How to choose and use barcode printers correctly?

With the industrial upgrading of industrial packaging, barcode, two-dimensional code and other types of coding methods are becoming more and more common, and the application of barcode inkjet printers is also increasing, especially on the surface of some permeable materials and some food, beverage, and Japanese products. There are more applications in cosmetics, carton packaging boxes and other products, so how to choose and use barcode printers correctly? Today, Qianli will share some knowledge in this area with you. 1. What are the types of barcode printers? This problem is the first one that needs to be solved. For example, the bar code printing effect in the picture above, the material is paper packaging, the resolution of the bar code is good, the scanning rate is high, the scanning speed is fast, and the bar code like this is printed, We need to use high-resolution inkjet printers (high resolution), the common ones are thermal foam inkjet printers (HP printheads), and there are also high-resolution printers with Xaar printheads. The difference between the two lies in the height of the print information. The height of the HP printhead barcode printer with a single printhead is 12.7mm, and the Xaar printhead barcode printer with a single printhead of 17.3mm. Each has its own advantages and disadvantages. , HP print heads are more expensive, but they are easy to use, more flexible, and have strong operability; Xaar print heads can be reused, and the use cost is low, but the operation is relatively troublesome, and the ink bag needs to be replaced. In addition to high-resolution machines, there are also small-character machines and laser marking machines. The small-character barcode printer has a faster printing speed, and can achieve a high-speed online code assignment of 100m/min at the fastest; bar code The laser machine can achieve a higher level of anti-counterfeiting function. The laser forms the non-erasable and modifyable content information on the product surface, which can be stored for longer and the information content is more durable. 2. Different types of barcode printers need to be selected for different material surfaces. As we can see from the above picture, the character effect formed on the surface of different materials is different, and the adhesion is also different. Here we will mention the ink type and selection instructions of the barcode printer. Generally, it is on the surface of metal or plastic. Choose a quick-drying type of ink. Taking Kinglee Q550 small character inkjet printer as an example, the drying time of ordinary black ink is 0.3 seconds, which can be dried quickly and adhesion. We generally produce according to the customer's process requirements, such as whether it needs alcohol wiping, high temperature, freezing, etc. For some bottled products, such as the olive oil industry, we will select inks that can penetrate the oil for testing to improve the accuracy of a successful one. 3. What should be paid attention to when using the barcode printer? Scan rate. The printed barcode generally contains a lot of content, such as English, digital, Chinese and other information transmission. If the scanning rate is not reached, the entire product will not be recognized, which will affect the product quality and customer identity. In response to the above situation, relying on rich experience in the automated marking industry, we can quickly provide customers with targeted automated marking overall solutions, such as visual inspection and CCD printing positioning, so that the printing effect is more accurate and the scanning rate is guaranteed. When the scan fails, the reject device is used to reject the product to ensure that qualified products flow out, and then targeted optimization adjustments are made according to the data feedback to improve the yield. Daily cleaning, such as cleaning the surface of the machine after get off work, tidying up and rectifying the working environment, the temperature and humidity of the environment must be within a reasonable range, and the ground wire must be connected to prevent electrostatic interference from causing equipment abnormalities. maintenance. In the process of using, no matter what model or type of machine, we must not forget to maintain and maintain. This is very important. In order for the inkjet printer to have a better printing effect and achieve the expected service life, Routine maintenance must be carried out to keep the whole machine in a healthy state of operation whether it is the ink circuit system or the circuit system.
