| Ink spotting is a common failure of flexo printing machines when printing solid colors, which causes the printed image to look uneven on the surface of the image, with varying degrees of chromaticity and hue, similar to orange peel. Possible causes of the problem and countermeasures: The problem of inaccurate on-site printing also occurs in flexo printing production. Most of the products with higher requirements will pay attention to this matter. The main reason is that the ink transfer of the flexo printing machine is poor. All we have to consider first is to increase the amount of ink transfer, such as appropriately increasing the pressure between the flexo printing machine plate and the substrate, using a lower hardness or higher compatibility printing plate or liner tape to improve Ink transfer condition. In some cases, the viscosity of the flexo printing machine ink may be too low, or the color density may be too low. At this time, the viscosity of the flexo printing machine ink and the balance of the ink additives should be adjusted. Pay special attention to the color density. To improve, it is impossible to only replace the appropriate ink. If the surface condition of the printing plate is not very good, it will also affect the transfer of the ink. For example, the printing plate of the flexo printing machine is not fully cleaned of some residual solvents during the production process, and some oil stains are stained during the use process. It is also possible that the surface of the printing plate is It is not flat (some traditional plate making uses talcum powder particles), then the flexo printing machine plate should be treated first to remove residual chemicals, it is necessary to replace a new printing plate, or appropriately increase the printing pressure to alleviate poor ink transfer Case. flexo printing machine：https://ww w.royal-packings.com /Flexo-Printing-Mach ine | |
