At present, inkjet printers have almost become necessary equipment on the production line of various industries. For customers who need machines, it is very important to choose the corresponding technology and ink to design inkjet solutions that meet their own production materials and production environment. However, Food safety is the top priority. The Arnoldage brand online food packaging inkjet printers print a wide variety of content: the inkjet printer supports printing text, numbers, pictures, one-dimensional barcodes, two-dimensional barcodes, and Hanxin codes. , Drug supervision code, GS1-DataBar/RSS and composite bar code, garbled code, database, picture database, etc. 1.

For products that will be packaged immediately after coding, the drying time of the ink is particularly important. Quick-drying inks can be selected, or air blowing can be used The device speeds up the drying of the ink. 3. It is suitable for severe production environment and strict hygiene requirements. Food manufacturers must consider the performance of high humidity and high dust resistance when choosing inkjet printers. Therefore, the stainless steel construction of the inkjet printer is often necessary.
