Water Based Ink Flexo Printing

Water based ink flexo printing is a flexographic printing technology using water-based ink. Water-based ink is an environmentally friendly, safe and low-cost ink composed of water, pigments, resins, additives, etc. The function of water-based ink is to form uniform, bright and durable images on printing materials, while reducing the emission and consumption of organic solvents, protecting the environment and human health.The quality of Water based ink flexo printing depends on many factors, including ink formulation, manufacturing and storage conditions, performance and adjustment of printing equipment, characteristics and handling of printing materials, printing speed and temperature, etc. In order to ensure the quality of water-based ink, you need to pay attention to the following points:

Choose the right pigment and resin to improve the color strength and stability of the ink
Choose the right additives to adjust ink viscosity, surface tension, drying speed and skinning resistance
Maintain a constant temperature and pH of the ink to prevent delamination, solidification or deterioration of the ink
Regular cleaning and maintenance of printing equipment to prevent ink clogging or contamination
According to the surface energy and absorbency of the printing material, select the appropriate printing plate and pressure to ensure the clarity and sharpness of the image
Control printing speed and drying temperature to ensure uniform and fast drying of ink

sustainability:

Furthermore, the utilization of water-based inks adds to enhanced sustainability. These inks are ecologically degradable and impose a reduced toll on the environment throughout both the printing and disposal phases. This concurs with the escalating desire for more environmentally-friendly technologies and lends backing to corporate endeavors towards social responsibility.

versatility:

Another significant benefit of water-based ink printers lies in their versatility. They exhibit compatibility with an extensive array of media varieties, encompassing paper, cardboard, fabric, and even specific plastics. This inherent adaptability renders them fitting for a myriad of purposes, including the creation of marketing collateral, educational materials, packaging, and textile printing.

FAQ

How to choose the right ink for my product?

Choosing the right ink is very important for the quality and effect of flexographic printing. Different inks have different characteristics and scope of application, which need to be selected according to printing materials and printing conditions. Here are some basic principles for choosing inks:
Consider the surface tension of inks and printed materials. The ink should have a lower surface tension than the printed material in order to flow and wet on the printed material. Generally speaking, water-based inks are suitable for printing paper or cardboard with strong absorption, and solvent-based or UV inks are suitable for printing plastic films or metal foils with weak absorption.
Consider how and how fast the ink dries. Water-based ink is mainly dried by water evaporation, which requires higher temperature and longer time, and is suitable for low or medium speed printing. Solvent-based ink is mainly dried by solvent volatilization, which requires lower temperature and shorter time, and is suitable for high-speed printing. UV-type ink is mainly dried by ultraviolet radiation, which requires special equipment and faster speed, and is suitable for high-quality and high-efficiency printing.
Consider the environmental protection and safety of the ink. Water-based inks are the most environmentally friendly and safe inks because they contain no organic solvents, produce no harmful gas or odor, and will not cause fire or explosion.
