Product barcode is a product identifier that represents a certain place of residence consisting of a group of regularly ordered space and corresponding characters. It is an identity card of a commodity and is a common appraisal of commodity circulation in the international market. Barcodes, generations, and corresponding characters represent the same information. The former is used for machine knowledge, and the latter is used for direct reading by a human or computer input data via a keyboard. There are more than 40,000 members of the existing commodity system in China, and there are 500,000 kinds of commodity items identified by bar codes. In 1998, China's code-changing center changed the quality of bar code prints for the second time. The sampling pass rate was 63.1%, and the samples that were judged to be unqualified due to severe overswings were 29.3%. For the current use of barcodes, it is particularly important for printing companies how to make qualified barcodes and improve the accuracy of barcode identification.
First, improve the sound quality assurance system and sound quality assurance system is to ensure the bar code barcode printing quality premise. In implementing the ISO9002 international standard, we should pay attention to the following points.
1. It is necessary to compile product barcode printing control procedures, standardize the production of commodity barcodes, design a barcode printing workflow, and determine whether the controlled object that affects barcode quality is under control. For example, contract barcode business, original film inspection, plate-making operation, finished product storage, and product inspection.
2. Alleged May Day's operating procedure documents, for certain key sections, should have a complete professional program file or series of program files. In these program files, not only the steps and sequence of quality activities, but also the activities of the Purpose, scope and who will do it and how to do it. Such as each batch of products prepress signing system hospitality, workers self-inspection, mutual inspection of the upper and lower process, quality inspectors special inspection, finished product storage inspection and unqualified product handling procedures, bar code inspection details.
3. Excellent barcode printing, glazing, laminating equipment and necessary commodity barcode testing equipment.
4. The records of all processes are comprehensive, and the products are delivered with inspection reports, certificates of compliance, etc. All quality activities must have record forms.
Second, in strict accordance with the national standard GB12904-1998 test bar code printing quality 1. The quality of the original film production is the key to the correct printing and use of the barcode. When signing the printing business, the system member certificate must be checked and its certificate number must be registered to prevent the system member from borrowing or fraudulently using another person's number and at the same time detecting the original version. The quality of the film, qualified original gel eye can be used. In the case of the entire product packaging area allows, select the largest possible zoom factor for the scanner to automatically read, the value of the zoom factor range is 0.8-2.0.
2. The empty color collocation of the empty color refers to whether the contrast between the strip color and the substrate color in the barcode conforms to the standard. The commodity barcode is identified by the dedicated reading device relying on the distinguishing strip, the empty borderline and the width and the width. The bigger the contrast with the empty color, the better. In general, white is the bottom and black is the most ideal and safe color combination. The reading beam of a barcode reading device is defined as red light with a wavelength of 633 nm. Therefore, the bar and space reflection performance is reflected by the bar and air-to-red light reflection performance. The bar code symbol bar must absorb red light and have a dark color; On the contrary, it cannot absorb bright red light. Therefore, red can never be stripe, gold can neither be stripe color, nor can be empty color, if there is unreasonable with the empty space in a timely manner with the Commission Printing Unit to modify, to prevent batch scrap.
3. The printing position of the product barcode The position of the product barcode is not deformed by the bar code symbol to facilitate the reclamation principle. The barcode placement position on the commodity packaging is usually printed on the natural bottom surface of the packaging, and any truncation of the height of the barcode symbol of the commodity will be realized. Scanning of barcodes. Therefore, the bar code symbol height is strictly prohibited in principle truncated, left and right blank area size to stay enough, at the same time, there is no character, pattern, perforation or scratches in the blank area, as far as possible away from the edge of the product packaging to meet the Blank area requirements.
4. Decoding correct detection Printing process Before the formal production, it must be tested. The reading equipment scans the bar code symbol. The barrel reads the decoding result is the same as the character for the identification of the person. The sample can be sampled and produced in batches to prevent batch scrapping. . Sometimes it can be read, but when members provide the original film, there is often a phenomenon of multiple yards, one yard and many things...
Third, to strengthen the quality awareness of printing companies to ensure the bar code printing quality, it must be from the leadership, the quality of the vice president, the various department managers and related members of the product quality bar code printing quality leadership group, the organization of quality inspection staff to participate, one employee Self-study to participate in quality management, for the responsibility of each job to clarify the responsibility system for job quality, report to the China Spicy Code Co., Ltd. branch office to review the company, diagnosed and printed bar code qualifications. However, some companies have relaxed their requirements after many aspects of their affairs, and are indifferent to the printing of product barcodes, thereby failing to ensure the quality of the product barcodes.
