Why is water based ink better?

Date:2024-06-02  From:Star Color   


Water-based ink, a gradually popular environment-friendly ink in the printing industry in recent years, possesses numerous advantages over traditional oil-based ink in terms of environmental protection, safety, performance, and cost-effectiveness.

  1. Environmental Protection

Reduction of Volatile Organic Compounds (VOCs)

Traditional oil-based ink contains a large amount of volatile organic compounds (VOCs), which volatilize into the air during use, causing environmental pollution and potential harm to human health. Water-based ink uses water as the main solvent, significantly reducing VOC emissions. Therefore, using water-based ink helps reduce air pollution and meets increasingly stringent environmental regulations.

Biodegradability

Most of the components in water-based ink are biodegradable, meaning that they will not have long-term negative effects on the environment after disposal. In contrast, some components of oil-based ink may persist in the environment for a long time, making them difficult to degrade and causing persistent pollution.

  1. Safety

Reduction in the Use of Hazardous Chemical Substances

Water-based ink mainly consists of water and some water-soluble resins, basically free of harmful chemical substances such as benzene and toluene. It does not release toxic and harmful gases during use, reducing health risks for operators and improving workplace safety.

Fire and Explosion Resistance

Water-based ink's main component is water, which is non-flammable and poses no risk of fire or explosion. In contrast, oil-based ink contains a large amount of organic solvents, which are flammable and explosive, posing higher safety risks.

  1. Performance

Printing Quality

Modern water-based ink, through technological improvements, can provide printing quality comparable to oil-based ink. It has good adhesion and vivid colors, enabling high-quality printing on various substrates. Additionally, water-based ink dries quickly, making the printing process more efficient.

Wide Range of Adaptability

Water-based ink is suitable for multiple printing techniques, including offset printing, gravure printing, flexographic printing, and screen printing. It exhibits good compatibility on different types of printing equipment, meeting diverse printing needs.

  1. Cost-effectiveness

Raw Material Cost

Water-based ink's main component is water, making it relatively inexpensive. Additionally, as environmental regulations strengthen, oil-based ink may incur additional costs for environmental treatment. In contrast, water-based ink has lower environmental treatment costs, making it more economical overall.

Reduction in Waste Rate

Due to water-based ink's higher stability and consistency, the waste rate during printing is lower. This reduces production costs and improves economic benefits.

In summary, water-based ink outperforms traditional oil-based ink in terms of environmental protection, safety, performance, and cost-effectiveness. Its advantages include reduced VOC emissions, improved biodegradability, reduced use of harmful chemical substances, fire and explosion resistance, enhanced printing quality and adaptability, and lower costs. With technological advancements and increasing environmental awareness, water-based ink is expected to gain wider application and promotion in the printing industry in the future.
