Talking about the Technical Trend of Plate Phototyper

Since the development of the plate-type photo-aligning machine, which was directly imaged by laser on the printing plate since the last century, it has been practically explored in some newspapers. Since the 1980s, as the technology of its peripheral devices has matured, the plateetters have gradually formed a digital workflow. The practical type of phototypesetting machine has also been continuously developed.

The plateetter can be classified according to the photosensitive wavelength of the photosensitive material coated on the image forming medium and the energy required for image formation. According to the wavelength of the light source used, it can be divided into a visible wavelength range and an infrared wavelength range.


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.


At present, thermal plates and thermal platesetters have been put into practical use as mainstream products, and there is a tendency to continue to develop. In addition, in recent years, the violet laser series bright room type plates and the corresponding plate imagesetters have become increasingly active. For a long period of time, the thermal and violet laser systems will be in a coexistence state, and customers using traditional printing processes will gradually join the CTP ranks. Reducing the cost of direct plate making will inevitably lead to the introduction of CTP.


In the future, the development trend of plate-type imagesetters will depend on how to increase production capacity and how to reduce costs. The production capacity of the plate-type photo-setting machine is not only in itself, but also directly related to the production capacity of its peripheral equipment such as plate feeding, discharging equipment and automatic developing equipment. Therefore, a comprehensive evaluation of the CTP system is necessary.
