Application of digital workflow in Folding Box With Special-Shaped Window

 

In today's printing production field, the application of digital information processing and computer control technology has been widely and deeply. The overall concept of pre-press, printing and post-press - "digital workflow" is to integrate the above three different processes into an inseparable system with digital production control information, so that the digital graphic information is completely and accurately transmitted, and the final processing is made into printed products. The formation and progress of digital workflow in the field of printing industry will inevitably promote the further development of the printing industry in the digital environment, improve its competitive strength, and play an important role in information exchange and sharing with other fields.

 

Pre-press digital workflows are now available in a variety of solutions, mainly PostScript workflows, dedicated workflows, bitmap workflows and PDF workflows. Among them, PDF based workflow is the most popular workflow at present, in PDF workflow PostScript data or other data formats are converted to PDF format. PDF avoids the unpredictability of the PostScript page description language, and PostScript files from any application and any platform are converted to PDF format.

 

At present, Hualian Printing is the application of the current leading Prinergy (PrinERGy) workflow based on PDF. Prinergy is a relatively perfect PDF workflow at present, it uses the client/server architecture, the software adopts distributed processing, the main software of Prinergy runs on the server, the operator can operate freely on any PC or Apple computer in the LAN. The client software Workshop written in JAVA language can realize the parallel processing of a job by several operators at different addresses at the same time, which greatly improves the production efficiency.

 

1. Requirements for the application of digital workflow

1. Large capacity and fast network transmission system. During the production of CTP digital process, there is a large amount of data information transmitted on the network, using the Internet and establishing their own FTP website, so as to facilitate customers to upload and download files.

2. Copydot scanner can meet the requirements of converting traditional film into electronic files.

3. The digital workflow is required to be compatible, the data generated by any front-end production software can be interpreted, and the output capacity should be strong and flexible.

4. Establishment of standardized color management system.

5. Mature and stable digital proofing solutions. Digital proofing program plays a more important role in the whole process, to see the performance of digital proofing is mainly to see whether its speed is fast, repeatability is good, whether to save raw materials, but also to see whether it can carry out better color control, especially in the remote proofing matching, CTP curve adjustment and CTP output 3 aspects.

6. Intelligent and reliable large-format solution and large-format proofing equipment.

In short, the construction of digital workflow not only requires the basic conditions of equipment, personnel and materials, but also includes the construction of a perfect digital environment, the solution of front-end file system interface technology, electronic file management and data preservation and backup, network transmission speed, color management and RIP technology optimization and staff knowledge reconstruction training. At the same time, it is necessary to truly according to their actual needs, through the comparison and analysis of old and new technologies and processes, inherit the advantages of traditional processes, give full play to the characteristics of new technologies, and match the key points such as color separation screening, tone transfer, digital proof, large plate and printing conditions, so that the theoretical advantages of digital workflow can be transformed into real productivity. In the face of digital workflow, the effective way to achieve the adaptation of each process can be divided into the following parts.

 

(1) Analyze whether the conditions of equipment, personnel and materials for constructing CTP process are mature.
The CTF process can be used as a basis to gradually form an output solution.

(2) Establish production standards and quality specifications, do a variety of data testing work, and summarize various possible situations, adjust and improve the solution.

(3) Carry out the process and application test of the CTP process, only in this way can we truly realize the normal operation of all production processes of the CTP process and ensure the smooth work of the digital workflow.

 

Second, the application of digital workflow in the prepress center

1.194; With the FTP server as the platform, the integration of high-speed lossless remote transmission technology, easy to achieve two or more places to print, undertake overseas orders and other printing tasks, and in time and quality can be guaranteed.

 

Hualian Printing not only has its own dedicated FTP server, but also provides customers with specific services for confidential file transmission. Customers can transfer files through FTP software or Internet Explorer. The simultaneous use of multiple FTP greatly shortens the file transfer time, and the printing with short delivery time can win time for the post-process, providing a strong guarantee for the off-site printing.

 

2. High-precision drum scanner and platform scanner meet the exact reproduction of various original manuscripts, Copydot dot scanner can convert film into electronic files to achieve CTP output of advertising film.

 

The quality of the original manuscript is one of the important factors affecting the printing quality. Hualian Printing has Heidelberg D3900, D7100 drum scanners and Heidelberg NexScanF4100, Kodak (formerly Creo) EVERsmart select platform scanners, EZIO Color Edge CG19 displays and various auxiliary equipment. Employ senior electrical separation and color personnel who have worked for many years, and provide free hardware and software support and technical training for customers, to achieve a true sense of WYSIWYG.

 

3. The perfect desktop processing system can support a variety of software applications, keep the software update and file compatibility at any time, and flexibly edit and typeset various files to meet the needs of customer design and production.

 

4.194; The powerful and stable Prinergy workflow can directly convert PDF, PS and EPS formats into printable PDF files, and the industry-leading editing tool Preps can easily and quickly assemble single pages into large versions, which can be easily and easily bound in any way. RIP multiple output, can be directly out of digital sample, film and CTP version, Acrobat attached to the Pit Stop tool can edit the final PDF file, modify, for customers to achieve the last minute revision; The Dlove 800v3 internal drum phototypesetter and Lotem 800 Quantum thermal CTP combine with amplitude modulation and frequency modulation screening technology to make the image reproduction more refined.

 

Document interpretation, proofing, output is the top priority of the entire digital process, it can be said that the work of the entire prepress center is around these three tasks, directly related to the normal operation of the entire digital workflow.

 

① Interpretation of documents
The Prinergy workflow is extremely stable and fast in the interpretation of documents. It can correctly explain the files produced by various versions of the software at present, as well as various design effects that are difficult to explain by general RIP, such as transparency and shadow.

 

② Make a proof
The blue paper layout proofing is carried out by the Prinergy workflow directly driving the blue paper proofing press; Digital proofing by Prinergy workflow export TIFF files, through GMG Colorproof software on the digital printer proofing, and can provide customers with remote proofing services, so that customers can not leave the house to see the printing color.

 

③ Damage output
Prinergy workflows can use secondary servers to drive output devices, and Hualian Printing's workflows software and output devices are from the same supplier, so it is very convenient in terms of compatibility, quality management and parameter adjustment.

 

5. Standardized color management system runs through the entire process. A full set of color management tools and software, such as ProfileMaker, Eyeone, SpectroScan, GMG software, etc., perfectly unifies the colors of monitors, digital proofing and printed products, and truly realizes what you see is what you get.

 

6. Powerful file storage space, convenient and fast file backup scheme and fast and stable local area network are essential conditions for digital prepress.

 

7. Prinergy workflow can generate CIP3 files, digital information through the direct connection with the printing press, can realize the control of ink volume and registration control, reduce the presetting machine time, reduce losses, shorten the production cycle.

 

Third, the current problems in the application of digital processes

1. The customer does not know enough about the digital workflow and the electronic documents provided do not meet the requirements of the process. If the ICC embedded in the PDF file does not match the printing factory; PDF file not embedded fonts, etc. Hualian printing prepress Center has a professional technical team responsible for technical support and customer training, they always keep in touch with customers, understand customer needs and provide customers with comprehensive solutions.

 

2. The operability of digital workflows in specific environments needs to be improved. Good equipment, excellent technical personnel do not necessarily have the most effective and practical process. How to produce efficiently and correctly is a problem worth pondering. The environment between the printing plant is different, the strength is different, only according to their own characteristics, in the practice of production and continuous improvement, in order to find their own production process.

 

Hualian printing print more periodicals, and the publication time is relatively concentrated, in just ten days to complete the production of 70 or 80 journals, proofing, output work, if there is no reasonable production process, it is impossible to achieve. The randomness of periodical production is strong, and there is the possibility of revision 1 minute before publication, which is also a challenge to the pre-press work. Only in the digital process can the production task be completed accurately and on time, so we must constantly establish and modify and improve our production process.

 

3. Because some software versions are too new, problems may occur in the back-end server RIP of the workflow, which need to be solved according to the actual situation.

 

4. Customer acceptance of digital workflows needs to improve. For example, whether the network transmission of PDF files is widely used by customers, whether the color of digital proofing can be recognized by customers, whether the adjustment of color of CTP printing can be recognized by customers and so on.

 

In short, the mature application of digital workflow requires not only the configuration of software and hardware to be reasonable, but also how to provide customers with more and more convenient value-added services, and to involve customers in the process, customers are part of the process. The function of digital workflow is to effectively shorten production time, rationally arrange production schedule, improve product quality and save production cost. With the further development of digital workflows, the distance between pre-press and printing will become shorter and shorter, and the printing industry will become more reasonable and simpler in the future. Although many domestic printing enterprises have applied digital workflow, but the degree of digitalization needs to be improved, may be due to the degree of technical mastery, hardware and software configuration and market demand and other factors, most of them are still in the exploratory stage. I hope this paper can be used for reference.
