The color management in CTP process is the key and difficult point of CTP technology. The ICC characteristic curve that can accurately reflect the characteristics of the device determines the effect of color management. Therefore, the generation and application of ICC characteristic curve has become the top priority of color management.
First of all, we know that the current violet laser CTP determines that linearization is an indispensable part because of its photosensitivity and the characteristics of the plate processor. Some users are always skeptical of the linearization curve when they use it, and they are not very confident about the accuracy of the device's linearity. After a great deal of use and practice, this worry is completely unnecessary. Some monitoring methods in the process can completely guarantee the accuracy of network restoration.
1. Environmental temperature and humidity control. In a safe light-sensitive environment, the strict control of temperature and humidity is very favorable for the reproduction of CTP outlets. Generally, it is necessary to ensure that the ambient temperature is around 23 and the humidity is between 50-60.
2. Accurate control of PH value. The developing liquid of the plate making machine is periodically replaced as required. The developing solution in the developing tank of the developing machine is measured before each day of publication to ensure that the pH of the developing solution is within the range of 12±0.25 at 28°C. If not enough, add additional fluids.
3. Measurement of the plate tester. In order to verify the accuracy of the numerical values ​​of publishing outlets, a gray ladder output can be attached to the plate layout on the plate. After the plate is printed, the actual outlet value is measured and the difference between the inspection and the required value is checked. The value of the comparison is the value after adding the decompensation curve.
After ensuring that there is no problem with the above three points, the obtained outlet value is completely free of problems. They have become an advantageous weapon for controlling network restoration.
Of course, the PH value reaches a relatively stable state, and it will take some time for monitoring and adjustment. Due to the user's use of plate size and environmental differences, the previous period of installation may be a process of groping the PH value. During this period of time, real-time monitoring of the publication will be carried out. We can find a suitable amount of supplement fluid. Within a certain period of time, if the PH value no longer shows any major changes in the publication process, it means that the adjustment has met the standards. Users can follow the hardware engineers to learn the adjustment skills, and they can make some adjustments when they need it.
