Everything You Need to Know About Soy Base Ink and its Benefits

soy base ink

In the pursuit of creating an eco-friendly environment, every little step towards sustainability holds immense significance. The world has already made a significant shift towards adopting eco-friendly packaging solutions. However, it becomes crucial to transition to vegetable oil-based ink, or soy-based ink, to alleviate the strain on non-renewable energy sources further.

By recognizing that every aspect of our actions matters, we can collectively contribute to a greener future. From the smallest details to broader initiatives, embracing sustainability in all its forms is essential. Let us join hands and make conscious choices, ensuring that each component aligns with our commitment to preserving our planet for future generations.

What are Soy-Based Inks?

Soy-based inks are a type of ink made from soybean oil, derived from soybeans. They are an eco-friendly alternative to traditional petroleum-based inks derived from non-renewable fossil fuels.

A Peek into the Production Process

Now, you might be wondering how ink is made? Soy-based inks are made through a process that involves converting soybean oil into a suitable ink formulation. Here is a simplified overview of how soy-based inks are typically made:

Soybean Oil Extraction:

Soybeans are processed to extract soybean oil. This oil serves as the main ingredient for soy-based inks. The soybean oil used should be of high quality and free from impurities.

Modification and Formulation:

The extracted soybean oil is then modified and blended with other ingredients to create a suitable ink formulation. These modifications can include adding resins, pigments, waxes, drying agents, and other additives based on the desired ink characteristics and printing requirements.

Ink Mixing:

The modified soybean oil and other ink components are mixed together in specific proportions to achieve the desired consistency, color, and performance properties. Mixing ensures that all ingredients are uniformly dispersed throughout the ink mixture.

Testing and Quality Control:

The freshly prepared soy-based ink is subjected to various tests and quality control measures to ensure it meets the required standards for viscosity, drying time, color accuracy, printability, and other performance factors. Adjustments can be made to the formulation if needed. Quality control also checks how ink is made.

Packaging and Distribution:

Once the ink passes quality control, it is packaged into containers suitable for storage and transportation. The packaged soy-based inks are then distributed to printing companies, manufacturers, or other users for their printing applications.

It's important to note that the specific process of making soy-based inks may vary among manufacturers.

Benefits of Soy-Based Inks

Soy-based inks offer several environmental benefits:

Renewable Resource:

Soybeans are a sustainable and renewable resource, making soy-based inks more environmentally friendly than petroleum-based inks.

Lower VOC Emissions: 

Volatile Organic Compounds (VOCs) can harm human health and contribute to air pollution. Soy-based inks have lower VOC emissions than petroleum-based inks, improving air quality.


Soy-based inks are biodegradable, meaning they can break down naturally over time. This characteristic reduces the environmental impact of ink waste and minimizes the accumulation of non-biodegradable materials in landfills.

Soy-based inks are compatible with the recycling process. They can be easily removed during the de-inking process, allowing for more efficient recycling of paper and other printed materials.

Print Quality:

Soy-based ink provides excellent print quality and vibrant colors compared to petroleum-based ink. It can be used for various applications, including commercial printing, packaging, and publishing.

Types of Soy Inks

There are primarily two types of soy inks:

1. Conventional Soy Inks:

Conventional soy inks are made using soybean oil as the main ingredient. They are an eco-friendly alternative to petroleum-based inks and offer advantages such as lower VOC emissions, renewable resource utilization, and biodegradability.

2. Modified Soy Inks:

Modified soy inks are a variation of conventional soy inks that have been further enhanced or modified to meet specific printing requirements. Some common types of modified soy inks include:

a). High-Speed Soy Inks: 

These inks are designed to dry quickly, making them suitable for high-speed printing processes requiring fast drying times.

b). UV-Curable Soy Inks: 

These inks are formulated to cure or dry rapidly when exposed to ultraviolet (UV) light. They are commonly used in UV printing and offer excellent print quality and durability.

c). Low-VOC Soy Inks: 

These inks are specifically formulated to have lower VOC emissions than conventional soy inks. They are ideal for environmentally conscious printing applications where reducing air pollution and improving indoor air quality are priorities.

d). Metallic Soy Inks: 

When printed, these inks contain metallic pigments or additives, providing a metallic or shimmering effect. They are often used for specialty printing, such as packaging, labels, or promotional materials.

e). Process Soy Inks: 

Process soy-based inks are formulated to achieve various colors and hues required for full-color printing, such as in magazines, brochures, or catalogs. They offer excellent color vibrancy and are compatible with various printing processes.

Pros of Soy-Based Inks:

An environmentally friendly alternative to petroleum-based inks.

Lower VOC emissions, contributing to improved air quality.

Renewable and sustainable resources derived from soybeans.

Biodegradable, reducing environmental impact, and promoting recycling.

Excellent soy ink printing quality and vibrant colors.

Cons of Soy-Based Inks:

It may require adjustments in printing processes and equipment.

It can be more expensive than conventional petroleum-based inks.

Some formulations may have slower drying times.

Limited availability of specialty or customized soy ink formulations.

Certain applications may require additional additives or modifications.

Overall, the advantages of soy-based inks, such as their eco-friendliness, print quality, and renewable nature, outweigh the potential drawbacks. However, it's important to consider specific printing requirements and potential costs when switching to soy-based inks.
