A new regulation will be established for commodity barcodes. Six categories of commodities must have barcodes. When sold in malls or supermarkets, barcodes are like commodity ID cards. Commodity barcodes are generally printed on commodity packaging, or made into barcode labels and attached to commodities. For small batch products, barcodes can also be printed on stickers. Printing on commodity packaging generally uses coding machines and inkjet printers. The commonly used equipment for attaching barcode labels to commodities is labeling machines. Currently, ribbon coding machines, pneumatic coding machines, and ink wheel coding machines are mainly used in the market. They all have their own differences! Ink-wheel coding and printing are more frequent and wide-ranging, such as some small companies will use it. The reason is simple: the price is the most affordable. Its disadvantage is that the adhesion is not strong! And the ribbon coding. The price is more expensive than the ink wheel, the printing is better, and it is more difficult to wipe, and the clarity is acceptable! If there is an oily food belt, the printing effect will not be very good! Speaking of inkjet printers, it may be the best machine in this industry. Its consumable is inkjet printer ink, which has very strong adhesion and clear writing, but the cost of machinery is high! Generally, small companies don't need it. The inkjet printer is a device that is controlled by software and uses a non-contact method to mark the product. In terms of work patterns: one type is online inkjet printers, which are mainly used for assembly lines; the first type of mobile inkjet printers is that the object to be sprayed does not move and the coding is mobile, similar to the handheld inkjet printers on the market. .
