At present, my country's timber and wood products market does not have standardized management, and the phenomenon of counterfeit and inferior products is still relatively serious. Consumer complaints about the quality and after-sales service of wood and wood products are also increasing, which not only brings economic losses to consumers, but also has a negative impact on the entire wood and wood products industry and associations. For this reason, relevant departments have designated 'Commercial Timber and Wooden Products Marks' for timber and wooden products, which facilitates the traceability of fluids and wooden products on the market, rectifies and regulates the order of the timber market, and safeguards the legitimate rights and interests of consumers and enterprises. So for the wood industry, template painting is basically used, which is time-consuming and has a relatively high fault tolerance rate. Frequent rework increases the manpower and material resources of the company. Hand-held inkjet printers undoubtedly bring perfect marking applications to the wood industry. . Because most of the wood products are relatively large in size and inconvenient to move and have different shapes, the portable inkjet printer has super battery life (50 hours of continuous work on a single charge), and can be perfectly printed on different surfaces, avoiding manual marking Misprints and omissions caused by this. Taking into account the long-term use and operation, the handheld inkjet printer is designed according to ergonomics in appearance, which is easy to operate and carry, has a good grip, and is not prone to fatigue after long-term use. Wood and wooden products often need to face the sun and rain. Ordinary inks are easy to fade and shift outdoors for a long time. The portable inkjet printer uses quick-drying ink to ensure that the logo content of wooden products is effective and highly recognizable for a long time. Taking into account the diversity of printing environments, temperature differences and harsh environments are likely to affect the nozzle clogging, the inkjet group has made high standards for every component, and the nozzle has the characteristics of wear resistance / high temperature resistance / corrosion resistance, regardless of In any environment, ensure that the nozzle will not be clogged, the marking content is stable and clear, and the content is clean and tidy.
