How to spell the Gift Boxes And Wrapping Paper octagonal offset printing plate

The packaging or trademark of wine, medicine, food, beverage, daily necessities and other products with octavo offset printing press has the characteristics of low cost, simple operation, stable quality, convenient and fast, and has been widely used by small and medium-sized printing enterprises.

The following talk about the actual work of the plate should consider some issues.

1. The design of commodity packaging or trademark is mostly made by computer, after the output of color film for printing, and then on the machine printing. Whether it is manual printing or electrical printing, it is necessary to consider whether the post-printing process, such as cutting, embossing, hot stamping, laminating and so on, will be affected by the previous process.

2. Wine labels or food and beverage packaging, are usually internal and external packaging integration. The label pasted on the wine bottle is mainly composed of two parts: cap label and body label. Cap mark shape is irregular, and the pattern is complex, most of them should be die-cut. When assembling the cap mark and the body mark should be separated, the cap mark should not be close to the body mark, and there should be room for die cutting and indentation between the cap mark.

3. Note the size of the finished product. After the trademark is spelled into a large version, the four weeks should be set aside about 3mm of wool bleeding room, otherwise, cutting and die cutting will affect the quality of the product because of the white edge.

4. If there is a field or flat net on the upper and lower part of the trademark, the field or flat net should be put together when assembling. For example, there is a field under the wine label. When making the plate, the field and the field should be put together diagonally. In this way, the upper and lower marks can be cut with one knife, and there will be no white edge problem.

5. When assembling, we should consider the problem of opening paper and cutting material, and how to determine the mouth. For small-size octagon paper (975px × 675px) and large-size Octagon paper (750px×1050px), if the spelling is full plate and full edge, and there is 37.5px in the finished product size on one side of the trademark without any text, the white edge can be used as the printing position.

6. Manual collage is usually done on collage coordinates copied from transparent film. When assembling, the size of the finished product should be accurate, and the place should be correct, without skew. For small trademarks, a large number of them are placed in the process of pliation. In order to prevent size confusion in the middle of pliation, the precise positions of fine lines, text and patterns in the vertical and horizontal directions of the trademarks should be marked with the help of transparent pliation coordinates.

7. When assembling plates, it is required to mark the position of rule line, cross line, center line, drag line, corner line, color block and mouth clearly, and all kinds of lines should not be in the finished size of the trademark, otherwise, the dirty line and color block 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 knife can be used to scrape short; Already print can be used to repair the paste on the PS version to be corrected.

8. If the film is 16-open, 32-open, 64-open and other small specifications, it needs to be connected to the plate splicing. Because the film has a certain thickness, the film folds each other, which is easy to generate a gap in the folding when the PS plate or copy the film, so that the vacuum pump can not tightly suction, resulting in the printing plate out of the plate, dot deficiency, no ink.

Solution: one is in the computer output octavo version; The other is to cut the plate according to the actual situation, and scrape the edge of the film thin with a knife to avoid folding.

9. Most of the trademarks or packaging products are multi-color overprints. Only when the printing is accurate can the exact overprint be achieved. The printing order is:

(1) the first base color, after the press color;

(2) Spell the light color first, then spell the dark color;

(3) the text, lines and patterns overprinted by the dot are of high precision, which should be spelled first;

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

The most effective way to test the quality of the collage is proofing, spelling out the version before printing, it is best to offset proofing, to check whether the overprint is accurate, whether the ink hue is consistent with the color of the design manuscript, whether the graphic lines have omissions, and at the same time to check the monochrome, overlapping color C, M, Y, K values, for customers to provide accurate proofreading text, color. The true basis of the pattern.
