Five, matters needing attention:
|
No. |
Matter | Key points |
|
1 |
Stir before use | It should be fully stirred before use to make the ink have good fluidity. |
|
2 |
Avoid mixing | Our ink system is unique and cannot be mixed with other types of ink to avoid unnecessary losses due to incompatibility. |
|
3 |
Oven conditions | 1. Ensure that the air inlet and exhaust of the oven are large, the exhaust system is normal, and a negative pressure environment is formed in the oven (the hot air in the oven cannot be blown onto the printing plate) to ensure that the humid water vapor is quickly discharged; 2. The oven temperature is set at 55 Above ℃, the temperature should be adjusted as high as possible within the range that the printing substrate can bear to facilitate the drying of the ink. |
|
4 |
Prevent blockage | 1. The hot air of the oven can not be blown onto the printing plate to avoid the ink drying and blocking the plate; 2. Please keep the plate roller rotating in the ink tank when replacing the substrate or temporarily stopping the machine; 3. During the printing process, if the plate is stopped for a long time and then turned on again, the plate roller can be rotated in the ink tank for a few minutes, and the printing plate can be wiped with solvent or ink in the ink tank to continue printing. |
|
5 |
Plate roller cleaning | After printing, please clean the plate roller with ethanol and brush with anti-rust oil for normal use next time. |
|
6 |
Ink Recycling | After printing, put the remaining ink in a clean plastic bucket. The mouth of the bucket must be sealed and filtered when it is reused. |
The above data is only obtained by our company. Depending on the materials used and processing conditions, the results will not be the same, please confirm before using.
6. Storage and packaging:
Storage: Store in a ventilated and cool place (-5°C to 35°C), sealed and stored, protected from fire and sun, avoid rain and pollution. The shelf life is one year.
Packing: plastic barrel, 18KG/barrel, 20KG/barrel, 25KG/barrel, 50KG/barrel.
