Teach You How to Identify the Pros and Cons of Ink for Digital Printing Machine on Metal Sheet

1. Choose excellent shining fastness and weather resistance: Since outdoor inkjet images are fixed in the sun and rain for a long time, ultraviolet rays, acid and alkali, dust and air pollution all cause damage to the image. Therefore, when selecting ink for digital printing machine on metal sheet, please choose a product with a shining fastness degree of 7 or higher and weather resistance degree of 5.



2. Check stability: The principle of ink for UV digital printing machine on metal sheet is that the organic pigment is uniformly fused in the organic solvent system. The low-quality ink can not evenly fuse with the organic solution because of the inferior quality of the raw material, so that the internal structure is easy to be broken up, causing stratification, precipitation, etc. Although this situation can also be solved by shaking with a shaker, when the UV digital printing machine on metal sheet is working, the temperature fluctuates greatly, which still causes the internal structure of the ink to separate and damage the picture.

3. Choose a better-looking hue: The color of the UV digital printing machine on metal sheet depends on the hue of the ink. If the hue of the ink is good, the image drawn by the UV digital printing machine on metal sheet will also be full of color.



4. View the quality of the raw materials: the quality and price of the raw materials also decide the price of this ink. The quality of raw materials includes purity, pH, water content, impurities, etc. These qualities have a great impact on the service life of the nozzle.

5. Detect usability: Good ink for digital printing machine on metal sheet not only easily block the nozzle, but also has a certain maintenance effect on the nozzle, thus avoiding the process of wiping the nozzle, avoiding the wear of the nozzle, and prolonging the service life of the nozzle and reduce the burden of nozzle cleaning.



6. View the technical parameters of ink for UV digital printing machine on metal sheet: Each UV digital printing machine on metal sheet will indicate the type of ink that can be used. Therefore, when selecting ink for UV digital printing machine on metal sheet, please carefully compare the technical parameters and choose Suitable ink. Because only the inks that meet the requirements of the UV digital printing machine on metal sheet can work normally with the UV digital printing machine on metal sheet without causing malfunctions such as clogging the nozzle. So how do we choose for technical parameters that are not marked? Please refer to the regulations.
(1) The printing voltage should not be too high. Otherwise there is no benefit to the nozzle of UV digital printing equipment on metal sheet.
(2) The oscillation frequency should not be too high, otherwise it will not be beneficial to the nozzle of UV digital printing machine on metal sheet.
(3) Low-voltage printing Low-viscosity ink is very suitable for UV inkjet printers.

7. Ink for UV digital printing machine on metal sheet has the characteristics of safety and environmental protection, and has excellent affinity to the environment. Therefore, the ink of UV inkjet printer is not easy to explode, and no accidents harmful to the human body will occur.
