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 Beijing laser imagesetters.
The important criteria for checking the success of the repairing circuit board circuit board are achromatic, no self-test, invalid SIC interface, color instability, color cast, sometimes lines, colored color points become thick, lack of color, color cross color, motor does not turn , motor speed is unstable, crash, no communication, weak chromaticity, chromaticity imbalance and other faults.
In practical applications, the electronic typesetting system can also carry out advertising design, cover design, direct color printing for four color films, etc. Of course, this requires adding some necessary external equipment, using an electronic typesetting system for advertising or cover design. The effect is beyond the reach of manpower. Need to have a very large database, you can choose any material to process according to your needs, followed by a wealth of design methods.
In order to meet the needs of customers, some phototype machine manufacturers are producing new phototypesetting machines that can expose film visitors to expose polyester sheets. This is a development market with great potential. It is expected that in the future there will be better users who will use polyester sheets, and the new design for the imagesetter will allow the operator to do more operations on a single drum.
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.
