what issues should pay attention to in using ink printing machine
1.Check the ink to prevent the color from causing serious printing errors.
2.Before the machine working make the flexo printing ink agitated completly, because there will be a layer of stratification phenomenon for a long time.
3. When there is a bubble in the printing, you can buy the defoaming performance of water based ink from the ink suppliers. and the general ratio is 1%.
4. When ink on the machine, the printing staff should pay attention to the viscosity of the ink is consistent with that of the machine. so as not to affect the results.
5. The staff should strictly control the color in the process of printing. When there is small deviation, you can be resolved through the ink viscosity, but if the large deviation ,you must be improved by ink supplier.
6. The viscosity of the ink must be strictly controlled, in the general viscosity should be recorded to save time next time, and you can also reduce the waste of paper.
7. Carton factory can also buy some additives to add appropriatly from the ink suppliers. such as wear-resisting agent (to prevent fading), the super imposing agent (to increase the overprint effect).
8. When printing is completed , the ink must be sealed well to ensure that you can use it the next time in order to reduce waste,
