The characteristics of oil painting

The oil painting uses the art of painting in a comprehensive manner, expressive power, and truly express the texture and three-dimensionality of various scenes. Oil paintings are painted on canvas with oily paints. Because oil paintings are painted on the cloth with brushes, they have special brushwork and stacking sensations. The ever-changing colors and colorful colors can be observed from the strokes. The main strokes are intense, deep dark but not dark, light and bright but not thin, and most of the pictures are based on mixed colors. The size of the canvas is generally larger, and it is the most intense type of contrast in the reflected manuscript.

(1) Production of the desktop system for oil-painted printing plates The reproduction of oil paintings should be based on the three primary colors, and the three primary color plates should be long and full.

The white field calibration data is based on the specific oil painting. When the page has a white paint screen, the whitest place can be set as a net. Selected leveled highlights are whitefields. In order to express the texture of the highlight part, it is generally represented by small dots of three primary colors. The black field calibration should pay attention to the fact that the dark areas are not completely black, and the three primary colors adopt the largest change data, and the general data ratios are C95% to 98%, Y, M85% to 92%, and BK55% to 65%. Use black and white contrast.

(2) The electricity production of the oil painting plate requires the copying of the manuscript which is more contact with the electricity. The copying of the oil painting should be based on the three primary colors, and the black version is the skeleton's technological method. As long as they are properly adjusted, they can get more ideal replicas.

For example, oil paintings with moderate contrast, bright colors, thick and regular tone. When copying, you should try to lengthen the plate-making tone, dark tone adjustment to deep (Yang Net Y, M94%, C96%). The black version should be short (80%), and the high-profile office should be networked. The large black manuscript in the figure, Y, M, C dark tone depth can be properly removed, remove the point to start the middle tone, removal of 12%; black parts of the original manuscript, Y, M, C Shadows can be removed or removed as little as possible to make the picture more three-dimensional.
