The application of offset paper technology in China was the simultaneous development of silver salt, heat sensitive and photosensitive technology. With the introduction of high-power violet lasers, two major systems of thermal offset paper technology with 830 nm infrared laser as scanning light source and violet laser offset paper technology with 405 nm violet laser as scanning light source are gradually formed. Next, let's take a closer look at what paper is on the offset paper.
With the continuous development of computing technology, laser technology, automation technology and the multi-disciplinary integration trend, the level of automatic color matching and color separation plate making of offset paper has been continuously improved, which has played an important role in the development and reform of the national offset printing and dyeing industry. The overall improvement of the modernization and automation level of the offset printing and dyeing industry has brought enormous economic benefits. Although the flexographic thermal offset paper technology has been greatly developed in the past 10 years, the advancement of technology has not stopped, and the pursuit of higher printing quality, faster plate making speed and lower cost in the printing field is There is no end, we look forward to seeing the next leap in offset paper technology.
In recent years, the global offset paper industry has continued to grow and continues to develop in the direction of high quality and colorization. On the one hand, the digitalization and automation of the printing offset paper process are constantly improving. On the other hand, new equipment and new materials for offset paper are constantly being developed. Development has increased industry capacity, reduced product profits, and intensified market competition. In such a large-scale offset paper environment, the trend of large-scale printing equipment and materials has been triggered, making offset paper large-format printing technology an emerging technology system to enhance market competitiveness.
In the actual use of violet laser offset paper, it is an important part to confirm the sufficient polymerization and crosslinking reaction of the offset paper photosensitive resin. Based on actual experience, the following two test methods can be tried. The development process of violet laser offset paper is: purple laser offset paper → preheating (100±6°C) → pre-washing → developing → washing → rubbing protective glue → drying. Among them, all the links need to correctly set the relevant parameters.
