Can the ink solvent still be used after it has expired?

If the ink solvent exceeds its shelf life, adverse chemical changes will occur, such as: 1. The conductivity is reduced, the ink droplets cannot fully absorb electricity, and the printing is intermittent; 2. Cause the formation of insoluble impurities, block the ink path and nozzle of the inkjet printer; 3. The viscosity of the ink changes, aggravates the blockage, and the printer fails and stops. These changes can cause reliability issues with the printer and also lead to a deterioration in print quality. Due to the unpredictable nature of these changes and their potential harmfulness, they can affect the performance of the printer and accelerate the aging of the printer. Therefore, do not use inks and solvents that have exceeded their shelf life.
