Cement products are everywhere in our lives, such as houses, roads, bridges, telephone poles, flower beds, floor tiles, etc., all made of cement. They are large in size and rough in surface. They need their own numbers in use, which is convenient for installation and statistics during use. How to print these numbers? Traditional cement products are realized by spray painting with fonts. The disadvantage is that you need to prepare a lot of fonts and the content should not be too complicated. Because the font is large, the amount of paint is also large. The more complex the text content, the more complicated the logo of the cement product. Based on the complex characteristics of the formation process of spray paint for cement products, enterprise users are also in urgent need of better marking solutions. The emergence of handheld inkjet printers has brought a lot of convenience to large-volume product identification. Shenyang Oulance inkjet printer manufacturers have professional handheld inkjet printers for cement product identification. Compared with traditional methods, handheld inkjet printers have enriched the content of large-volume product inkjet coding: 1. It is richer in content, including numbers, letters, Chinese characters, special symbols, two-dimensional codes, barcodes, and graphics, whether it is simple coding or The beautifying graphics are input into the handheld inkjet printer through the electronic version of information, and directly sprayed on the product, saving the link of customizing the font; second, the inkjet printer consumables are more economical, and the cost of each product identification is reduced For enterprises, it not only improves the aesthetics of products, but also reduces the cost of their products. The application of new technologies and new methods in the industry also raises the height of the enterprise. Third, the use of hand-held inkjet printers to identify product information and code assignments has achieved greater convenience, especially the identification of variable information (two-dimensional code), which makes it possible to identify one item and one code information on large items.
