Background technique

Labels are used to mark your product goals and categories or content, such as the keywords you have determined for your goals, which are tools for you and others to find and locate your goals. Most of the labels in the printing industry are Printed materials used to identify the relevant instructions of their own products, and most of them are self-adhesive on the back, but there are also some printed without adhesive, which can also be called labels. Labels with adhesive are commonly known as "non-drying Glue label", the label problem after the instrument is calibrated, this is a label that is uniformly regulated by the country (or its own province). The development has naturally promoted the development of label printing technology. Label printing covers all printing methods such as flat, convex, concave, and net. The application conditions in different countries are not the same. However, it can be seen from the development trend of global labels in recent years. Flexographic printing, narrow web printing, and digital printing have become new highlights in label printing in European and American countries, and they are also the development trend of label printing.

The existing technology has the following deficiencies: the existing front and back inkjet labels are all printed on one side, and then the other side is printed after the inkjet printing on one side, so that the printing efficiency of the label is very high. At the same time, after the inkjet printing of the existing labels is completed, some unqualified labels are manually marked and picked out of defective products, resulting in cumbersome production process efficiency and average label quality.

Therefore, it is necessary to invent a production process for the front and back inkjet labels.
