Barcode technology is a widely used method for automatic identification and electronic computer data input in the world, and it is a central printing tool that improves work efficiency. The quality of bar code printed matter affects sales just as the quality of the product itself. Qualified bar code symbols are necessary guarantee materials for the automatic management of POS systems. We have seen that relevant departments have implemented a bar code logo printing qualification recognition system for printing enterprises, and tested the trial printing and formal printing of test products and products to ensure the quality of the bar code printing alliance. However, the situation after this is easy to ignore. Some product barcodes are tested as qualified products after being printed by printing companies. However, during the use of system members and after circulation to merchants, they become unqualified products, which should cause system members ’ Attach importance to central China. There are usually the following situations: Incorrect product design The most common is beverages, especially polyester bottled beverages, and the shape is convex and concave, and the bar code symbol is usually printed on a plastic label. After the label is pasted on the bottle, the shape of the bottle becomes uneven and wrinkled, resulting in a bar code symbol Unable to read the material market correctly. In this case, when designing the shape of the bottle, ensure that the label is printed smoothly in the middle. Barcode printing position is incorrect For some bagged products, the bar code symbol is printed near the edge of the bag. Although the inspection is passed after printing, the content is deformed and wrinkled after being loaded, and the bar code equipment consumables cannot be read correctly. The correct method is to avoid seams and deformed parts when designing the position of the barcode. It is best to observe the flat part of the contents after filling the contents in the bag, and then print the barcode symbol in the middle of China. For some boxed products, the barcode symbol was checked when the packaging box was tiled, but when the carton was folded, the barcode symbol was partially concealed, or the left and right blank areas were not enough in central China. This should fully consider the printing technology when designing the barcode position. In order to pursue the upgrade of products, most products are covered with heat shrinkable film, and there are also printing tools that cause barcodes to fail. After the heat-shrinkable film is shrunk by heat, it cannot shrink and flatten at the corners of the goods, forming wrinkles. The barcode symbol at this position cannot be correctly read in central China. Some products, especially children's products, put a mark between the heat shrinkable film and the product, small toys, etc., to attract customers. It is common to put bubble gum on three-dimensional crystal glue, often covering part or even all of the bar code symbol, making it unreadable Printing tools. If the product is marked with other content and the barcode is unqualified, it is common that the food is marked with the production date, production batch number, shelf life, etc .: It is erroneously marked on the bar code symbol. The boxed food uses a printing ink and is marked by a manual printer. Some boxes have the bar code position designed on the other side corresponding to the marked date position, and the printing ink changes after printing. It takes a while to dry, 2-5 seconds for fast-drying inks, and 5 seconds or more for slow-drying inks. When the box is pushed after the date is marked, the wet ink will contaminate the bar code symbol on the other box, how much pollution is piled up, and the stain is formed, which cannot be correctly read. This should be paid attention to in central China when designing the bar code position. Special quick-frozen foods, such as ice cream, etc., when taken out after refrigerated, due to the low temperature condensed a layer of thin ice cubes, all or part of which covered the bar code symbol, making it impossible to correctly read the printing market. This type of goods is seasonal and short-term, and the in-store code for Central China should be used. In short, to ensure the quality of bar code prints, not only must the bar code printing process be controlled, but also the use process of bar code prints, only bar code printing until the products carrying bar code symbols are sold through the POS system. Only by paying attention can we effectively promote the improvement of barcode quality in the printing market.
