Laser technology to promote the modernization of printing

Laser is an emerging discipline based on optics, atomic physics, and electronics. Since the world’s first laser was born in the 1960s, laser and laser technology have developed into important high technologies. Its theory and application have revolutionized many technology fields. The printing industry has entered the era of "light" and "electricity." This article only discusses the impact of laser on the development of printing modernization and discusses the important position and application of laser technology in modern printing technology.
Modulator digital printing in digital printing technology is based on a relatively sophisticated computer data processing technology. It combines laser modulation, scanning and imaging technology with high-tech photosensitive materials and new printing inks to achieve computer-controlled printing. Digital integration. It is a modern printing system with a completely different concept and process than traditional printing.
The digital printing process flow is shown in Figure 3, in which the laser modulation and scanning imaging technology is mainly applied in the mechanism version. The color separation data signal (monochrome pixel digital signal) is input to the laser controller during the plate making, so that the emission synchronous monochrome laser beam is converted into a screen data signal through RIP. The laser is modulated and scanned on the plate cylinder. After the photosensitive material on the cylinder is sensitized to form a pattern that can absorb ink or toner, it can be printed.
With the principle of different plates of photosensitive materials can be roughly divided into two categories: one is the laser electrostatic imaging type. Such as Indigo EPrint1000 and Omuius digital presses. The other type is a silicon-based rubber type offset type. Such as Heidelberg's Quickmaster DIC Kuba and KBA and Sailing Angel's 74 Karat digital presses.
The digital printing equipments all have substantially the same laser modulation and scanning imaging system. The system lasers commonly use argon ion lasers and semiconductor lasers, and the acousto-optic modulators of the acousto-optic modulators are lead molybdates (PbMo04) whose electroacoustic transducers are pressed. The transistor is lithium niobate (LiNb03). The modulator is still an important and indispensable core device for transferring graphic information.
Digital printing is an important symbol of modern printing. Personalize on-demand printing. That is, the realization of dynamic or variable image printing will have a major impact on the traditional printing process. Another revolution in traditional printing.
It involves a variety of high technology such as computer information processing technology, laser technology, materials science and so on. They are a whole organic combination. Therefore, laser technology should also be one of the indispensable high technologies for promoting modern printing.
