Analysis of manuscripts

The color image copy manuscript is the basis, which determines the basic outline of the copy image quality. Therefore, according to the characteristics of the purpose of image reproduction, the manuscript should be analyzed according to the characteristics of the image reproduction purpose, and the type, content, color, gradation, sharpness, and granules of the manuscript should be comprehensively analyzed to highlight the feature of the manuscript and suppress its deficiency. Determine the process parameters that match the purpose of the copy, the original content, and the artistic reproducibility.

First, the original classification

The plate-making manuscript is a manuscript provided by the user, such as an image, a figure, and a text. From the comprehensive composition of the manuscript, there are six kinds of color reversal films, color transparent positive films, photographs, drawings, prints, and physical objects; from the content of the manuscript, it is divided into landscapes, figures, still life, Chinese painting, oil painting, watercolor, etc.; from the plate-making process It can be divided into the types shown in Table 6-1.

Regardless of the classification, usually the color reversal film, art wood photography photos, drawing quality is better, close to the standard manuscript for easy color separation operations. However, the quality of printed matter, physical objects, and transparent positive films is poor, and comprehensive adjustments are required when separating colors.

Second, the artistic characteristics of the manuscript

In the copying of color images, each manuscript has its own artistic characteristics. Only when the separation and printing is done is enough emphasis on the art and the style and style of the image. Such as the Chinese painting is coke, thick, heavy, light, clear; ancient paintings are simple, stable, and calm; oil paintings are rich in color, strong contrast, clear strokes; watercolors are bright, bright, light and watery moisture; character draft is delicate Rich in layers; subtle textures of still life, machinery, fabrics, fine textures, and sense of space. In addition, when multiple manuscripts form a system such as a picture book, samples, etc., should also pay attention to the characteristics of the times of the manuscripts, mutual coordination and overall effect. Therefore, the operator of electricity distribution plates can only design the original manuscript, but also eliminate the errors in the photographic processing, and fully highlight the artistic features of the work and the color separation of the style, only by fully understanding the artistic features of the manuscript and the artistic effects sought by the author. Control parameters. Therefore, the electricity division platemaking work is essentially a new artistic creation process.
