How to spell the octave offset printing trademark edition

printing the packaging or trademarks of products such as alcohol, drugs, food, beverages and daily necessities with the octave offset printing machine has the characteristics of low cost, simple operation, stable quality and convenience. At present, it has been widely used by small and medium-sized printing enterprises

here are some problems that should be considered in the actual work

1. most of the designs of commodity packaging or trademarks are made by computer. After color separation films are output, they are printed, and then printed on the machine. Whether it is manual or electronic composition, it is necessary to consider whether the post printing processes, such as cutting, embossing, hot stamping and film covering, will be affected by the previous process

2. wine label or food and beverage packaging are usually integrated with internal and external packaging. The trademark pasted on the wine bottle is mainly composed of a hat mark and a body mark. The shape of the cap mark is irregular and the pattern is complex. Most of them have to be die cut. When making up, the hat mark and the body mark shall be separated. The hat mark shall not be close to the body mark, and there shall be room for die cutting and indentation between the hat marks

3 listening and speaking. Pay attention to the size of the finished product. After the trademark is assembled into an octave large version, about 3mm blank bleeding space shall be left around, otherwise, the product quality will be affected due to the white edge after cutting and die cutting

4. if there is a field or flat at the top and bottom of the trademark, the field or flat shall be put together when making up. For example, there is a field under the wine label. When making up, the field and the field corners should be put together diagonally, so that when cutting, the upper and lower trademarks can be cut with one knife, and there will be no white edge problem

5. when making up, the problems of paper opening and blanking and how to determine its mouth should be considered. For small size octave paper (39cm 27cm) and large size octave paper (30cm 42cm), if the full page and full edge are spelled out, and there are 1.5cm words not printed in the finished product size on one side of the trademark, you are welcome to pay attention to the white space of the official station of the company. You can use this white edge as the mouth position for printing

6. manual composition is generally carried out on the composition coordinates copied with transparent film. The finished product shall be accurate in size and placed properly without skew. For small trademarks, there are a large number of them in the process of making up. In order to prevent size confusion in the process of making up, the accurate positions of fine lines, words and patterns in the vertical and horizontal directions of the trademark should be marked with the help of transparent making up coordinates

7. when making up, it is required that the regular lines shall not be removed from the machine, and the positions of cross lines, center lines, trailing lines, corner lines, color blocks, and its mouth shall be clearly marked, and various lines shall not be within the finished product size of the trademark, otherwise, the dirty lines and color blocks that cannot be cut will affect the appearance of the finished product of the trademark. If the line or color block is too long, it can be cut short with a carving knife; The available revision paste that has been printed shall be corrected on the PS version

8. the color separated film needs to be assembled into a large version. If the film is a 16 open, 32 open, 64 open and other small specifications, it needs to be spliced. Because the film has a certain thickness, the films fold each other, which is easy to produce a gap at the fold when drying the PS version or copying the film, making the vacuum pump unable to close tightly, This leads to the failure of the printing plate that is exposed to the sun, such as plate dropping, dot missing, and no inking

solution: first, output the octave version on the computer; The second is to skillfully trim the plate according to the actual situation, and scrape the edge of the film with a knife to avoid folding

9. trademark or packaging products are mostly multi-color overprint. Only when the composition is accurate, can the accurate overprint be achieved. The order of making up is:

(1) first the background color, then the pressing color

(2) first light color, then dark color

(3) the characters, lines and patterns printed by dot superimposing have high precision, and they should be spelled first

(4) first spell the main color, then spell the secondary color

the most effective way to test the quality of the mosaic is proofing. Before printing, it is best to first carry out offset proofing to check whether the overprint is accurate, whether the ink hue is consistent with the color of the design, and whether there are omissions in the lines of graphics and text. At the same time, it is also necessary to check the C, m, y, and K values of each monochrome and overlapping color samples, so as to provide customers with the true basis for proofreading words, colors, and patterns
