The packaging or trademark of alcoholic beverages, medicines, foods, beverages, daily necessities and other products printed by eight-open offset printing machine has the characteristics of low cost, simple operation, stable quality, convenient and quick, and has been widely used by small and medium-sized printing enterprises. Let's talk about some of the issues that should be considered when spelling in actual work. 1. Most of the design of the product packaging or trademark is made by computer. After outputting the color separation film, it is printed and then printed on the machine. Whether it is manual imposition or electric sub-imposition, it is necessary to consider the post-printing process, such as cutting, embossing, hot stamping, laminating, etc., whether it will be affected by the previous process. 2. Wine labels or food and beverage packaging are usually integrated inside and outside. The trademark attached to the bottle is mainly composed of two parts: the cap and the body. The hat marks are irregular in shape and complex in pattern, and most of them are die cut. When the imposition is made, the cap label and the body logo should be separated. The cap label should not be close to the body label, and there should be room for die cutting and indentation between the cap labels. 3. Pay attention to the size of the finished product. After the trademark is assembled into a large version, it is necessary to leave a room for about 3mm of wool bleeding around. Otherwise, the quality of the product will be affected by the white edge after cutting and die cutting. 4. If there are solid or flat nets on the top and bottom of the mark, the field or flat net should be put together when the imposition is made. For example, there is a field under the wine label. When the imposition is made, the solid and the solid corners should be put together diagonally. Thus, when cutting, one knife can cut the upper and lower trademarks, and there is no white edge problem. 5. When you are imposition, you should consider how to open the paper and how to determine the problem of the mouth. For small-size eight-open paper (39cm × 27cm) and large-size eight-open paper (30cm × 42cm), if the full version of the full edge is spelled out, and there is 1.5cm unprinted text in the finished product size on one side of the trademark, the pattern In the blank space, this white border can be borrowed as the position of the printed cornice. 6. Manual imposition is generally done on imposition coordinates copied from transparencies. The size of the finished product should be accurate when it is impositioned, and it should be placed correctly and cannot be skewed. For small trademarks, the number of placements in the imposition is large. In order to prevent size confusion in the middle of imposition, the exact position of the fine lines, characters and patterns in the vertical and horizontal directions of the trademark should be marked with transparent imposition coordinates. [next] 7. In the imposition, it is required to mark the positions of the rule line, the cross line, the center line, the tip line, the corner line, the color block, the mouth, etc., and the various lines should not be within the finished product size of the trademark. Otherwise, the cut can not be cut off. Dirty lines and color blocks can affect the appearance of the finished trademark. If the line or color block is too long, it can be scraped with a knife; the available revision paste that has been printed can be corrected on the PS plate. 8. The film after color separation needs to be assembled into a large version. If the film is 16-open, 32-open, 64-open, etc., the stitching needs to be spliced. Since the film has a certain thickness, the film is folded between each other, and it is easy to be in the PS version. Or when the film is copied, a gap is formed at the folding place, so that the vacuum pump can not be closely sucked, which causes the printing plate to be out of print, the dot is imaginary, and the ink is not inked. Solution: First, output an eight-page large version on the computer; second, ingeniously trim according to the actual situation during the imposition, use a knives to scrape the edges of the film to avoid folding. 9. Most of the trademarks or packaging products are multi-color overprints, and only the imposition is accurate, in order to achieve accurate overprinting. The imposition order is: (1) First color, then color; (2) first spell the color, then deep color; (3) The characters, lines and patterns superimposed on the dots are highly accurate, and are spelled first; (4) first spell the main color, then spell the secondary color; The most effective way to check the quality of imposition is to proof the proof. Before printing, it is best to first perform offset proofing, check whether the overprint is accurate, whether the ink hue is consistent with the color of the design draft, and whether the graphics lines are leaky, etc. It is necessary to check the C, M, Y, and K values ​​of each single color and color mixture to provide proofreading text and color for the customer. The true basis of the pattern.
