Introduction to continuous color manuscript

black and white line pattern manuscript includes manual sketch and computer sketch. There are reflective and transmissive manuscripts. Lightweight is a frequently used industrial vocabulary at present. Manually drawing on white paper is projective manuscripts, and words, graphics, tables, etc. drawn on sulfuric acid paper with carbon black Jinan new era Gold Testing Instrument Co., Ltd. ink are transmissive manuscripts. If the density d=3 or above, the silk plate can be directly dried

computer drawing is to draw documents, patterns, tables and other graphics and texts through various software, and output them on transparent film or sulfuric acid paper through a laser printer as a printing manuscript. In order to improve the printing quality, some factories choose high-precision computer sketches

continuous color adjustment originals include:

1. Color reversal film, the most ideal transmission original in printing and reproduction, with high image clarity, bright colors, rich layers, strong stereoscopic sense, suitable for high magnification. Density range d=0 8. Scan with high-end scanner or electric extension to ensure image quality. Magnification can be magnified more than ten times, suitable for large format printing, is the ideal manuscript of large-scale advertising

2. Color photos can be used as reflection drafts by expanding and printing color negatives. There is some loss of image hierarchy in enlargement (copy), and color imbalance, color deviation and uneven hue will occur when the operation is not correct, and the density range is d=0 6. The dye particles are rough and scanned with a platform scanner. The image magnification is times, and then the amplified image is distorted

3. color positive film, copied through color negative film, the image quality is the same as that of color photo, which is a transmission original, and the density range is d=0 8. Scan with a platform scanner and place it at the magnification

there is a horse mask (Amber) on the surface of the color negative, and the black-and-white field cannot be found during scanning. It's bad to catch all the packaging material trends you don't know! Calibration. The picture can't see the effect, and it's difficult to master the color restoration. Image color is the complementary color of the original scene. Generally, it is not used as an original, but can be turned into a positive or a photo as a printed original

however, in the overall situation of macroeconomic structural adjustment and transformation promotion,

printing originals are also called secondary originals, which are mostly eye-catching reflection originals. After compression, y, m, C, K four-color prints have a low density range of 0 6. The level is not rich. The density of reproduction with secondary originals should be consistent and should not be amplified, otherwise it will be seriously distorted. The density of the printed copy is lower than the density recognition ability of the scanner. When scanning with medium and low-grade scanners, first of all, blur processing should be carried out

inkjet printers, laser printers, and laser image setters can output transparencies for printing originals, but the density and image accuracy (resolution) are different

1. inkjet printer, output transparencies and sulfuric acid paper. Bright colored document patterns and black-and-white documents are printed with color ink, but the density of the output film is low and the quality is poor. A negative used for text patterns

2. the laser printer outputs transparent film and sulfuric acid paper, and adopts the electrostatic imaging principle to make the toner adhere to the graphic area on the surface of the photoconductor to form an image. After heating, the toner is melted and fixed on the transparent film base. The image is composed of toner particles, with rough particles, uneven layers, low image density, loss of small dots, deformation of large dots, and many sand holes and black spots on the layout. It is used for printing original with pattern and text color block, and cannot be used as negative of color eye tone original

3. laser image Imagesetter, laser electronic color separation and addition carried out by the crystal modulator or galvanometer system with laser as the light source, which is controlled by the computer to make the laser pass or be blocked, so as to record the exposure on the silver salt film to form an image, and obtain a high-precision spot Silver salt negative film after development. The negative output by laser Imagesetter has high resolution, high density, bright and clean dots and lines, and rich layers. It is the best negative for eye adjustment printing
