No matter what kind of CTP system, if it can't meet the company's expected goals, it is not an ideal CTP.
The CTP system should meet the following requirements:
● Produce printing plates without defects. The production speed of the printing plates should be compatible with the whole process of the work. Of course, the price of the printing plates must be competitive.
●Easy to operate, workers can get started right away, taking up as little internal resources as possible, such as space, energy and people.
● It should be able to reduce the workflow, speed up production efficiency and reduce costs.
What is the performance of CTP on the market? In the face of the total model, how do you choose? The following table compares the various types of CTP. We define the score of the ideal CTP system as 2. If the score is 1, it means general; if it is 0, it means that it needs to be further improved.
In conclusion
The violet laser diode score is the lowest. This is because the first generation of the violet laser plate making system is almost always low in imaging energy, sensitive to light, and requires high precision in rinsing, resulting in large fluctuations in imaging quality. In addition, the production environment needs to be improved, and environmental protection needs to be strengthened.
The score of the visible CTP system is in the middle. This is because they image higher energy than the violet laser and have better image quality. However, rinsing is still essential in these systems, and the working environment is not good (such as darkrooms or special light). In addition, if it is not well mastered during the rinsing process, quality problems are likely to occur.
Overall, thermal plates have the best performance. However, the thermosensitive polyester-based plates also have some drawbacks, such as slow imaging speed and high energy requirements. The amount of chemicals used for rinsing is also large, and the footprint is not small. A baking plate is usually required before and after plate making.
It can be seen that thermal ablation is the highest comprehensive performance, such as no need for rinsing, high image quality, no special production environment. Thermal ablation technology also paints a blueprint for future printing—eliminating platemaking and direct imaging. However, slower imaging speeds are a bottleneck in thermal ablation techniques.
