The frequency of TP output system update is faster, which makes many operators unable to master the operation technology of CTP output system, so that the production capacity of new equipment cannot be better utilized. In order to solve the above problems, the author briefly summarizes the environmental requirements, parameter settings, common problems and solutions from the CTP output system, so that the operator can adapt to the new equipment more quickly. This article will introduce you to the laser imagesetter.
The price of photographic paper used in the photo-receiving machine is also very high, and the cost of the photo-setting machine itself is also high, so it is only used when high-resolution photocopying is required, such as snapshot cache. The printer has low precision, and the ordinary printing paper is used as a printing carrier, and the price is low. Therefore, the printer for general printing and the photo-aligning machine for high-precision images.
Phototypesetting machine is a phototypesetting machine. Its main function is to photocopy images and text on photosensitive materials, such as photo paper and film.

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 counter-compensation, etc.
