Use hardware to print quality products

1. The importance of process design

The so-called printing process refers to the various specifications, procedures, and methods of operation for printing.

We know that print is a multi-process collaborative product with many processes, complex processes, and ever-changing raw materials. In print production, the quality of the product is the most important, followed by production costs and production efficiency. The quality of a product depends mainly on production, not on inspection. With advanced printing equipment, high-quality raw materials, and high-quality operators, we must also have appropriate and correct process design and strict production process control in order to produce high-quality prints. A book has cover, text, inserts, etc., and it needs to use coated paper, book paper, and generally has several posts, the cover may also be hot stamping, coating or laminating, and the printing equipment used is different. But also after many people, more than one machine collaboration. In the printing production process, the quality and quality of any post are critical, and the pre-process is no better. If the process requirements of the post-process cannot be satisfied, the production task cannot be completed successfully. Any mistake in any link will affect the quality of the final product. The same is true for the production of newspapers. Now a complete newspaper is not only colored, but also red, black and white, and some newspapers are even required to have commercial color printing of light-coated paper. This requires that before the production, we must have an overall planning and layout of the entire printing process, to ensure that the entire printing production process is always in a controlled state, so that the production can be carried out smoothly to ensure product quality, cost and production cycle requirements.

In reality, some printing companies often lack the unified process management between workshops and processes, and the processes before printing and printing, printing, and postpress are often out of touch. Even if you have a good design, the printed effect is not ideal; if you print well, it is difficult to carry out post-press processing. Guaranteed product quality, but increased costs, or delayed the production cycle. Therefore, to improve the printing quality, it is necessary to start from the process design, reduce costs and increase production efficiency, but also from the process design.

In addition, printing companies must consider not only the production needs but also the production process design in order to make technological changes and expand the production of newly purchased equipment so that the performance, configuration, grade, and price of the purchased equipment can be determined. . Such as: whether to purchase a full-face single-color monochrome printing machine or to purchase a two-sided duplex monochrome printing machine, whether to purchase a single-sided double-color printing machine or to purchase a single-sided four-color printing machine, etc., all of which need to be designed from the production process. From the point of view. Especially when a newspaper printing factory purchases a web offset press, it is necessary to pay full attention to it from the perspective of production process design. This is because the newspaper industry has developed rapidly in recent years. The newspaper industry has fierce competition in the market. The market has become the focus of competition and its variables are large. As a result, the number of newspaper editions and color editions is also variable, which increases the number of variables in newspaper production process design. The web offset presses produced by newspapers are expensive, and most of them are imported equipment. They have large investments and low utilization rates. Therefore, printing companies must consider carefully and comprehensively and must be forward-looking when carrying out technological transformation and expanding the production of newly purchased equipment. How to configure the production line, several printing departments, several four-color, eight-color towers, several newspaper folding units, several paper holders and so on. It is necessary to consider not only the needs of production, but also the flexibility and versatility of the production process design, and it can be applied to various modes of production.

2. Problems to be noted in the design of printing process

The following points should be noted when designing the printing process:

1) Pay attention to the role of process design in print production management

First of all, companies should pay attention to the role of process design in print production management, establish relevant process design and management departments, equip necessary process design and management personnel and resources, and assign corresponding powers. At present, small and medium-sized printing enterprises in China do not have a few specialized process management departments, and there is a lack of communication between business departments and production departments. In order to receive orders, the design pursues special effects one-sidedly to cater to customers. Although the order was obtained, the production process of the company was difficult to cooperate with and even failed to produce. Often customers are satisfied with the design and are disappointed with printing the finished product. One of the important reasons leading to product quality problems is that graphic and graphic design is not standardized. In fact, these can be avoided only by paying a little attention before printing. Therefore, companies should pay attention to process design. Secondly, according to the different orders, combined with the actual conditions of the factory, the necessary process planning should be carried out before the printing. For the special products with high quality requirements, relevant process supervisors and technical experts should also be organized to further clarify the process requirements. And quality standards. Whatever the process does, how it is done, and how it is achieved, it forms detailed guidance documents, avoids the blindness of the work, puts the various process policies in place, and enables production to be coordinated and carried out smoothly.

2) Process design should establish a concept of the overall situation

The multi-process nature of printed matter means that the printing process is also a systematic project and must be considered comprehensively. From prepress to printing, to post-press processing, the process requirements of each process, especially the post-press processing (such as books and periodicals) Requirements for pages, bindings, post-press finishing, etc.).

In the process of design can be reconciled with each other, avoiding weaknesses, will undoubtedly play a multiplier role. If the monochromatic ink is thickly printed, but the overprinting accuracy is not high; multi-color machine overprinting accuracy is high, but multi-color overprinting is easy to stick dirty, layout design and production arrangements can be considered for this, there is a great deal of operation and printing quality influences.

3) Process design must be combined with production scheduling

In process design, designers should communicate with production scheduling personnel and coordinate with each other. They must ensure the quality of products, meet the requirements of production process design, and also meet the relative balance of production tasks of various printing equipment in order to obtain maximum production. benefit.

4) The process design must have the consciousness of the process for the sake of the next process

The printing process control should also adopt the "process reversal control" method. Printing and copying is based on manuscripts, plate making as a means, and printing as the purpose of the interconnection process. After receiving a printing order, it is necessary not only to understand the use of the product, the object of use, and the environment in which it is used, but also to consider the various factors that may be encountered in the printing process in accordance with the properties and printability of the printed material requested by the customer. Problems. How to be able to adapt to the operation of the next process to improve efficiency, etc., should have predictability. Therefore, the process design must fully consider the feasibility and economy of the post-process construction, which is crucial to the smooth progress of the entire production and product quality.

5) should master the relevant technical basis

Process design is not only based on print copying scientific theory, but also on the basis of strict process management, material and technical test data, and standardized data of technical process operations. Therefore, it is required that the process designer should first work hard to do a good job in process design and management, fully grasp the production process of the whole printing process and the operational experience of the main technical links, including the cultivation of artistic accomplishments. Secondly, the determination of the process plan must be based on standardized, reliable, and repeatable standardized data throughout the entire production process, and it can appropriately increase the continuously evolving process requirements that are beneficial to the quality level. In addition, unforeseeable or unstable factors should be tested in advance and corresponding preventive measures should be taken so that the final solution can be implemented without any problems. In addition, process design and management personnel should conduct on-the-spot tracking of product production and quality control at any time in the first line of production to verify whether the process documentation is scientific, accurate, and inaccurate, timely feedback and correction, and continue to summarize.

3. Process design and production efficiency

There is a direct relationship between the rationality of process design and the level of production efficiency. We know that each printing factory has its own characteristics. In other words, the technical equipment, scale, and production capacity of each printing factory are not the same and have their own long and weak points. In market competition and printing production, how to give full play to advantages, avoid weaknesses, get the best results, and the best production efficiency are important issues that every printing company manager must consider. These issues are all related to process design. The printing company managers and process designers must be aware of the total production capacity of the company. The number of printing production facilities, the status and performance of the production equipment, the technical quality of the production personnel, and the production cost of the company must be grasp. In this way, the printing company's business managers will be able to target in the market, for example, what business can be accessed, which business can not be accessed; what business can meet the requirements of the customer, according to quality, timely completion of tasks. The process designer can also make scientific and reasonable process design according to the requirements of the product.

Scientific and rational process design can greatly increase production efficiency. This is because:

1) It can proceed from reality, give full play to the advantages of our factory, and avoid weaknesses.
2) It can reasonably arrange production, which not only guarantees the quality of printed products, but also ensures the use efficiency of production equipment.
3) Scientific and rational process design can reduce the conversion time between processes, shorten the production cycle, improve timeliness, and increase production efficiency.

Process design and production efficiency are a dialectical relationship. Sometimes process design requirements are too high, which will reduce production efficiency. However, from a whole point of view, scientific and rational process design can greatly improve production efficiency. Therefore, process designers must master This is a good degree.

4. Should pay attention to the process management in the printing production

Through the above introduction, we know the importance and necessity of the process design in the printing production. However, there are not enough good process design solutions. We must also pay attention to the process management work in the printing production, that is, to strengthen the print The effective monitoring of the printing process means that it is also necessary to improve the execution capability of the process plan so that the established process plan can be implemented in order to ensure the improvement of product quality, delivery time, and production efficiency. To do a good job in the process management of printing production, we should start from the following aspects:

1) Establish a sound management system, serious process discipline

There must be corresponding assessment methods and rewards and penalties. Each product must have a corresponding process flow card, process tracking card, and quality tracking card. Each process and machine must strictly comply with the proofs, process requirements, and standards. And standardize daily operations. Such as plate making exposure, developing test every day, Offset do a good job "four diligence", "three levels", "two small" (diligent ink fountain, diligently wash the blanket, look at the layout of the water, diligently check the printed sheet; roller flat, ink roller Flat, water roller flat; plate surface water, small contact surface pressure).

2) Establishing a learning enterprise and continuously improving the overall quality of employees

Enterprises must establish an effective learning system, regularly organize various forms of quality, skills education and training, and encourage employees to study consciously. Efforts are made to create an atmosphere suitable for employees to learn and communicate, and to link work, training and motivation. At the same time, we must also pay attention to fostering employees' team spirit and rigorous work style.

3) Strengthen process control and quality management at the production site

Do a good job of "three seizures", especially the tracking and monitoring of key products and key processes, we must always check whether the process data and quality indicators meet the standards, and correct and correct the process documents and production process inadequacies.

4) Continuous improvement and improvement of process level

The appropriateness and optimization of the process are relative. With the change of production conditions and technological level of the enterprise, suitable processes may be
