Although many newspaper printing plants already use the CTP system at present, due to the high cost of CTP equipment and the high cost of plate materials, not all newspapers are printed using CTP plate making, and the conventional manual imposition and printing process still dominate.
The standardization and dataization of imposition is relatively easy to achieve. Just draw the standard imposition coordinates (table paper), and the imposition staff can construct according to the sample. However, for printing, the amount of tasks in the relative time is super saturated. In order to ensure the timeliness, the workshop had to sacrifice the quality at the expense of extending the exposure time on the one hand to achieve the purpose of removing dirt; on the other hand increasing the concentration of the developer and speeding up the development degree to increase the production speed. Therefore, the small dots are seriously lost after printing, and the dots below 5% can not be exposed, resulting in a large area of ​​screen area in many highlights during printing, which affects the quality of newspaper graphics.
In fact, the standardization and digitalization of printing are relatively easy to achieve. As long as the standard exposure time and development time are determined, the staff will strictly produce according to the requirements, and there will be no problem.
However, due to the concentration of tasks in many newspaper printing plants, the equipment is often insufficient. To thoroughly realize the standardization and digitalization of printing plates, plate-making equipment and operators must be added. This is an issue that most newspaper printing companies urgently need to solve. Now, many newspaper printing plants pay special attention to the investment of printing equipment and the cultivation of printing talents, but they are reluctant to invest more in the transformation of plate-making equipment and the introduction of plate-making talents. Over time, a situation of "excessive printing capacity and insufficient platemaking capacity" has formed. Therefore, even with advanced printing equipment, high-quality newspaper prints cannot be obtained in the end.
