Technical Guidelines & Operating Instructions

Follow these recommendations to achieve optimal printing results and ink performance.

Core Process Parameters

Standard Viscosity: 20-30 seconds (Zahn 4# cup)
pH Control: 8.5 - 9.5
Substrate Requirement: Surface Tension ≥ 38 dyne

Operating Recommendations

Dilution Ratio:

Suggested water addition is less than 10%, depending on ambient temperature and humidity.

Anilox Roller:

Recommended 400-600 line screen for optimal ink transfer.

Drying Temperature:

Set dryer between 60℃-80℃

Machine Stoppage:

If stopped for more than 30 minutes, flush the ink path thoroughly with water.

Important Warning: Do not over-reduce with water. Excessive water addition will cause viscosity breakdown and adhesion failure. For drying speed adjustments, please consult technical support for specialized additives.

FAQ for This Water-based Ink

Q1. What is water-based flexographic ink and what materials is it suitable for?

A1: Water-based flexographic ink (such as SC8100) is an environmentally friendly ink that uses water as the main solvent, specifically designed for flexographic printing on flexible packaging. It is widely applicable to various plastic films, including PE (polyethylene), PP (polypropylene), PET (polyester), and BOPP (biaxially oriented polypropylene). It is suitable for printing on food packaging, pet food, beverage labels, aluminum foil seals, hygiene products, and non-woven bags.

Q2. Does this water-based ink comply with international environmental and safety standards?

A2: Yes, the SC8100 water-based flexographic ink strictly complies with multiple international environmental and food safety standards. It has passed FDA 21 CFR 175.300 (US food contact material certification), ROHS 2.0, and the EU REACH SVHC 253 high-concern substance test. The product is non-toxic, non-flammable, and has a VOC content of less than 1%, making it a green printing solution with low emissions and high safety.

Q3. What are the performance advantages of using this water-based ink?

A3: The SC8100 features high concentration and low viscosity, offering vibrant colors and excellent leveling properties for superior printing results. It boasts strong adhesion, excellent rub resistance, and fast drying speeds, supporting high-speed continuous printing at 150–400 meters per minute. Additionally, the ink is water-dilutable and easy to clean, reducing solvent consumption, lowering production costs, and enhancing operational safety.

Q4. What are the solid content and printing speed of the ink?

A4: The solid content of this water-based ink ranges from 30% to 40%, making it suitable for high-concentration formulation. The printing speed can reach up to 400 meters per minute, compatible with medium-to-high-speed flexographic printing equipment, meeting the efficiency and stability requirements of large-scale industrial production.

Q5. What is your delivery time?

A5: We have an efficient production and logistics system and can deliver quickly based on order volume: Orders under 1 ton: Delivery the next day Orders under 5 tons: Delivery within 3 days Orders under 20 tons: Delivery within 7 days Specific delivery times will be confirmed based on the final order.
