Detailed introduction
1. product characteristics
- The main solvent in the ink is mainly edible alcohol and water;
- Good re-dissolution, anti-crust, anti-blocking version of good, not electrostatic;
- The dot exhibition color is good, overprint color is bright, the level is distinct, especially the shallow net transfer is very good;
- Scratch resistance, abrasion resistance and high temperature resistance on the surface of printed products;
- Suitable speed: 80~250 m/min.
2. applicable substrate
- Biaxial oriented polypropylene (BOPP) surface treatment degree of 38 dyne;
- Polyester (PET) finish up to 52 dynes
- Nylon (NY) surface finish up to 52 dyne
3. diluent ratio
| Name | deionized water | Ethanol |
| quick dry | 20 | 80 |
| Medium stem | 30 | 70 |
| Slow dry | 40 | 60 |
Specific use, should be based on the type of printing machine and specific printing conditions, selection and adjustment.
4. printing viscosity
- White ink (CN3# viscosity cup, 25 ℃):14 seconds ± 5
- Color ink (CN3# viscosity cup, 25 ℃):16 seconds ± 5
Depending on the printing plate depth and speed
5. considerations
- Please stir the ink evenly before use;
- The temperature of the oven shall be controlled at 50 ℃, and the air volume shall be kept at the maximum; the exhaust air shall be fully opened to form negative pressure in the oven;
- Water-based ink requires intaglio graphics part below 35 microns, more than 35 microns will affect the printing speed;
- Adjust the machine speed according to the field environment (air volume, temperature, plate depth), and formulate the appropriate ratio of diluent;
- It is suggested to add 0.6% waterborne curing agent for white large area printing to improve the composite strength and resistance performance;
- Due to the differences in process and printing substrate, please test the adaptability of ink and printing substrate and glue before use.
- Compound according to the actual effect of solvent-free glue or water glue compound;
- When diluting, ethanol and water should be mixed evenly first, and the amount of diluent should be controlled according to the printing requirements;
- The diluted ink and the remaining unused diluent should be fireproof;
- The remaining ink should be sealed in a barrel and stored in a dry and ventilated place to avoid high temperature and exposure.
