2. Ink should be purchased directly from equipment buyers, not from unknown channels, to avoid nozzle blockage and print quality degradation caused by purchasing inferior ink.

3. When using transfer printing ink, transfer printing paper should use high-quality paper to avoid product quality degradation due to poor transfer printing performance of paper.

4.UV ink should be used with UV curing lamp. The power of UV curing lamp should not be too high or too low. It is best to ensure that the printing medium is not deformed and the UV ink is cured firmly after printing.

5. If the equipment is not used for printing for a long time, the ink generated in the equipment will precipitate. Before using the equipment, the nozzle should be cleaned, and if necessary, the entire pipeline of the equipment should be cleaned with special cleaning solution, and all the ink in the first-class ink cartridge should be replaced.

If the bottle is found to be out of date or the bottle mouth is not sealed clearly, contact the ink supplier in time to determine the ink quality.
