1. Check whether the ink printed on the machine is the type of ink required by the customer, so as not to cause major printing errors due to incorrect colors.
2. Fully stir the water and ink when you are on the machine. The water and ink will be layered when stored for a long time. You must stir it evenly before you use it on the machine.
3. It is better to add about 10kg of water and ink when you are on the machine, so as not to cause too much water and ink to cause volatilization. If 10kg is not enough, slowly add it to the printing machine.
4. When foaming occurs during printing, you can purchase the corresponding water-based defoamer from the ink supplier and add it appropriately. The general ratio is 1%.
5. When the ink is on the machine, the printing staff should pay attention to the viscosity of the ink is the same as that of the machine, so as not to affect the printing effect.
6. During the printing process, the quality control personnel should strictly control the color. When the color deviation is very small, the printing machine chief can solve it by adjusting the viscosity of the printing machine or the ink. When the color deviation is large, the ink supplier of the ink supplier should be notified to make improvements.
7. When printing, the printing effect is not good, for example: the dot printing is not clear, the font printing is not clear, the overprinting effect is not good, etc., the quality inspection should immediately notify the supplier to solve.
8. The on-machine viscosity of ink must be controlled. Generally, the on-machine viscosity of each printing machine should be recorded, so as to save time when printing next time and reduce paper waste.
