By proofing and detecting the barcode identification of the sample, various problems existing on the printing plate can be discovered in time. According to the severity of the problem, it can be corrected by means of trimming, adjusting the parameters of the printing plate, and making a plate.
The proofing work is generally performed on a proofer, and a printing company without a proofer can print a small amount on a printing press.
(2) Print Control
Off-site printing bar code labels have a large amount of time and a long time. Therefore, printing companies must strengthen the quality control during the printing stage so as to avoid economic losses caused by quality accidents.
The printing crew should be familiar with the basic theory of bar code, master the printing technology and printer performance. Ensure that the printer is in normal operation before starting up.
The printing crew should monitor the random status of the print carrier, media, and equipment and eliminate various hidden dangers and failures in time. Control the quality of bar code markings by ink volume, press pressure, temperature, etc.
During the transfer of flight crews, each other should be notified of the status of equipment and the problems in the printed products, so as to ensure the quality of the printed products in each shift.
Quality inspectors shall randomly sample inspections on the production line and provide feedback on flight crew members in a timely manner. For the initial printing of printed products, the quality inspection personnel should also increase the frequency of sampling.
In addition to enhancing the training and assessment of printing crews, and improving their printing technology and the ability to control the quality of bar code labels on site, leaders of printing companies should also provide bar code printing workshops with suitable working environments and facilities.
The working environment is a combination of human factors and physical factors, such as temperature and humidity in the workshop, hygiene conditions, light, noise, vibration, odor, and air cleanliness, which can directly affect the operator's subjective initiative, satisfaction level, work style, and job performance.
The leaders of the printing shop should also coordinate the use of printing machinery, the placement and handling of semi-finished products and finished products, and the non-pollution of printed products during multiple off-line and off-line processes.
(3) Postpress control Postpress control includes product inspection control, product storage control, and product shipment control.
a. Finished product inspection control
1. The quality inspection personnel's printing companies must effectively control the quality of quality inspectors. Through examinations, examinations, walnuts are selected with responsibility and strong principles, and trained by bar code theory and testing methods of coded institutions, and quality inspectors who are familiar with the bar code national standards serve as bar codes. Identify the finished product inspection work.
Bar code inspectors should understand the sampling method and quality judgment of the batch printing bar code identification, and strictly implement the “Barcode Print Quality Inspection System†to ensure that the inspection level is standard, the inspection data is complete, the inspection method is scientific, and the sample and inspection records are complete.
2 Inspection Instruments Barcode detectors are indispensable for quality identification of bar codes. Bar code stripe, empty reflectivity and contrast, decoding correctness, stripe size error, inspection code are all detected by barcode detector. Therefore, printing companies should actively and actively configure the barcode detection instruments.
Before each test, it must be ensured that the bar code detector is in a normal state. Correctly input various parameters according to the different barcode prints and the requirements of the barcode detector.
3 Inspection methods The inspection methods are listed in the National Standard GB/T “Inspection of Product Bar Code Symbol Printing Qualityâ€.
b. Product Storage Control Warehouse management personnel must strictly implement the “Warehouse Management System.†When the product is placed in the warehouse, it must check the name of the barcode print, the manufacturer identification code, the product item code, the product certificate, the barcode identification inspection certificate, and the registration And according to the quality level clearly identified, classified placed.
The printed matter with unqualified waste or bar code identification is strictly separated from the qualified product, and no confusion is allowed. After the agreement is obtained through consultation with the user, the user can obtain agreement and then destroy or do effective technical treatment.
Warehouse management personnel should do moisture-proof, dust-proof and fire-proof work on the warehouse site to avoid distortion or loss of barcode identification.
b. Product control
Barcode print is the product of the printing company. Unqualified bar code prints will flow into the market. Once discovered, the quality and technical supervision department may impose severe penalties in accordance with Article 33 of the "Regulations of the People's Republic of China on Standardization Implementation."
Printing companies should strictly control the manufacturing process of products. It is forbidden to leave the factory with incomplete procedures or unqualified bar code inspection.
The name of the bar coded printed matter, the manufacturer identification code, the product item code, the variety, and the quantity to be delivered to the user must be correct and the quality conforms to the requirements of the national standard and the user's contract.
