Incorrect design of products is common in beverages, especially in polyester bottled beverages. The shape of the barcode is usually printed on a plastic label. After the label is affixed to the bottle, the shape of the bottle becomes uneven and wrinkles occur. Discounts, resulting in barcode symbols can not be read correctly. In this case, the shape of the bottle should be designed to ensure that the label is smooth.

Bar code printing position is incorrect

In some bags of goods, the bar code symbol is printed near the edge of the bag. Even though the inspection is qualified after printing, after the content is loaded, deformation or wrinkling occurs and the bar code cannot be read correctly. The correct method is to avoid the joints and deformed parts when designing the bar code position. It is better to observe the flat part after loading the content in the bag, and then print the bar code symbol at this position.

In some boxed products, the bar code was qualified when the box was flat. However, when the carton was folded, some of the bar code symbols were masked, or there were insufficient left and right white spaces. This should be fully considered when designing the bar code position.

In order to pursue product upgrades, most products are covered with heat-shrinkable film, which also results in unacceptable barcodes.

After the heat shrinkable film shrinks by heat, it cannot be flattened and crumpled at the corner of the product, and the bar code symbol at this position cannot be correctly read.

Some goods, especially children's goods, are marked with small toys on the heat shrinkable film to attract customers. Commonly, bubble gum puts three-dimensional crystal glue, which often obscures part or all of the bar code symbol, making it impossible to read. .

The labeling of other contents on the product causes the barcode to be unqualified. Commonly, the food is marked with the production date, production batch number, shelf life, etc.:

Labeled incorrectly to the bar code symbol, the boxed food uses pad printing ink, and is marked with a hand-printing machine. Some bar code positions are designed on the other side corresponding to the marked date, and the pad printing ink is printed and changed. It takes a while to dry, and it takes 2 to 5 seconds for the quick-drying ink and 5 seconds for the slow-drying ink. When the box is pushed after the date is marked, the dry ink will contaminate the bar code symbol on the other box, and the amount of contamination will be accumulated to form a stain and cannot be correctly read. This should be taken into consideration when designing the bar code position.

When frozen foods, such as ice cream, are removed from the special products, the surfaces of the frozen foods condense a thin layer of ice due to the low temperature, and the bar code symbol is completely or partially covered, making it impossible to read correctly. These kinds of goods are seasonal and short-term and should use in-store codes.

In short, to ensure the quality of barcode prints, not only must control the process of printing barcodes, but also control the use of barcode prints, only the entire process of printing the barcode until the goods carrying the barcode symbol are sold through the POS system. Attention can effectively promote the improvement of bar code quality.
