Quality Management of Packaging and Printing--Specification of Driving Quality (I)

For packaging and printing companies, product quality is extremely important. It not only relates to the credibility of the company, but also directly affects the sales market and economic benefits of the company. Therefore, quality is the life of the company and the lifeblood of the company. From the perspective of the end-user, the uniqueness of the brand puts higher requirements on the appearance of the packaging. Compared with non-packaged printing, the quality requirements for packaging and printing are more demanding and quality management is more challenging. In this hot issue, we approached the domestic well-known packaging and printing enterprises and learned their successful quality management experience and experience, so as to jointly improve the quality competitiveness of China's packaging and printing enterprises.

The first rule is not a radius - standard drive quality

Printing is an industry with experience and technology. Relying on experience to do things is a major feature of this industry. Moreover, a wide variety of packaging products, printing processes and a wide range of processing procedures, so many processes add a lot of uncertainty, but also become the biggest flaw in improving quality.

The completion of a packaged product is not what one would do if he or she wants to do it. Especially when the product is mass-produced, the process must have a set of standard business processes to regulate, and a complete set of job instructions must be developed.

From the experience of successfully packaging India and China, the IS09000 quality management system has become a powerful tool for standardizing operations and improving quality.

The successful packaging quality management experience of India and China has proven that the more specific the working standards, the more beneficial the operation and control. The workflow-based method of work plays an active role in controlling specific aspects of work standards. It clearly specifies the specific work and standards of the job, and enables employees with different skills and qualities to work in accordance with work processes and standards, thereby reducing work quality. Reliance on human factors. The level of work standardization determines the level of product quality, production efficiency and other aspects.

Standardization is indeed conducive to print quality control, can effectively reduce production costs and improve service levels. The printing production process is long and complicated. The control of printing quality lies in the whole process. Any one process link is not handled properly. The skill level of operators in each link is uneven, and operation is not standardized, and it is impossible to produce printing quality products.

Dongguan Hucai introduced the IS0 quality management system in 1994. It is at the forefront of the industry in implementing standardization. In the course of implementing standardization and standardization operations, Tiger Color has never stopped. Tiger Color introduced and continues to implement the [S09000 Quality Management System]. Its purpose is mainly to use and utilize this internationalized management model to strengthen and standardize the company's management, so as to ensure the smooth running of all tasks and achieve quality excellence. Combined with the requirements of international standards, Hu Cai has formed a set of IS09000 file system with its own characteristics and perfection. It contains four levels.

The first level is the quality manual, which clearly stipulates the quality policy of Tiger Colors – high quality of employees, best in everything, zero defects, and an outline of the file structure of the quality system.

The second level is the program file, which is a supporting document for the quality manual, and is a detailed description of the methods used for various quality activities.

The third layer is the operating instructions, that is, refer to the provisions of the program document, the development of technical operating instructions to guide the operation of the small temperature and humidity control, operation and maintenance of the equipment, process inspection control and other operating specifications.

The fourth level is a form record, which is in accordance with the record format formed by the program document and operating instructions. 'The purpose is to provide verification for situations where retrospective requirements are required and corrective and preventive measures are taken.

For each production process, control points and control elements are set up, and process control is performed based on whether or not the standard requirements are met as a basis for inflows to the next process.

The so-called standardization is in fact the greatest degree of standardization. The same process conditions, in different locations, at different times, different operations staff to print, the effect should be exactly the same. This requires measuring and controlling the process parameters and stabilizing the process conditions. This requires that in the printing process, according to the characteristics of the company, determine the key processes, all processes in the printing process are controlled, in order to achieve the purpose of professional production.

Taking the CTP work flow, which is currently more rampant in large-scale printing enterprises, as an example, the CTP system is required to standardize the required data during the document production and evaluation period, including the production of curve parameters and various aspects of process parameters. So that you can quickly call the corresponding data in production use. At the same time, CTP can accurately quantify multiple links that cannot be precisely controlled in quality, such as manual copying, imposition, printing, and Chinese version in the traditional workflow, and can be easily implemented in one step. In addition, the CTP process can be combined with the COM system to quickly and accurately send the prepress data to the computer of the printing press. This allows the captains to print the new order as if it were the old one. The standard ink is standard. Quantity distribution parameters. Any captain only needs to transfer the printed work order data to use. The standard ink quantity parameter automatically adjusts the ink supply system of the machine, so that the equipment can quickly enter the standby state. The captains can easily get the final result with only minor adjustments. Printing effect.

In the packaging and printing process, a lot of materials are involved. The application of the BOM (Bill of Materials) system facilitates the management of materials. In the BOM system, each product will have a detailed BOM list, which includes the types and quantifications of the required materials. It has been developed during the order review process. With this list, the marketing department and the financial department can calculate the unit cost of the product before the product has been officially produced. Regardless of the number of orders for customers, just click on the MRP calculation in the production planning system. The materials needed for the work order can all be displayed. It is clear at a glance which materials are used in which process and how many quantities are required. Material control and procurement personnel can accurately issue allocation instructions and purchase orders without requiring work order data. In addition, when preparing for production, machine personnel can also clearly check the bill of materials, and they do not need to worry about the wrong materials.

The characteristics of the commercial market lead to the development of the current packaging products in the direction of multi-category and multi-batch. Therefore, the variety of processed products tends to be numerous, and the product process card information system is a standardized management tool.

In the product process card information system, the process flow of the print product and the technical parameters required in the process (prepress production, printing, and postpress processing) and the main raw and auxiliary materials are determined, and the Questions and considerations are reviewed to guide production. A complete process card can be converted into a production work order through the planning department, which can instruct the production departments to easily complete their related work. In addition, the labor cost calculation of the Finance Department, the material calculations of the Planning Department, and the planning schedule are all based on process cards.
