After many years of development, CTP technology has become increasingly mature in technology and quality and is now in the stage of large-scale installation and popularization. Compared with the traditional plate making process, inkjet CTP plate making process saves the process of film, manual plate making, printing plate printing and cleaning, etc. The whole pre-printing process is digital process, which improves the speed and quality, saves the price of film, and truly reduces the cost.
However, a suitable CTP system needs to start from the characteristics of packaging and printing to solve a series of problems that may arise in packaging and printing enterprises in order to meet the needs of packaging and printing enterprises. CTP plate manufacturer technology enters packaging and printing enterprises, and the following problems need to be solved:
Inspection of customer documents before packaging printing, as well as large version and trap printing
For external customer documents, the complex and diverse production software version and various processing effects will bring error opportunities to the pre-printing output. Therefore, the process system should have multiple error checking mechanisms to minimize the possibility of error and the loss to the enterprise. At the same time, packaging enterprises in the traditional production process, manual inspection trap printing, manual large version, time-consuming and laborious, and low efficiency. The CTP system shall assist pre-printing personnel in solving common problems such as indentation, printing plate assembly, ink conversion and pre-flight, etc.
Compatibility with CTF printing plate printing traditional process
Many printing and packaging enterprises still have a certain proportion of live parts to use CTF to print film, and it is inevitable that both processes exist at the same time. This requires the CTP system to be able to solve the compatibility of CTP and CTF processes, without the difference in color between CTF printing and CTP printing. Packing plant reprinting more attention to dot reduction stability.
This is a barrier to CTP in the packaging printing plant, often leaving a piece, when the use of the customer to sign out the approved film repeated printing, worried that CTP repeatedly published, each dot still original difference. The CTP system should combine the stability of the equipment, high precision and professional color process services to ensure the stability of repeatedly published dot reduction and color consistency of multiple reprints.
Packaging printing in production focus on spot color reproduction, color consistency
Compared with color hierarchical reproduction and neutral grey control, packaging printing enterprises pay more attention to spot color reproduction and color consistency. This requires the CTP system to have a color management process control module, which is not only as simple as equipped with hardware equipment, but also needs to provide color debugging and quality control training services, so as to solve the problem of color consistency in actual production.
Digital proofing and the machine proofing process proofing combination. For mass production, it is necessary to establish production control standards and specifications, and a large part of the packaging factory's current proofing is on the printing press proofing, which is approved by customers. As a part of CTP system, color management needs to establish a series of production process specifications and standards to ensure the stability of production and the consistency of digital proofing and printing colors.
Professional, timely and localized service requirements
Since most packaging enterprises have not printed CTP before, they lack experience. After the introduction of CTP technology, suppliers are required to have strong comprehensive service capability, which requires professional, timely and localized features.
Safety and security production needs
For packaging and printing enterprises such as cigarette bags, wine bags and cosmetics, it is necessary to mention fake products and use some anti-counterfeiting technology. At the same time, it can also increase the added value of products and provide more value-added services to upstream customers.
