Call crazy for inkjet printing, national science awards list

The first prize was launched, and inkjet printing won the second prize. On January 8, at the 2017 National Science and Technology Awards Conference, the key technology research and development and application projects of ultra-high-speed digital inkjet printing equipment won the second prize of the National Technology Invention Award. Since the "two sessions" last year, members of the National Committee of the Chinese People's Political Consultative Conference have proposed a proposal for digital inkjet technology, and the attention of inkjet printing inside and outside the printing circle has increased sharply. Needle booster.

Project Description

According to public information, for the application of ultra-high-speed inkjet in the textile printing and dyeing industry, there are major technical problems such as large data flow, easy deformation of media, easy clogging of print heads, and difficulty in automatically detecting print quality. The current status of the EU monopoly. In response to the three major technical bottlenecks of real-time parallel processing of ultra-high-volume printing data, real-time monitoring and control of printing process, and automatic detection of printing quality defects, it has been divided into multiple technical research groups, and has continued to tackle key problems after dozens of program designs and experiments In more than 5 years, it has broken through major technical bottlenecks, formed three core and key technologies with completely independent intellectual property rights, and successfully developed ultra-high-speed digital inkjet printing equipment. The overall technical level is at the leading international level. It is reported that the products have been exported to more than 20 countries and regions, and have been successfully applied in more than 200 printing companies.

Second Prize of 2017 National Technology Invention Award-R & D and Application of Key Technologies in Ultra High Speed Digital Printing Equipment

Major technological innovations

1. Aiming at the problem of real-time processing of large-volume printing data, a real-time parallel processing engine for ultra-large-flow digital printing data was breakthroughly completed. Using high-performance many-core embedded processors and large-scale FPGAs, through parallel data processing methods, the ultra-high-speed real-time processing and transmission of 425Mbps digital print data by a single sub-processing engine is realized; the real-time of the entire device is formed by 4 sub-processing engines Parallel processing engine, the equipment printing speed reaches more than 1000 square meters per hour, the overall processing capacity is equivalent to 12 Core PCs with a main frequency of 1.8GHz.

2. Aiming at the problem of print image quality degradation caused by medium deformation and nozzle clogging during ultra-high speed printing, a video-based real-time monitoring and control method for printing process is creatively proposed. Through the real-time monitoring and analysis of the print media texture and print head, it not only realizes the automatic adjustment of the print data for the stretch deformation of the print media, but also monitors the print head blockage and realizes automatic cleaning in real time.

3. Aiming at the problem of online detection of ultra-high-speed digital printing imaging defects, an automatic detection method for high-quality printing image quality defects based on an image quality evaluation model is creatively proposed.
