In the field of the production of large format printed matter, in recent years, it is gradually emerging and cannot be ignored. One production method is screen printing. Screen printing has attracted many customers due to its wide range of substrates, thick ink layers, good weather resistance, and high efficiency and low cost in large-volume printing. In particular, outdoor posters, light boxes, and automobile body advertisements are screen printed. The system accounts for more than half of its total.
Beijing Xijing Advertising Center is a manufacturer that has been printing screen printing large-format prints in recent years. From the initial venture, several people printed stickers in the form of hands-on workshops, and now they have more than 48,000 square meters of factory buildings and advanced sets of imported equipment. Xijing should be a microcosm of the development of China's screen printing industry. A few days ago, the reporter interviewed Pan Liangming, Deputy General Manager of Beijing Xijing Advertising Center on the market and technology of large-scale screen printing.
Screen printing as a traditional process, with the new technology and new materials and the application of the invention, in the large-format printing and re-emerged new brilliance, especially the application of large-scale projectors, breaking through the production of large-scale film "bottleneck." Xijing Pan always stated: “The application of large-scale projection equipment is a leap in our process. This investment has enabled us to gain a leading position in the domestic screen printing office.†Using this large projector, Xijing can use ordinary A4 format film. Directly enlarge the 1.2m-1.6m large-scale film to meet the requirements of the production of large-scale advertisements. In addition, it is the application of large printing presses and various substrates, which greatly improves the production efficiency and enriches the Lu species of printed products. The substrates currently used in Xijing include light box cloth, synthetic paper, rear projection film and Polaroid cloth. The number of printing lines is generally 40-70 lines/inch. It is suitable for viewing from 1-2M. The colors and layers are very rich. The far-sight effect is also good.
When talking about the production of large-format prints, Pan always believed that the computer production in the early period was very important. Silk multi-printing is different from other printing processes in that the ink transfer is obtained through mis-squeezing of the mesh holes. Therefore, the dots below 5% are easily lost, and the dot enlargement is not easy to grasp. Therefore, each original must be adjusted beforehand to make it Meet the requirements of screen printing. In addition, the use of large projectors solves the problem of large-scale film output, ensuring the color consistency of the entire screen, which is also the key to the production of large format prints. In addition, the current screen printing color management and proofing processes can only rely on the operator's experience, so the operator's quality is also very important, in addition to screen printing companies to strengthen corporate management, promotion of standardized operations, but also pay attention to corporate Staff quality training to ensure the quality of printed products. “The equipment we use today is similar to that of foreign countries. The gap is in the quality of operators.†Pan said.
Speaking of the large-format printing market, Pan general believes that silk screen printing is particularly suitable for printing outdoor advertising, advertising for subway light boxes and shelters, and "flowing rainbows" - body advertisements. At present, the main business of Xijing is the above products. Due to fierce competition now, Xijing will continue to develop new products and open up new markets. Retrospectives such as large-scale silk paintings, large-scale land stickers and single-wafer printing are all new products introduced by them. "We are very confident in the current market. Large-format screen printing products will take the lead in outdoor large-scale advertising."
General Manager Pan is also very confident about the development of the industry. “Although many advertisers still do not understand screen printing, they believe that screen printing can only print low-grade products like signage, but as long as we conduct self-promotion, self-promotion, Let them understand the characteristics of screen printing, then the two sides will certainly further cooperation and jointly develop new markets."
In the large-format print market, screen printing has gradually occupied large-scale, mid-to-high-end quality outdoor advertising, light box and car body advertising market with a size of 1.8M×2M and below, due to its own advantages, this advantage will remain longer. a period of time. On the other hand, improving the technological content of large-format screen printing processes and introducing more efficient, scientific, and digital management, especially color management, is also imperative.
