Problems solved by technology

The printing of bills has its particularity, because the paper used for printing bills is very thin and smooth, so on the one hand, it is easy to send multiple sheets of paper into the printing department for printing at the same time, resulting in blank pages or incomplete pages in the final product pages; on the other hand, it is difficult to neatly stack the printed bills, requiring manual alignment, reducing production efficiency

In addition, due to the special function of bills, there is a high requirement for the position of the printed pattern on the bill. Once the paper entering the printing department is tilted, the pattern will not appear in the center of the paper, which will affect the quality of the product.
