1. Actively apply for product bar code printing qualifications The purpose of China's qualification certification for bar code printing is to increase the bar code printing quality level of printing companies and eliminate the flow of goods with unqualified bar codes from the source. Through this work, it can help printing companies solve the quality problems that appear in the bar code printing process, improve the bar code printing quality control and management, and improve the company's bar code printing quality. At the same time, the printing companies that have obtained the “Certificate Certificate” shall expand the business volume of the certified company through the promotion of the center and its branches and the enterprise to the system members and bar code users so as to increase the market competitiveness of the enterprise and thus increase the economic benefits for the enterprise. Therefore, bar code printing companies should actively apply for bar code printing qualifications.
2. Develop the necessary bar code quality control rules and regulations (1) Barcode Printing Verification System
It is stipulated that when undertaking the bar code printing business, the business personnel must obtain the relevant certification documents from the entrusting unit, verify the validity of the certification, and provide the registration procedures for the certification documents to ensure that the company’s contracted services are legitimate and effective.
(2) Bar Code Design Review System
Procedures and methods for reviewing design manuscripts prior to bar code printing to prevent unsatisfactory manuscripts from entering platemaking.
(3) "Barcode print, printing plate, film management system"
Clearly specify the bar code printing qualified products, non-conforming products, defective products, printing plates, film storage, storage, transfer, supervision and sales procedures and responsible personnel, to ensure that the company's bar code printing the entire process of effective control.
(4) "Barcode Print Quality Inspection System"
Clearly stipulate the responsibilities of each process quality inspector and test the qualified release procedure to ensure that only the tested products can be put into use or processed to prevent the unintended use or shipment of unqualified products.
The above rules and regulations can be formulated separately according to the specific conditions of the company, or they can be incorporated into the company's "Handbook on Quality Assurance of Product Bar Code Printing" as a part of the manual. The corporate product barcode responsibility system is shown in Figure 2.

3. Strengthen technical training and improve the quality of employees. In-house bar code knowledge induction training, organize related personnel to learn technical codes and bar code-related expertise related to bar codes, through training, so that the relevant personnel understand the importance of bar code quality, understand their own work Related barcode technology and regulatory requirements to ensure barcode printing quality.

Third, the bar code design link quality control Product packaging design link is an important part of the bar code quality control. This link is also the most fundamental, most direct, and most economical control link for controlling the quality of barcodes. Personnel engaged in product packaging and product bar code design should be familiar with and understand the national laws and regulations concerning product bar codes and related national standards, and ensure product bar code design quality from the following aspects.
1. The uniqueness of commodity codes In commodity barcode application systems, the differences in commodity and commodity prices are identified by different commodity codes. If two different products are identified by the same code, the computer system treats it as the same product, causing errors in scanning and settlement. Therefore, when designing a product barcode, it is first necessary to check whether the barcode of the product conforms to the uniqueness of the commodity code, and if it does not meet the requirements, it should be promptly corrected.
2. Magnification factor Magnification factor actually refers to the size of a product's barcode. Too large a product's barcode will occupy too much space for packaging patterns or printed text, and it is not practical; too small will easily result in difficulties in printing and reading. Therefore, the size of the bar code should be appropriate, usually based on the size of the outer packaging of goods and the area allowed for printing, the magnification factor of the bar code on the outer package of the goods should be within the range of 0.8 to 2.0, and the general amplification factor should be 0.9 to 1.2, for the 0.8 to 0.9 bar code symbol, quality control is more difficult, and should be carefully selected to use.
3. Empty color match The empty color match means whether the contrast between the color of the bar code bar and the substrate color is in line with the standard. The bar code of a commodity is identified by a dedicated reading device relying on distinguishing the lightness, darkness, and width of the bar. Therefore, the greater the contrast between the bar and the empty bar, the better. In general, white is the bottom and black is the most ideal and safe color combination. Because the color itself can have a variety of changes, so in the choice of empty color match should grasp a principle: empty color as bright as possible, the color as far as possible no blue, black ingredients; bar color as deep as possible, the color should contain blue or black .
4. The printing position of the product bar code The position of the bar code of the product should be based on the principle that the bar code symbol is not deformed and is easy to read. The greater the change in the position of the product's barcode on the product package, the slower the rate at which the cashier looks for the bar code and settles through the scanner, and the lower the retail efficiency. Therefore, the printing position of commodity barcodes should be standardized as much as possible. In order to facilitate the scanning and settlement, the bar code of the product should normally be printed on the "natural" underside of the outer package or in a position where it can be easily scanned and read.
5. The fact that the bar height is truncated to any degree in the height of the bar code symbol of the product will affect the scanning and reading of the bar code. Therefore, the height of the product bar code symbol must not be shortened in principle.
6. The size of the left and right blank area of ​​the blank area product barcode symbol should be enough for the correct reading of the scanning equipment. It should be ensured that there are no characters, graphics, perforations, scratches, etc. in the left and right blank areas of the product barcode. At the same time, the printing position of the product barcode should be far from the edge of the outer packaging of the product to meet the requirements for the blank area of ​​the barcode.

4. Quality Control Point for Barcode Printing 1. According to Article 23 of the "Procedures for the Administration of Commodity Barcodes" during the contracting business stage, business personnel shall inspect the Chinese in strict accordance with the provisions of the "Barcode Printing Verification System" when accepting orders from users. Product barcode system member certificate to ensure that the barcode of the product being printed is a valid bar code used legally. The registration of inspection results shall be the confirmation material for the company to print legal product barcodes. Inspection requirements:
(1) The certificate shall be verified within the validity period according to Article 27, paragraph 1 and Article 30 of the Measures for the Administration of Commodity Bar Codes.
(2) It should be consistent with the manufacturer's identification code in the certificate. The manufacturer's identification code in the product bar code that the entrusting party prepares to print on the product package should match the manufacturer's identification code in the certificate. According to Article 19 and Article 24 of the Measures for the Administration of Commodity Bar Codes, verify the correctness of the manufacturer's identification code.
(3) The name of the system member in the certificate shall be the same as the name of the enterprise on the package of the commodity. According to the provisions of Article 25 and Article 26 of the Measures for Commodity Bar Code Management, the name of the enterprise shall be checked.
When the above contents are all in compliance, they can undertake business or sign a contract, and a copy of the certificate together with the printing contract can be filed for future reference. The retention period should not be less than two years.
2. The verification/test stage of the film/printing plate or printed film provided by the customer is based on the national standard GB12904 "Product Bar Code", GB/T14257-2002 "Location of Product Bar Code Symbol" and the relevant technical requirements of the enterprise, and the inspection or verification of customer's provision The bar code film, printing film, printing plate, etc., to ensure that the above-mentioned items provided by customers are qualified products, so that the final product can meet the quality requirements.
3. The design control stage pays attention to communication and cooperation with customers, identifies and determines customer needs, establishes channels for tracking national laws and regulations, national standards, and international standards, and understands the relevant national laws, regulations, and national standards, and Good staff. And strictly enforce the "barcode design review system" within the company to ensure that the designed products meet the social requirements and technical standards; meet customer requirements and potential needs.
The requirements specified by the customer refer to the requirements clearly stated by the customer in words or oral forms, such as the textual provisions of the printed materials, colors, designs, etc. in the contract, and the relevant requirements clearly clarified by the customer.
The potential customer demand refers to the package printing requirements that the customer does not explicitly require, but the intended or prescribed use of the product, such as the printing of product bar codes shall comply with the requirements of GB12904 "Product Bar Code" and GB/T14257 "Location of Product Bar Code Symbols". Wait.
4. Print samples or batch printing stage through the test of small samples to ensure that the company's process technology, printing equipment, operators, work environment and raw materials can meet the bar code printing quality requirements. After the printing sample inspection passes, it enters the next process.
Through the control of printing process, equipment, environment, personnel, raw and auxiliary materials, inspection and control of semi-finished products, ensuring barcode printing
