Some problems that need to be considered to spell out the octave offset trademark edition

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

here are some problems that should be considered when composing in practical work

1. Most of the designs of commodity packaging or trademarks are made by computer. After color separation film is output, it is printed, and then printed on the machine. Whether it is manual or electronic composition, the post printing processes should be considered, such as cutting, embossing, hot stamping, lamination and bentler siege 3. The loading rate should be accurate; Will a 1600t shuttle double station press in the R & D center in ried im innkreis be affected by the previous process

2. Wine labels 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 logo and a body logo. The shape of the hat logo is irregular and the pattern is complex. Most of them need to be die-cut. When making up, the hat mark and the body mark should be separated. The hat mark should not be close to the body mark, and there should be room for die cutting and indentation between the hat marks

3. pay attention to the size of the finished product. After the trademark is assembled into an octave large version, about 3mm wool bleeding room should be left around, otherwise, the product quality will be affected due to white edges after cutting and die cutting

4. if there is a field or flat on the top and bottom of the trademark, it is necessary to put the field or flat 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, one knife can cut out the upper and lower trademarks, and there will be no white edge problem

5. When making up, we should consider the problems of opening paper and blanking, and how to determine its mouth. For small octave paper (39cm × 27cm) and large octave paper (30cm × 42cm), if the full edge of the full plate is spelled out, and there is 1.5cm non printed text in the finished product size on one side of the trademark, this white edge can be used as the mouth position for printing

6. Manual patchwork is generally carried out on the patchwork coordinates of different types of equipment used in different areas with transparent film. When making up, the size of the finished product should be accurate, and the placement should be correct, and there should be no skew. For small trademarks, there are a large number of them when making up. In order to prevent size confusion in the middle 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 to clearly mark the positions of regular lines, cross lines, center lines, trailing lines, corner lines, color blocks, jaws, etc., and all kinds of lines should not be within the size of the finished product of the trademark, otherwise, the dirty lines and color blocks that cannot be cut off will affect the appearance of the finished product of the trademark. If the line or color block is too long, the user generally applies the universal testing machine, and the pressure testing machine can be scraped short with a knife; The available revision paste that has been printed will be corrected on the PS version

8. the film after color separation needs to be assembled into a large version. If the film is 16 open, 32 open, 64 open and other small specifications, it needs to be spliced with successive versions. 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, so that the vacuum pump can not be closely absorbed, resulting in the failure of the sun printed plate, such as plate falling, dot blurring, and no inking

solution: first, output the octave version on the computer; Second, when making up, trim it skillfully according to the actual situation, and scrape the edge of the film with a knife to avoid folding

9. trademark or packaging products, most of which are multicolor overprint, can be accurately overprinted only if the composition is accurate. The order of making up is:

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

(2) spell light color first, then dark color

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

(4) spell the main color first, and 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 draft, and whether there are omissions in the lines of graphics and texts. At the same time, it is also necessary to check the C, m, y, K values of each monochrome and overlapping color samples, so as to provide customers with the true basis for proofreading words, colors, and patterns accurately
