Talking about the treatment of textured version in letterpress printing

With the continuous development of the market economy, the packaging of goods will become more and more exquisite. The materials used are also more sophisticated. Good product packaging not only enables manufacturers and merchants to obtain substantial economic benefits, the price of goods can also rise. Today's consumers are gradually paying more attention to the printing and packaging of goods. Some consumers are more likely to think of printing and packaging as a fake product or a defective product. Therefore, improving the quality of printing and packaging products should not be forgotten.

This year's Spring Festival the author and his family went shopping in the Wanqejiang Shopping Mall and found that some of the trademarks were not well-printed. Because the author is engaged in printing and packaging personnel, I would like to discuss how to print a good version of the anthology and the industry. Now we have years of experience and colleagues to communicate with each other for further progress.

(A) Why Use Screen Screen in Product Packaging?

Under the planned economic system, manufacturers are printing packages for their own goods. Generally, there are two reasons for not thinking about this: The first is that under the planned economic system, the relative shortage of materials is in short supply, and manufacturers do not need to provide products for them. Selling and running around. Second, the awareness of the value of commodity packaging is not strong. Only the simple packaging of goods and the desalination of the packaging and decoration of goods is no wonder. It is no wonder that foreign industry officials claim that our products are first-class goods, second-class packaging, and other third-class prices, which shows the unique economic benefits of commodity packaging. . The party's reform and opening up policy has enabled the printing and packaging industry to grow in size. Toppan printing, gravure printing, and flexo printing have all added a lot to the packaging of goods.

In particular, packaging and printing designers have provided more space for the packaging and printing industry, and thus have a place in the printing industry. It allows consumers to see the products at a glance. For example, wine, canned foods, and beverages mostly use physical screens. The printed chickens, ducks, apples, pears, and grapes are all vivid and vivid, with extraordinary results.

(b) How to print the relief version of the Toppan

Any printer can print an anilox version, but the effects are different. People in the industry are all aware of the quality of the printed version of the anthropomorphic version. The edition is an important part. Reticle version, also known as three-color version of the yellow, red, blue three-color overlay printing press together can make the real lifelike. Before printing, first read and understand the color, once the wrong version, the product will become waste and can not be remedied. The tri-color printing paper generally requires the use of imported copperplate paper or glass cardboard. These materials are relatively expensive, so careful printing cannot be done quickly.

The upper version is divided into two steps, one is to put the version on top, so that it presses evenly on the center of the drum as much as possible to avoid the hairiness of the printing plate. After the plate is processed, it is the key to change the new roll paper and place an open eight-carbon paper inside. After printing the space plate, it will be printed on the white paper in the roller through the copy paper, and then remove the carbon paper. The screen clearly shows which parts should be single mats, which parts are not mats, which parts should be dug, and the parts that are dug away must be made with a knife to have a gradient, so that the net points will not be thrown, and after wrapping the drum, a proof will be seen. Effect, if you are satisfied, you can start printing.

The screen printing roller of the screen is also very particular. Generally, three rollers need to be used to print ink. The rubber roller should be softer, because the ink volume of the screen printing plate is generally very small, and the rubber roller is adjusted to a proper level. Otherwise, it will not only destroy the rubber roller but also cost the printing plate. Because the cost of making a set of screens is three to five times that of the regular version, be cautious. Printed screens must be printed out at the level of the screen. The colors of yellow, red and blue are the main colors, so that the size of the ink can be easily grasped. Each color must be handled with care. Overprinting should be precise, and professional magnifiers are generally used to see if all outlets are covered.

Finally, we will talk about the use of ink, and the use of ink in the three-color anilox version is regulated. We must use 3 prefixes of the original ink, without adding any auxiliary materials. If we take every level off, the three-color printing version printed on the screen will be satisfied with customers, and the benefits of the company will also increase, because the packaging of such products is It is high value-added.
