Build a digital bridge between CTP era publishing house, typesetting company and printing house
Over the years, the vast majority of the publications printed by domestic publishing houses have been based on laser phototypesetter output film (film), and then sent to the printing unit (agent unit or printing agency) for imposition, printing and printing. This film-based publishing process can well guarantee the consistency and reliability of printing results, and at the same time play a role in preventing piracy. However, the film-based publishing process has many disadvantages such as high printing cost, poor printing quality, and low publishing efficiency.
Digital construction-the general trend of the publishing industry
In recent years, digital publishing technologies such as compound publishing and online publishing have been included in the national eleventh five-year plan for development of the press and publishing industry. Many domestic publishing houses have begun to start the construction of digital publishing systems. In the paper publishing of publications, as the phototypesetting machine ceased production, the publishing house used electronic film instead of traditional film to print the publication, which is one of the important contents of digital publishing. The plate-making and printing of China has created favorable conditions, which will greatly improve the printing quality and production efficiency of publications, and at the same time reduce the cost of printing.
So what changes will be brought to publishing houses, typesetting companies and printing houses after the replacement of traditional films with electronic films?
Common electronic files have hidden production risks
We know that in the process of three review and three proofreading of publications, the typesetting staff first uses the typesetting software to group the edited manuscript materials, and then print out the electronic files to output the paper pattern through the printing system (printing software and printer) for editing and proofreading. The personnel check the proofreading, and so the cycle of reviewing the publication can be completed three times. Because in the traditional three-school process, the processing core of the printing system and the plate-making system software used in the printing process are different; the same electronic file (PS, PDF, etc.) generated by the typesetting software is being processed for print interpretation and printing In the process of plate making, the accuracy requirements for printing and printing are different, so the interpretation of the same data is also different, which may cause differences in the results of the two interpretations. If such electronic documents are directly transferred to the printing house for plate-making and printing, the risk of inconsistency between the large sample of the editor's signature and the content of the printing result will be faced. In addition, ordinary electronic files can be copied and used arbitrarily in the process of transmission and plate making, and there is a huge hidden danger of being easily pirated or destroyed.
Therefore, ordinary electronic files cannot be directly used by publishers for printing, and they must provide encrypted "electronic film" files that can guarantee that the large samples are completely consistent with the content of the printed results and that can protect copyright safety. At the same time, publishers need to digitally manage and control the processing, storage, transmission, encryption, and printing authorization of "electronic film" to replace the traditional manual method of film.
Founder electronic film processing and publishing management system to create a full-process digital channel for secure publishing and printing
In order to meet the above-mentioned digital publishing and printing requirements of the publishing house, Peking University Founder has integrated the technical essence of "Free Flow PDF / JDF Workflow", "Overall ERP" and "Data Security Encryption" that have been widely used in the publishing and printing industries for many years Developed a set of publications "electronic film processing and publishing management system" for publication production, proofing, proofing, storage, encryption, transmission, CTP plate printing and other applications. The system includes "electronic film data processing", "electronic film publishing management", "electronic film pre-press platemaking" three parts, mainly used in publishing publishing typesetting, three school inspection, printing management, plate-making printing and other departments.
Both "Electronic Film Processing" and "Electronic Film Pre-press Platemaking" adopt "Founder Changliu (Publisher's Edition)" as the unified system core platform, and implement processing and platemaking applications through different functional modules. In the electronic film data processing of the typesetting company, Founder smoothly used the three-check process for publications, unified control of various printing and proofing equipment for paper pattern output, and realized the "three-check process based on printed PDF", and finally generated inline printing The verification code is in the PDF electronic film file of plate-making printing. In the pre-press plate-making process of the printing house, it realizes the preview control based on "encrypted printing PDF electronic film", folding-to-size, digital proofing, and CTP plate-making output direct control. Because the kernels of the front and back-end systems are completely consistent, the consistency and reliability of the editorial signature and the electronic film printing results are guaranteed.
At the same time, Founder Changliu (special edition for publishing houses) also provides computer-aided proofreading inspection of PDF-based electronic films based on printing, and automatically compares and marks the differences and similarities of PDFs modified in different proofreadings. The page performs PDF page replacement and other functions to ensure the reliability of the content of the non-modified page. [next]
In addition, when the electronic film is generated, the electronic film is pre-printed according to the back-end printing plate setting, and the printing check code is extracted from the dot-matrix information and embedded in the PDF electronic film, so that the electronic film is being revised, When reprinting and reprinting, the system can perform automatic verification and prompt manual intervention on the difference alarm to avoid potential hidden errors due to output results after system upgrade. The electronic film printing verification code can also be used for the pre-comparison inspection of electronic film automatic printing before the plate making by the printing house.
Another part of "Electronic Film Processing and Publishing Management System"-"Electronic Film Publishing Management" is an electronic film publishing management database system based on a set of publications developed based on "Founder Strategy ERP" and "Data Encryption Technology" to realize electronic Film data flow management and security control during storage, review, storage, transmission, printing, etc.
The electronic film publishing management system performs database management on the publication variety information (title, book number, format, edition, printing order and other information), including the production of authorized publishing units designated by the publisher, management of the incoming library, audit inspection, and data Functions such as encryption, transmission, printing authorization, seasonal revision, reprinting and reprinting, variety inquiry, etc., replace the traditional warehouse management of film. The system can carry out printing distribution management and printing authorization management for each publication variety, and the printing unit can realize the remote transmission and automatic download of Internet-based electronic film through the electronic film management system client.
In addition, in the process of electronic film transmission and pre-press plate making, the system adopts multi-level encryption of hardware and software to encrypt the electronic film data multiple times. Encrypted electronic film cannot be opened for reading after leaving a specific environment, and modification is not allowed (the modification is destroyed), and it has no use value after being stolen. The printing plant must obtain the KEY file for the production license of the encrypted electronic film (the KEY file contains the name of the electronic film, the period of use, and the hardware information of the printing plant's plate-making equipment) in order to make plate-making output. The publishing house can also dynamically set and change the effective use period of the electronic film through the electronic film publishing management system, and the electronic film is automatically voided after the use period is exceeded.
Founder Electronic Film Processing and Publishing Management System is for publishing, proofreading and storage of publishing companies, publishing houses and printing houses in the digital publishing era, using network technology, database technology, PDF / JDF workflow technology, CTP direct platemaking process, etc. , Transmission, plate-making, and printing ensure the consistency of published digital content, ensure the data security of publications, and open up a digital channel for the entire process of publishing and printing.
The system will greatly reduce the cost of making and printing publications, improve the efficiency of printing and production and the quality of printing, and improve the management level of publishing and printing processes for publishing houses and printing houses. At the same time, it also provides basic publication resource data in printed PDF, reading PDF, JPG and other formats that are completely consistent with the content of paper prints for other applications of digital publishing of publishers (network publishing, digital printing on demand, e-books, etc.).
Currently, Founder Electronic Film Processing and Publishing Management System has been published in Renmin Education Press, Renjiao Juzhen Typesetting Company, Higher Education Press, People's Publishing House, Science Press, Hebei Publishing Group, Shandong Publishing Group, Anhui Publishing Group, Hebei Xinhua Printing No. 1 Factory, Shandong Xinhua Printing Factory, Dezhou Xinhua Printing Factory, Anhui Xinhua Printing Factory and other units are used in the official publication and printing production of some publications.
