Chinese character precision photo arrangement is the use of computer and related optical and mechanical technology to input, edit, typeset, output and print Chinese information. The goal of developing this system is to completely renovate the traditional and backward printing industry in China with modern technology. . In the 20th century, with the rapid development of electronic computers and optical technology, the West took the lead in ending the printing of movable type, using electronic photo-distribution technology, while China is still "melting lead with fire, casting words with lead, typesetting with lead type, printing with lead printing "Lead row operation." In the 1970s, China had a large number of printing factories, about 10,000, mostly small factories with backward equipment. This article will introduce you to the sales of Shanghai laser imagesetters.
The imagesetter has given the printer the ability to reach digital production, indicating a conversion process, which in turn has contributed to the development of CTP. The imagesetter as a CTP intermediate program allows the print operator to feel intimate and secure enough.
Many people say that there is no market for the photo machine, but this is not the case. After the film-free direct plate-making imaging process has attracted extensive attention, due to the use of phototypesetting machines, and the developer's investment in research and development and the continuous development of new imagesetters, it is known that the imagesetter still has commercial printing scope. The power that drives the action.
The peripherals of the phototypesetting machine, including the plate feeding and discharging equipment. In the future, the production level of the platesetters will be improved, and these peripheral devices are required to have a higher processing speed. However, as the processing speed increases, the feeding and discharging of the plates becomes more important.
In the specific CTP version of the use of the following should pay attention to the following: CTP plate material use and storage conditions temperature of 20 ° C -25 ° C, humidity of 40% -60%, because the photosensitive CTP version is sensitive to temperature and humidity, must Pay attention to the high temperature and high humidity environment in summer; the life cycle of the developer is from 3 weeks to one month. Replace the developer to clean the developing machine while replacing the developing filter; check the circulation of the developing solution at regular intervals, and the pH of the developing solution fluctuates within the range of 11.75- Between 12.25; CTP version should be carefully checked before the output of the network parameters, such as the number of hanging network lines, output resolution, appropriate linearization options, corresponding printing anti-compensation.
