New ways to optimize commercial CTP applications

In the development of economic globalization, the core competitiveness of printing companies is focusing on how to optimize and apply new technologies and new methods to reduce time-redundancy in print production, cost redundancy and redundant personnel. "On top of that, commercial CTP is a means to reduce printing time, cost, and manpower at the same time. Finding new ways to optimize commercial CTP applications has become a problem for printing companies. After long-term technical research and work practices, the author believes that optimizing commercial CTPs." Applications should start with the following aspects.

Scientific analysis of the advantages of commercial CTP

Commercial CTP is a new production mode that integrates the entire production process from prepress to print and postpress, and is a key technology for implementing color management, digital workflow, etc. in the digital process of printing. It is to provide high quality that fully meets commercial printing requirements. The basis and premise of the printing plate.

1. Correct understanding of the role of commercial CTP

As we all know, the purpose of using commercial CTP technology for printing companies is not to purchase a batch of advanced hardware and software equipment that includes CTP as the main body, covering computers, servers, and digital proofing. Instead, they use advanced knowledge to integrate traditional printing technologies by mastering advanced production equipment. With processes, enhance the competitiveness of enterprises. Therefore, in order to apply commercial CTP, preparatory work must be done in advance, including the construction of a perfect digital environment, the solution of front-end file system interface technology, the improvement of electronic document management and data preservation and retrieval technology, color management, and RIP technology. Optimization, employee training, etc. Only by comprehensively and systematically analyzing the traditional printing process and acquiring new knowledge of mastering CTP and related technologies at a certain cost, can we exploit the advantages of new technologies to achieve color separation screening, tone transfer, and digital proofing in print production. Matching at key points such as large print and printing conditions, using CTP in breadth and depth to increase productivity and enhance business efficiency.

2. Reasonable construction of control methods for commercial CTP applications

To apply commercial CTP, we must integrate all hardware equipment, software tools and process control in the existing production process with new thinking and new vision, scientifically analyze the various control nodes of the original process, and understand the quality and efficiency of each node's product production. The role of commercial CTP can truly become a bridge for the transmission of printed information.

At present, the content of the commercial CTP application control method mainly includes the following four aspects.

(1) Control the accuracy of the commercial CTP's transmission of printed information, that is, to follow, evaluate and select the most appropriate CTP and its control parameters according to its actual printing conditions and quality levels.

(2) To ensure that CTP accurately provides the best information to be transmitted in the printing process, that is, based on the analysis of the side effects that the reproduction accuracy of the over-high dot reproduction may have on the process, the optimization of the difference is based on the printing conditions and the rule of the dot transfer between printed materials. The reproduction requirements of the dots for type printing.

(3) Optimize and improve the promotion of traditional CTP technology to traditional processes, that is, to sum up and build a modular process structure, improve the reliability of commercial CTP applications, and achieve high-precision digital control parameter acquisition, error handling, and setting.

(4) When selecting a commercial CTP plate according to product requirements, full consideration must be given to the different characteristics of the company's commercial print. For commercial prints that emphasize print quality, in particular highlights and dark spots reproduce fine prints. Such as exquisite albums, advertising, etc., should use a large contrast coefficient, good dot uniformity CTP plate for the emphasis on the speed of commercial print, such as color books or ordinary promotional materials, select the gamma coefficient uniformity and moderate uniformity of the CTP plate.

How to optimize commercial CTP applications

Starting from the application of commercial CTP, printing companies will directly initiate the process integration of prepress, printing, and postpress processing. That is, based on the realization of PS and PDF files directly on the basis of printing plates, the process management is realized through the automatic transmission of internal data. Online proofing and PPF/JDF (ClP3/CIP4) file generation can even allow customers to specify paper and ink and track the production status of prints through the Internet. Therefore, new methods for optimizing commercial CTP applications can be summarized as follows.
