CDI (Direct Computer Imaging) flexo platemaking not only improves quality, but also brings many advantages to the printing process, such as faster press settings, fewer plate cleaning times, and higher consistency in the printing process. With digital flexo, jobs that would have been done with gravure have now been done with flexo.
The main difference between the traditional flexographic and CDI flexographic plates is that during the production of the plate, the CDI flexographic plate is coated with a black photosensitive layer (black film). The function of the black film is to replace the film in the traditional flexo platemaking process. The CDI flexo plate is prepared by placing the plate directly on the flexographic CTP plate making machine. The image data is transmitted on the laser emitter and the emitted laser light erodes the black film. An image is formed on the surface of the plate, the plate is removed from the plate making machine, exposed and developed. In the VU exposure and development process, the dot shape produced by the CDI flexographic plate is different from that of the traditional flexographic plate. The profile is sharper than the traditional flexographic dot, and the sharp dots improve the quality and performance of the flexographic plate. It is of paramount importance in the control of printing and the final print.
The high-quality printing effect of CDI flexo greatly enhances the confidence of people in the industry, especially packaging printing and packaging users, in flexo printing. In narrow flexo printing, CDI flexo has been widely used because of its high resolution and high quality requirements. In China, 6 CDI devices have been installed in this area. Digital platemaking technology also provides a new competitive opportunity for wide flexo printing. In China, the development of wide-width flexo printing is promoted by food and beverage packaging and personal hygiene product packaging, and the quality requirements in the wide-area field are getting higher and higher. The digital version not only satisfies the need for high-quality printing, but it is easier to use and control in the printing process. The original intention of wide-format packaging printing plants investing in flexographic printing production lines is similar to that of corrugated box printing plants investing in flexible flexographic printing production lines: according to packaging users' needs for printing quality, cost, and other requirements, it is necessary to provide them with more printing. solution.
In the field of corrugated box printing, the printing quality of CDI flexo printing is close to offset printing. The greatest advantage of flexographic printing lies in the fact that the connection production increases efficiency, drastically reduces costs, and reduces losses. Especially after the digital version was adopted, the prepress preparation time was greatly shortened, allowing the printing factory to produce more products per shift, which resulted in higher production efficiency and lower costs. CDI Flexo provides printers with a wider range of options, narrowing the gap between flexographic printing and other printing methods, enabling packaging users to fully enjoy all the advantages of flexographic printing.
