SOY INK Eco-Friendly Printing Ink
Soy ink, as the name suggests, is a printing ink made from soybeans. It was invented and developed in the 1970s by the National Newspaper Association (NNA) in the United States. At that time, the goal of creating soy ink was to reduce the use of petroleum-based inks, which had a significant negative impact on the environment.
The NNA began experimenting with vegetable oil-based inks, and soybean oil was found to be the most suitable for making printing ink. Soybeans are easily renewable, spread ink well, and at that time, there was an oversupply of soybeans in the American market, making the raw material easily accessible and affordable.
Benefits of SOY INK
Since its development in the 1970s, soy ink has proven itself to have numerous advantages beyond just being an alternative to petroleum-based ink. Especially for printing on food-related items, soy ink is an excellent choice. Here are some of its many benefits:
1. Environmentally Friendly
Soy ink is made from soybean oil, which is a renewable resource, unlike petroleum, which is finite. The production and extraction processes of petroleum ink release greenhouse gases, so reducing petroleum use and switching to soybean oil is more environmentally friendly.
2. Vibrant Colors
Soy ink, made from soybean oil, spreads color exceptionally well. This makes prints with soy ink more vibrant and clear than those with conventional inks. It is also suitable for high-quality printing that requires long-lasting colors.
3. Easy to Recycle
Recycling paper after use is common, but did you know that removing ink from paper before recycling is easier with soy ink? Paper printed with soy ink is easier to de-ink than paper printed with petroleum ink. This means it can be recycled more easily, using fewer chemicals and less energy, making it more eco-friendly.
4. Safe for Health
Soy ink has low levels of volatile organic compounds (VOCs), which can cause serious health problems if inhaled regularly over time, such as respiratory issues and allergies. Using soy ink with low VOC levels is safer for users. Additionally, soy ink is food-grade, making it safe for printing on food packaging without worry.
Drawbacks of SOY INK
Although soy ink, made from soybean oil, has many wonderful benefits, it also has limitation and drawbacks. Understanding these can help you decide if soy ink is the right choice for your printing needs. Here are some of the disadvantages:
1. High Cost
Printing with soy ink results in higher quality prints compared to regular ink, but it comes with a higher cost. The production process of soy ink is more complex and difficult than that of regular ink, leading to higher expenses.
2. Slower Drying Time
After printing with soy ink, the ink takes longer to dry compared to conventional inks. This slower drying time may not be suitable for printing jobs that require quick drying because soy ink does not contain volatile organic compounds.
3. Limitations
There are certain limitations to using soy ink. For example, it is not suitable for printing on plastic, using in small home printers, or for use in ballpoint pens.
What are VOCs ?
In the section "Benefits of Soy Ink," VOCs are mentioned, but many people might not know what VOCs are. Volatile Organic Compounds (VOCs) are chemical compounds that easily evaporate at room temperature. They can be found in many industrial products, including printing ink. These volatile compounds can harm both health and the environment.
Health Effects
VOCs are chemicals that can evaporate into the air and be inhaled by humans. Breathing in a large amount of VOCs can irritate the respiratory system, eyes, nose, and throat. In the long term, it can cause chronic diseases like cancer. Additionally, some people may experience allergic reactions and skin problems.
Environmental Impact
VOCs released into the air can cause air pollution and contribute to the greenhouse effect, which leads to global warming and climate change. Reducing VOC levels in products is important to minimize environmental impact.
"Soy ink, with its low VOC content, is a good choice for reducing health and environmental impacts. It is a great option for those who want their printing processes to be more sustainable and safer."
"From this entire article, we can conclude that soy ink is an innovation that truly benefits the environment and health. It also offers advantages like better color distribution, resulting in high-quality prints. Despite its limitations, such as higher cost and slower drying time, understanding the pros and cons of soy ink will help you decide if it is suitable for your printing needs."
