1. Introduction of product features:
Alcohol gravure ink series is specially used for cigarette pack printing ink, suitable for all kinds of paper substrates. The product is made of nano-scale inorganic pigment, special modified alcohol-soluble resin and related additives by dispersion grinding. The product has excellent resolubility, excellent overprint and leveling, wear resistance, scratch resistance, anti-adhesion, drying and printability is excellent; The product is non-toxic, low-odor, non-flammable, no heavy metal and VOC content, no safety risks, and fully meets the standard requirements of cigarette pack safety substances.
Two: Technical parameters:
item | Parameter standard | item | Parameter standard |
Appearance: (visual) | Benchmarking sample | Solid content: (weight loss method) | 30~34% |
Viscosity: (2# cup /25℃) | 30s~35S | Fineness: (scraper fineness meter) | <15um |
Adhesion: (3M tape) | 100% non-pulling | Leveling property: | better |

Three: Use process:
1, printing method: A, concave printing: (ink viscosity dilution to 16-22S).
B, single concave printing: (ink viscosity dilution to 24-28S).
2, printing speed: according to the drying temperature and time conditions, the printing speed is controlled at 120-200 meters /min.
3, drying method: infrared drying: drying temperature at 90℃-105℃(drying conditions will affect the printing/coloring/adhesion of the ink).
Four: Precautions:
1. The printing effect of alcohol-soluble gravure ink is related to the printing substrate used, working environment, time and temperature, etc. Please ensure that the printing is fully dry; Ensure the stability of the above printing conditions. Otherwise, it will affect the surface quality requirements of the printed product.
2, the ink must be fully stirred before use to ensure color stability and good fluidity; The viscosity of the ink thickens during use, and it can be diluted according to the mixture of "anhydrous ethanol + n-propyl ester according to 4:2". The dilution amount is based on the viscosity requirements.
3, accidentally contact the product on the skin or splash into the eyes, please wash immediately with water.
4. This product should be stored in a cool and ventilated place, away from high temperature.
