A suitable CTP system needs to start from the characteristics of packaging printing and solve a series of headaches that plague packaging printing enterprises, so as to meet the needs of packaging printing enterprises and make them benefit from CTP technology. When CTP technology enters packaging and printing enterprises, the following problems need to be solved:
Packaging printing pays attention to spot color reproduction and color consistency in production.
Compared with color level reproduction and neutral gray control, packaging and printing companies pay more attention to spot color reproduction and color consistency. This requires the CTP system to have a process control module for color management, which is not only as simple as configuring hardware equipment, but also provides color debugging and quality control training services to solve the problem of color consistency in actual production.
Combination of digital proofing and on-machine process proofing. Mass production requires the establishment of production control standards and specifications, and a considerable part of the current proofing in packaging factories is proofing on printing machines, and customers sign for approval. As a part of the CTP system, color management needs to establish a series of specifications and standards for the production process to ensure the stability of production and the consistency of digital proofing and printing colors.
Compatibility with the traditional process of CTF film printing.
Many printing and packaging companies still use CTF to produce film for a certain proportion of jobs. It is unavoidable that the two processes exist at the same time. This requires a CTP system that can solve the problem of compatibility between CTP and CTF, so that CTF printing will not occur. Differences with CTP plate-making printing in terms of color and so on.
There are many reprints in the packaging factory, and the stability of dot restoration is emphasized.
This is an obstacle for CTP in packaging and printing factories. Films are often reserved, and when they are used, the films that are signed and approved by the customer are repeatedly printed. They are worried that CTP will be published repeatedly, and the dots will be restored every time. The CTP system must combine the stability of equipment, high precision, and professional color process services to ensure the stability of dot restoration for repeated publications and the color consistency of multiple reprints.
Inspection of customer files before packaging, as well as imposition and trapping issues.
For external customer files, due to the complex and diverse production software versions and various processing effects, there will be opportunities for errors in pre-press output. Losses are minimized. At the same time, in the traditional production process, packaging enterprises manually check the trapping and make the big version manually, which is time-consuming and laborious, and at the same time, the efficiency is low. The CTP system must assist the pre-press personnel to solve common problems such as trapping, imposition, ink conversion, and pre-flight in packaging pre-press processing.
The demand for safe and anti-counterfeiting production.
For packaging and printing companies such as cigarette packs, wine packs, and cosmetics, it is necessary to mention counterfeit products. It is essential to use some anti-counterfeiting technologies. At the same time, it can also increase the added value of products, thereby providing more upstream customers Multiple value-added services.
Demand for professional, timely and localized services
Since most packaging companies have no pre-press experience before CTP, they lack experience. After the introduction of CTP technology, suppliers need to have
With strong comprehensive service capabilities, it needs to be professional, timely and localized.
