What problems should be paid attention to when using ink and wash?
1. Check whether the ink printed on the machine is the ink required by the customer, so as to avoid serious printing errors caused by incorrect colors.
2. Fully stir the ink when you use the machine, the ink will be stratified when stored for a long time.
3. When foaming occurs during printing, you can purchase the corresponding water-based defoamer from the ink supplier to increase it. The general ratio is 1%.
4. When the ink is on the machine, the printer should pay attention that the viscosity of the ink is consistent with the viscosity of the machine on the machine, so as not to affect the effect.
5. In the printing process, the staff should strictly control the color. If the color deviation is small, it can be solved by the ink viscosity. When the color deviation is large, it should be improved by the ink mixer of the ink supplier.
6. The upper machine viscosity of the ink must be controlled. Generally, the upper machine viscosity of the printing machine must be recorded, so as not to save time in the next printing and reduce paper waste.
7. The carton factory can also purchase some related additives from the ink supplier, such as anti-wear agent (used to prevent color fading) and superimposition agent (to make the overprinting effect good) and add them appropriately.
8. After the printing is completed, the ink taken down must be sealed to ensure that it is used in the next printing to avoid reducing waste.
