CTP performance analysis

No matter what kind of CTP system, if it can not meet the company's expected goals, it can not be considered ideal CTP.

The CTP system should meet the following requirements:

● Produce the printing plate without defect, the production speed of the printing plate should adapt to the whole process of the work, certainly the price of printing plate must be competitive.

●Simple operation, workers can immediately start to occupy the company's internal resources as little as possible, such as space, energy and personnel.

● Should reduce the work flow, speed up production efficiency and reduce costs.

What is the performance of CTP in the market? In the face of a wide range of models, how do you choose? The following table compares various models of CTP. We define the score of the ideal CTP system as 2. If the score is 1, it means normal; if it is 0, it means that it needs further improvement.

in conclusion

The violet laser diode has the lowest score. This is because the first generation products of the violet laser platemaking system are almost always low in imaging energy, sensitive to light, and require high precision during flushing, resulting in large variations in imaging quality. In addition, the production environment has yet to be improved, and environmental protection needs to be strengthened.

The visible light CTP system scores are in the middle. This is because their imaging energy is higher than that of violet lasers, and the imaging quality is better. However, flushing is still indispensable in these systems, and the working environment is also unfavorable (such as darkrooms, or require special light). In addition, if it is not well-handed in the flushing process, quality problems easily occur.

Overall, the thermal plate has the best performance. However, there are some defects in the thermal medium polyester plates, such as the slow imaging speed and high energy requirements. The consumption of chemicals used for flushing is also very large and the floor space is not small. Baking plates are usually required before and after plate making.

Visible, thermal ablation is the highest overall performance, such as no flushing, high imaging quality, no special production environment. Thermal ablation technology also paints a blueprint for future printing - eliminating the need for plate making and direct imaging. However, slower imaging is a bottleneck in thermal ablation techniques.
