In the mid-1990s, CTP technology entered the vision of the printing industry. Over the past ten years, through the joint efforts of the majority of equipment manufacturers and material suppliers, especially the plate research department, CTP technology has gradually matured from its original greenness, and its technological advancement and quality stability have also won the majority of users. Recognized. In 2013, CTP technology was even more innovative and continued to benefit printing companies.
Digitization of printed plates becomes a reality
This project breaks through the plate-making process of conventional printing plate materials. As long as the graphic information output by the computer is directly printed on the plate with an inkjet plate-making machine, no photo-imaging process is required, and the ink on the plate can be directly used as the acceptor of printing ink. On-machine printing, this technology not only changes the traditional laser imaging technology such as exposure and development of laser phototypesetting, but also differs from thermal CTP, photosensitive CTP, UVCTP technologies (these CTP technologies have not got rid of the "photo imaging principle") The environmentally friendly bare-plate inkjet CTP technology completely eliminates the photo-imaging plate-making process, making the printing plate-making "out of the light imaging and digitization" a reality.
This project not only saves expensive film costs and technical processes such as film production, manual imposition and cumbersome printing and development, but also eliminates the three forms of pollution existing in the original plate-making technology, including waste water discharge, exhaust gas discharge and light radiation. Dropped to zero. This result is popularized and applied to national publishing, small and medium newspapers and general commercial packaging and printing. It can save hundreds of millions of operating costs for printing companies and effectively solve the environmental pollution problems in the printing industry.
Chengdu Xintu launched FIT Nano inkjet CTP plate
The imaging principle of this technology is to first inkjet onto the CTP plate, then transfer the pattern from the plate to the blanket, and finally transfer the image to the paper. This is one step more than the technology of the digital printing solution that shocked the industry's Landa company without direct printing of plates, but it also reduced the difficulty of imaging. A small printer, after placing the plate, using ordinary conventional ink, print directly as usual, the imaged plate can be output directly, and then can be printed directly on the machine. It has the advantages of fast speed, small footprint and easy operation.
However, as a staged product, this technology will be eliminated once the digital printing equipment developed by Landa is mass-produced. But for now, this product meets the market's variable and green performance requirements, and the common printer's printable features have greatly improved the efficiency of enterprises.
Inkjet CTP is not a new product. In recent years, some companies at home and abroad have carried out research and development. Zhongkona has launched an inkjet CTP solution with completely independent intellectual property rights (but Zhongkona needs to purchase inkjet platemaking equipment), which is supplied overseas In the business, EFI and EPSON are also actively promoting inkjet CTP solutions. The stability of plate printing effects and how to solve the market acceptance of environmentally friendly plate solutions in the post-CTP era have become the key to considering the maturity of this technology.
The development direction of CTP technology
1. Multidisciplinary and diversified development trends are obvious
CTP technology is an automatic production system integrating precision mechanical and optical technology, electronic technology, color digital image technology, computer and software technology, new printing plate and material technology, automation technology and network technology. Only the coordinated development of the above disciplines can Forming another major technological revolution in the contemporary printing industry. In terms of hardware equipment, thermal CTP, violet laser CTP, UV-CTP and inkjet CTP all have different market application forms and have good development momentum; in terms of software processes, digital workflows are used as CTP systems. At the core, the current market technology is quite mature and can achieve stable and efficient operation.
2. Green and environmental protection as the development direction
Now, energy saving and environmental protection have become the main direction of development in all walks of life, and CTP technology is no exception. The continuous improvement of technology, the improvement of the green design level of products and the comprehensive utilization of resources have played an important role in the future development of CTP technology in the direction of energy saving. Low-consumption, low-pollution, low-emission environmentally-friendly processing-free plates and inkjet CTP plates reduce plate-making processing, reduce costs, increase production efficiency, and take a step toward green and environmental protection.
3. Integrated solutions are trends
For enterprises, how fast and cost-effective to print products is the goal, so more companies require equipment suppliers to provide integrated solutions, from pre-press specifications, PDF electronic files, PDF trapping processing to electronic imposition, screening, CTP output, then digital proof matching, color and quality management, automatic output of ink data, printing curve correction, etc. In order to meet the requirements of customers, at present, all major scientific research and supply departments have increased their research and development efforts. At the same time, the competition of equipment suppliers is also concentrated on integrated solutions.
Summary: CTP technology has brought us a technological change. With the breakthrough of CTP new technology, more efficient and environmentally friendly CTP products have poured into the market. While increasing efficiency for the enterprise, it also brings a certain cost pressure. However, environmental protection cannot be completely depended on the invisible hand of the market for printing. Government policy promotion is also necessary. Whether the market demand for green and environmentally friendly CTP technology will surge, thus driving its large-scale production and forming a scale cost advantage, all parties need to work together!
