4 to highlight the quiet and elegant appeal of the works.
When copying ancient paintings or antique paintings, the background color should be slightly deeper. The percentages of the background color Y, M, C, and K are set at about 9, 5, 5, and 3. The background color is a bit darker, which can make the background more vivid. For the smooth, better reflect the ancient painting's solemn, rustic features.
Second, calligraphy
Calligraphy works are dominated by prominent writings. White rice paper is often used to make nets. Then black (or gray) borders are added to white paper to maintain the integrity of the work. In the production, if the appropriate background can be used according to the different contents of the wound and the different fonts of the calligraphy, it can bring out the characteristics of the character change and ink, and change the monotonous plate design style of the calligraphy works.
Works with poetry and poetry as the main content can be used to make the background of rice paper light blue, light yellow, light brown, gray, and other light gray lines. Some large inkstones, Weibei tablets, and grasses are more powerful and powerful single wounds. The background is set to camel, fake gold, dark red. In addition, in some albums or corporate promotional materials, in order to reflect the importance of certain inscriptions, layout design usually involves only one or two pieces of artwork on one page. At this time, the background setting is particularly important. The background setting range of these works is relatively large. Light yellow, light green, light blue, light pink, light gray and other pale colors can be used. Darker colors, false gold, etc. can also be used for more intense colors. Sometimes, some texture effects can also be used. , such as marble, wood texture, a combination of small geometric patterns.
Three, photographic
Photographs are widely used in the field of bookmaking, books, magazines, and packaging. Most of these types of manuscripts do not have background features and generally do not need to consider the background. However, when dealing with some special photographic works, using subtle colors cleverly can improve the quality of production.
1. In some anniversaries or address books, standard photos of people are often used, and the hue of the background is not uniform. At this time, it can be said that the original height is classified according to the hue of the original background, and then the saturation and the purity of the background color in the same hue are made the same, or the original background color is unified and made into a color coordinated with the layout.
2. When the manuscripts of some special products are produced, the proper background color can highlight the product features. Such as the production of glassware product specifications, the outer background of the container made of light green or light blue, cool tone background brings out the main crystal clear texture. When making originals such as porcelain and silverware, the background color is processed into black, dark green, dark, dark red and other dark colors, highlighting the characteristics of the subject with a strong contrast effect.
3. In the process of plate making, the background color is used skillfully to increase the production efficiency.
4. Change the color of an area of ​​the original to improve the visibility and usability of the original. The front cover of the Atlas of Sustainable Development of the Yangtze River Economic Zone was produced. After spraying, it felt somewhat unsatisfactory. The manuscript was more eye-catching than the location of the rainbow in the Yangtze River Valley. To highlight the area of ​​the economic zone, the editor deliberately created a white tape about 1.5 mm wide along the edge of the area, and it was firmly attached to the manuscript. However, in the original image, the southeastern region showed deeper red dates and gradually faded toward the west. When entering the headwaters of the Yangtze River in Tibet, due to the vegetation and the influence of snow-capped mountains and white clouds, the color in the map was light and some areas were not even color. The added leucorrhea is stiff and prominent in the southeast, but not in the west. For this effect, the author proposes that the white zone should be changed from west to east by gradually changing the color from darker to lighter. The color is defined as the deepest point in the west, M50%, C40%, and the lightest point in the east is M15% and C210% in lavender. The zone can be seen in the entire map, and it is also in harmony with the surrounding environment, with satisfactory results. In addition, in some architectural photography manuscripts, generally the sky has more space, but due to the surrounding environment and the climate, there are always some debris such as wires and selected plates. In particular, the northern sky is gray and old, and it can also have Selectively make some key original heights into a blue flat screen or a blue transition, which greatly improves the effect of the original image.
Practice has proved that the ingenious and appropriate use of background color is an effective method for improving the production level and improving product quality.
