Talking about the development and application of CTP, we must first understand that to produce high-quality and high-stability prints, good printing plates and standardized plate-making processes are the first focus we should pay attention to. It is difficult to achieve the desired effect if only relying on the adjustment during printing. Generally speaking, the traditional plate-making process needs to go through the process of output film, vacuum suction and UV exposure, plate washing, drying and post-exposure. However, in addition to the problems caused by the film itself, the traditional plate making, such as the film being wet, not easy to preserve, and the inconsistency of the size of the highlight dots caused by the unstable laser energy, etc., during the vacuum suction process, there will often be wind and dirt. Point and other issues. In addition, the expansion of the dots, the highlights cannot be washed out, the lines are crooked, and the dots have been bothering us. In contrast to CTP platemaking, first of all, the step of outputting the film is omitted, and the process of vacuum suction is also directly replaced by laser engraving and imaging. The entire platemaking process is simple and standardized, and it is easier to achieve the goal of gradual to zero; on the other hand, film production The company also began to reduce film production due to the advent of the digital age, which caused film price increases, ordering difficulties, and increased production costs for customers. This is also the main reason why Guangzhou Shangan Company has spared no effort to promote CTP technology in recent years. [next] Below, we will discuss the topic of CTP development and application from four aspects.

Technical advantages of CTP
1. 1% delicate outlets. Compared with the traditional version, the uniformity and reproducibility of the flat screen of the CTP version are improved, especially in the details, such as the human skin can be more delicate performance, even comparable to offset printing, 1% delicate dots can clearly show This can be said to be a leap forward in relief printing technology.
Second, the outlets are stable. The size of traditional plate-making dots will be different due to the different film or vacuum suction, which has become a technical bottleneck that has not been broken for a long time. That is to say, each plate-making needs to be continuously adjusted by skilled technicians. In order to maintain stable quality. In contrast, the CTP version is controlled steadily by the laser engraving machine. The dot size is stable and uniform every time, and quality control is easy and simple.
3. Save material. In the traditional plate-making process, in general, the plate material must be slightly larger than the film in order to make a plate successfully, but in the end, these plates larger than the film part must be cut off, which causes the waste of the plate material. But if you use the CTP version, there is no such waste.
4. Simplify the plate-making process and save costs. As we mentioned earlier, CTP platemaking does not require film, and laser imaging replaces vacuum suction. It seems that it only reduces one step on the surface, but in fact we all know that the step of vacuum suction is complicated and easy to produce wind and dirt. If there is a problem in this step, if it is not found in time, it will cause a waste of the entire printing process, including huge waste of ink, paper, machine time, labor costs, and machine downtime. Even if it can be found in time, it needs to be remade, wasting resources. However, CTP plate-making is to simplify this most controversial step and develop it into a standardized plate-making process, so that the errors in plate-making are relatively reduced, and the cost of manual management of the film is saved, which greatly saves costs.
5. The printing quality is stable. In recent years, Guangzhou Shangan Company has continuously promoted the CTP plate-making technology. In addition to the very simple operation of CTP plate-making, another important reason is the stable quality. If you use the ESKO CDI laser engraving machine, you can print the entire set at a time, even if you reprint, it will not affect the quality; this is the biggest difference from the traditional plate making. If the CTP version's print durability is compared with the traditional version, the CTP version's print durability is improved by more than 20% compared to the traditional version.
In summary, CTP plate-making technology not only greatly reduces the cost of various costs, but also surpasses the quality of traditional plate printing in the past, and has become a good choice for printing companies to improve printing technology.
Application cost analysis of CTP version
Since film and margin are not required, the CTP version requires a smaller plate area than the traditional version, which can save more costs in the long run and will not cause waste. On the other hand, the CTP plate has light printing pressure, less ink consumption, fast and stable calibration speed, can save a lot of time and cost, and can also reduce unnecessary waste of plate materials and paper.
In addition, CTP plate-making does not require the use of film, and saves time and expense in various managements such as film storage. And because you do n’t use film, you do n’t need to use potions, and you can do your best to protect the environment.
It can be seen that CTP platemaking can greatly reduce the cost of users in terms of time, manpower, and cost (plate, ink, paper, etc.). On the whole, it can save about 50% of the total cost.
When using CTP plate, it needs to be properly preserved, pay attention to whether the temperature, humidity and support of the indoor storage place are flat. "Platemaking" is also a very important link.
From the previous article, we already know that one of the technical advantages of CTP plate making is that it is easy to operate, which is especially evident when the plate is washed. When choosing a plate-making machine, pay attention to the softness and density of the brush, because the CTP version has a layer of black film instead of film. You must use a suitable brush to completely wash the black film part, which will not cause printing. The problem. Next, in terms of plate-making conditions, the exposure time is shorter than that of the traditional version, and it is not easy to overexposure, which causes a network jam.
Generally speaking, as long as you choose the right plate washing machine, you don't need to go through lengthy professional training, you only need to match the correct operation process, and the finished products can reach a satisfactory level. On the contrary, if you do not pay attention to the process of washing the plate, its effect may not be demonstrated. To this end, Guangzhou Shangan Company has used years of accumulated industry experience and the latest product information provided by original manufacturers in various countries to successfully develop a plate-making machine that can fully utilize the characteristics of the CTP version.
Application status of CTP in China
The development of the printing industry in the Pearl River Delta region in southern China, especially label printing, has always led the country. And in the technical application of CTP, it has also become increasingly mature.
The current status of the CTP market is sufficient to illustrate the importance of the CTP version-at present, more than 10 large label printing companies across the country have begun to use the CTP version of the printing workflow as their solution (due to customer privacy, we cannot disclose customers name). This workflow can not only improve printing quality, but also reduce costs, and then standardize the workflow.
Although, as of now, CTP has not yet reached the ideal state of popularization, it is for this reason that CTP is more expandable in the label market. Judging by the enthusiastic response from the seminar held by Guangzhou Shangan Company at the Tianhe Mediterranean Hotel in Guangzhou on May 26, the acceptance of CTP by various printing companies has been increasing, which also proves that the market application of CTP will be unstoppable.
