After publishing drupa1995, the development of printing officially entered a new era. For the next 15 years, CTP did bring a new technological revolution to printing. In the past 10 years, the CTP of China's printing industry grew from the initial number of dozens to more than 2,000 today, an increase of about 200 times, and its growth rate has been particularly rapid in recent years.
Among them, after printing equipment, the initial choice of CTP format by printing companies was mainly based on four-way printing and off-screen printing. Large format CTP is a trend that major printer manufacturers have introduced large format printing presses, about 10 years ago. Only began to push into the market, but has already carved out a lot of the market that originally belonged to the quadrant or the CTP. With the advent of the "large format" era, large-format CTPs have also received corresponding attention from more and more printing companies.
Large format CTP technical points
Large-format CTP is mainly used for books, commercials, packaging, printing, and other fields, and is used in conjunction with full-size offset printing equipment such as the Roland 800 series. In the initial period of promotion, the production speed of large-format CTPs was a major constraint, and its production capacity was only a few to a dozen or so per hour. However, today's large-format CTPs have adopted more and more sophisticated technology processes, thus making it possible for printing companies to use their “handy†applications. But to be "handy", we must first choose. In the following, the author briefly analyzes the main technical points to be noted when purchasing large format CTPs.
1. Adopt advanced GLV laser technology
Exposure using the GLV (grating-like light valve) laser technology can increase the production speed of large-format CTPs to over 30 sheets per hour, which completely solves the problem of previous production speeds. GLV is an exposure system that can adapt to high-speed platemaking operations. It consists of thousands of tiny silicon ceramic chips. When the chip is applied by an external electric field, it will move up and down to achieve the function of reflecting or dispersing the incident laser die-cutting stamping indentation, so that 512 or 1024 beams can be instantaneously exposed on the surface of the thermal plate.
2. Online drilling device
The biggest concern for users in large-format printing is the registration issue. However, in most large-format CTPs, online punching devices have been built in. After the CTPs enter the CTP plate, the online punching device will immediately perform positioning and punching. With the help of positioning holes and positioning pins, it is easy to realize extremely high printing sets. Quasi-accurate government policies and supervision to reduce the exposure error caused by incorrect positioning of the printing plate; in combination with a variety of printing machine punching components, the output printing plate can be printed directly on the machine without manual punching, significantly shortening the printing Preparation time greatly increases overall production efficiency.
3. Double laser double exposure
Super-wide CTP equipment, in order to meet the different needs of customers layout design, also joined the dual-exposure mode, can simultaneously expose the two off-press printing plate, so that the production speed is further improved.
4. Automatic plate loading device
Large-format CTPs should be equipped with automatic plate-fitting devices to ensure stable transport of plates, and can freely extract inter-panel backing papers to make the entire process more automated.
Large-format CTP application status
Large-format CTP printing companies are located in other packaging throughout the country, but mainly in South China, such as Shenzhen Zhonghua Business, Shenzhen Lijia, Zhongshan Hongxing, Shenzhen Langsheng, Dongguan Yongda, Dongguan Hyundai, Dongguan Zhongbian, Guangzhou Zengcheng Racing. Companies such as Banghe and Yongfu have applied.
Among them, taking Shenzhen Langsheng as an example, it currently has two Roland900 and multiple offset printing presses. In 2007, it introduced the first large-format CTP screen and published the god PT-R24000, due to its largest outputable printing plate. The size is 1750mm × 1400mm, so it can meet the requirements of the full-length and offset format printers at the same time; and the CTP's built-in positioning and punching device makes the printing plate overprint accurate book reviews, which can effectively shorten the preparation time for printing, while making plate Stable and efficient. Now Shenzhen Langsheng has nearly 80% of the plate-making tasks transferred to this large-format CTP. Moreover, due to the year-on-year increase in business volume, Shenzhen Langsheng decided to purchase another large-format CTP in 2010 to meet the increased production demand in the future.
Large-format CTP application outlook
Despite the economic downturn in recent years, it has caused great impact on printing companies. However, with more than 100,000 printing companies in the country, only thousands of packaging trades have been installed with CTP. Currently, only 20% or 3 CTP printing companies are required to make up. With a few percentage points, CTP still has a lot of room for development in China.
From 2006 to 2011, it will increase by 22%, which is still relatively high compared to 18% of other printing fields such as book printing. Therefore, it is believed that the demand for large-format CTP will continue to rise. Coupled with the continuous decline in the price of the plates in recent years, it is believed that the large-format CTP will soon reach its peak of application.
