Since the birth of inkjet printers, inkjet printers have used ink as the main product identification carrier to mark products in various industries. Although today, half a century later, the main carrier of inkjet printers is still ink, but after a long time in the development of ink, there have been many improvements, and it has become dry and adherent on the surface of various products. Down the carrier. The progress of ink has become a magic weapon for the inkjet printer industry to achieve marking achievements in various industries. Because the quality of inkjet printer ink is directly related to the quality of marking. And the differences between the connections and products have also become some of the barriers when the inkjet printer is in use, and the ink has often become an important reference to solve these barriers. In different industries, products or packaging are of course different, and even in the same industry, there will be great differences, thanks to the development of the packaging industry. This also means that the medium of the ink will be very different. We clearly know that the ink of the inkjet printer needs to be dried and needs to be fixed. It is basically connected with these media in a form. Therefore, the composition of the ink itself will also have a profound impact on the existence of this relationship. The drying speed of the ink and the form in which the ink responds to these media directly reflect whether the product logo can appear on the product in the expected form, and whether it will normally adhere to the product with the normal use of the product. The marking requirements correspond to the subdivision of ink types and the use of appropriate models when the printer is running. There are also many types of inkjet printers and inks, and cooperation has become an important link in achieving perfect marking.
