Two advantages brought by CTP to the printing production process
Core tip: Due to the characteristics of CTP itself, the step of film output is saved, and the production cycle is saved to a large extent. Originally, in the company's traditional film process, the plate-making process was outsourced, and it took at least one day for the process from document to film. If the CTP process is used, one day is enough to transfer the customer's file to the printed paper, and for the printing machine, it takes time to produce. After greatly shortening the pre-press process time, the output value of the printing machine increases.
From the analysis of the jobs currently output through CTP, there are mainly the following characteristics:
1. It has advantages for products with large volumes, high requirements, and strict control. Taking a company with the most CTP publications as an example, a color box construction order requires 450,000 finished products and 125,700 printed sheets. If calculated according to the printing durability of traditional PS plates of 20,000 to 30,000, 5-6 sets of plates need to be produced. In the end, in the case of CTP publishing, a total of 3 sets of editions were released. Since the current printing workshop is also in the stage of adaptation to CTP plates, the printing durability is only conservatively estimated. Taking the Kodak T98 plate currently in use as an example, its test printing durability can reach 400,000 sheets. In addition, the restoration of files by the CTP output method itself is also unmatched by traditional printing, so for such orders, the CTP process is imperative. Some other products of the company require more than 10,000 finished products and more than 5,000 printed sheets.
2. It has advantages for products with tight delivery times, or when the production cycle is tight. Because in the current company's traditional film printing process, the early-stage film is sent out, and it takes a certain amount of time. Since the trial of the CTP process, it has had great advantages in the accuracy and speed of feedback information. For example, the construction order of a magic box was originally produced in the printing workshop through the traditional film process. The customer was not satisfied with the effect and asked to re-print the film. The reason is that the trapping and overprinting were not properly handled during the traditional film production, so part of the text leaked. , because the customer went to the machine to see the sample, it would take a certain amount of time to re-print the film, so it was transferred to CTP for publishing, and after the corresponding trapping work and timely adjustments were made on the missing text, the final customer signed the sample and expressed satisfaction with the final effect.
3. For products with strict printing requirements, CTP has more advantages in terms of printing reducibility and accuracy than the traditional film process. For example, the printing size of the aircraft box construction order of an electronics company is very large. The process department reported that it is difficult to guarantee the quality of the large-sized film, which usually needs to be redone 2-3 times, which not only affects the production cycle but also reduces the work. Efficiency, so it is converted to CTP process, in the recent mass production; in the case of cooperating with customers to sign samples on the machine, to achieve customer satisfaction.
4. For comprehensive customers, customers who put forward high requirements on product technology and product quality management have advantages. The use of CTP process control is the basis, and the corresponding information required by customers can be provided in time through process software and color management software, which better guarantees the quality of printing services.
Although the characteristics of the current CTP output operations reflect some project advantages, because the company's overall pre-press system has just been established, the overall pre-press awareness is insufficient. Judging from the current trial operation of the CTP project, it is not perfect. The CTP process The control of pre-press is strictly required, so it is undoubtedly a huge challenge for us. Therefore, CTP work efficiency will be more prominent after training.
