For multi-process small and medium-volume order label products, most letterpress printing machines cannot meet the production requirements of these complex multi-processes at one time. If the production process is separated, the time period is too long, the production equipment is too much, and the production cost is too high. Due to the market positioning relationship, the early letterpress printing machine could not load more module functions at present, and it was impossible for the end customer to add the function of modifying the application module to the current letterpress printing machine, otherwise the equipment cost was higher. Therefore, most of the letterpress printing is only a common process label product that satisfies the functions of spot color + four-color printing + glazing + die-cutting machine waste discharge. With the development and demand of technology, the new PS version intermittently sold on the market. The printing machine also has a unit module that increases cold foiling, and the cost is increased by 250,000 to 300,000.

With the development of technology, the label digital printing machine appeared in the market, which is a supplement to the small orders in the label industry. At present, the label digital printing machine is mainly divided into two types: electronic ink transfer to the substrate technology through the blanket and direct inkjet technology of the print head.

The current market is mainly based on the single-label sales of the label digital printing machine, which only includes the rewinding and unwinding unit, the corona module, and the digital printing machine. There is no integrated pre-press and post-production processing module, just to do the digital printing + post-processing integration unit for the customer. Solution quotation requires third-party partners to integrate the downstream processing module. The post-processing integrated unit module includes a glazing unit, a laminating unit, a cold-blowing unit, a die-cutting and cutting-discharging unit, and the price is similar to that of a label digital printing machine, which is expensive. Therefore, most of the purchase users only buy the label digital printing machine, and do not purchase the post-processing integration unit, so the digital label printing machine only satisfies the white ink + color printing, and finally the printed label finished product is then made offline full version glazing/covering. The film and die-cutting are cut and discarded, and finally the finished product is obtained. For the user, although the digital printing of the label satisfies the rapid printing without the plate, it cannot meet the requirements of one-time printing, glazing, laminating, cold-scaling, die-cutting and cutting, and the production process is long. It involves the production and processing of other process personnel, so digital label printing does not reduce the real time and production costs for users.
