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 Nanjing laser imagesetters.
There are several cutouts in the imagesetter. If a sudden error occurs, the safety switch must first be checked. There have been cases where the release box cutout has become loose, and the circuit that has not been connected to the circuit has started to report an error, and it can be solved after 3 days before and after checking. There are many transformers and magnetic switches in the imagesetter. Sometimes, if you accidentally touch it, it will be damaged. If you damage it, you don't need to buy the original accessories. The domestic transformers and magnetic switches can be used instead.
The installation photo-setting machine needs to be designed according to the manufacturer's environmental requirements. The hardware must be assembled according to the standard to meet the indoor dry humidity requirement. In the rainy and humid season from April to August every year, in order to save, the photo-receiving machine does not pay attention when not in use. The indoor dry humidity standard is dehumidified and moisture-proof when the row is discharged. If moisture enters the imagesetter, the most likely problem is the laser motor of the photo-aligning machine. After the damp, an oxide layer will be formed between the rotor and the stator. Although the camera motor can still work when it is started up, after turning the laser motor by hand, it can easily feel the difficulty of rotation and accompanied by obvious friction sound. Such a laser motor may sometimes work and sometimes not work.
A set of recursive algorithms is designed to restore the compressed Chinese character information into a glyph at high speed, and it is suitable for hardware implementation, paving the way for the design of key laser photo-alignment controllers in the future. What's more unique is that Wang Xuan came up with the idea of ​​using parameter information to control the quality of the glyphs to become larger or smaller, and to achieve high fidelity when the glyphs are zoomed and deformed. This invention alone is 10 years earlier than the West. In September 1975, Wang Xuan simulated the first flaw of the word "human" in the computer through software. This is a major breakthrough in Chinese character information processing technology. The 38-year-old Wang Xuan, with a glimpse of mathematics and wisdom, opened the door to the computer era.
