ECO-Solvent Ink is a new type of ink that conforms to the trend of green development, showing unique advantages in composition and performance. From the perspective of composition, it abandons the highly volatile and toxic organic solvents in traditional inks, and instead uses green solvents such as vegetable oils and alcohols to reduce the harm to the environment and the human body from the source.
In terms of performance, the drying speed of environmentally friendly solvent ink is fast, which can adapt to the needs of high-speed printing and greatly improve production efficiency. Its color expression is also excellent, both the saturation and delicacy of the color are remarkable, and it can accurately restore various patterns and texts to meet the printing requirements of different scenes. In addition, this ink has good compatibility with various printing substrates, whether it is paper, plastic film or metal sheet, it can achieve firm adhesion, and the printed pattern has good wear resistance and corrosion resistance, and is not easy to fade and fall off. With the characteristics of low pollution and high performance, environmentally friendly solvent inks are widely used in food packaging, label printing, publication printing and other fields with strict environmental protection requirements, which not only ensure the printing quality, but also fit the current concept of sustainable development, and become an important help for the transformation and upgrading of the printing industry.
1. The working principle
The work of environmentally eco-solvent inks is based on the principle of solvent volatilization, drying, and film formation. Inks are mainly composed of pigments, environmentally friendly solvents, resins and additives. When printing, the ink is transferred to the surface of the substrate through the printing equipment. Subsequently, the environmentally friendly solvent is gradually detached from the ink system by virtue of its own volatility, so that the resin and pigment and other components are cross-linked and solidified, forming a firm and colorful ink film on the surface of the substrate. Different from traditional inks, the solvents used in environmentally friendly solvent inks are green and environmentally friendly, which not only has a reasonable and controllable volatilization rate, but also effectively reduces the negative impact on the environment and the health of operators.
2. How to use
Equipment adaptation
According to the printing process and equipment type, choose the matching environmentally friendly solvent ink. For example, different printing methods such as offset printing, gravure printing, flexo printing, etc., have different requirements for the fluidity and drying speed of inks, and need to be accurately adapted.
Ink preparation
Stir the ink thoroughly before use to ensure that the pigments, solvents and additives are evenly dispersed to avoid precipitation affecting the printing quality.
Parameter adjustment
According to the substrate material (paper, plastic, metal, etc.) and the printing effect requirements, adjust the ink supply, printing pressure, drying temperature and other parameters on the printing equipment.
Printing Operation
When everything is ready, start the printing equipment for printing. In the printing process, pay close attention to the transfer of ink and printing quality, and adjust the parameters in time.
3. Maintenance and repair
(1) Maintenance
Cleaning of printing equipment
After each printing, use a special cleaning agent to clean the ink fountain, ink path system, printing plate cylinder and other parts of the printing equipment in time to prevent the ink residue from drying up and affecting the normal operation of the equipment next time.
Ink storage
Store unused environmentally friendly solvent inks in a cool, ventilated and dry environment, avoid direct sunlight and high temperatures, and prevent solvent volatilization and ink deterioration.
Regular inspection
Regularly inspect the transmission parts and electrical systems of the printing equipment to ensure the stable operation of the equipment, and find and solve potential problems in time.
(2) Maintenance
Blocked ink path
If the ink path is blocked, you can use a suitable cleaning agent to rinse and dredge. For stubborn blockages, the relevant parts need to be disassembled for cleaning.
Printing quality problems
If there are printing quality problems such as color deviation and dot expansion, check the formula of the ink, the printing parameters and the mechanical accuracy of the equipment, and investigate and solve the problems one by one.
Equipment failure
When there is a mechanical failure or electrical failure of the printing equipment, it will be overhauled by professional maintenance personnel and replaced with damaged parts.
4. Advantages
Strong environmental protection
The use of eco-solvent ink greatly reduces the emission of volatile organic compounds (VOCs), reduces the pollution of the atmospheric environment, and protects the health of operators.
Fast drying
Fast drying speed, can adapt to high-speed printing production line, improve production efficiency, reduce energy consumption.
Bright color
It has good pigment dispersion and stability, high color saturation, clear and delicate printing patterns, and excellent visual effects.
Wide compatibility
It has good affinity with a variety of substrates, and can achieve high-quality printing on different materials.
5. The benefits of customer choice
Cost savings
High-speed printing and low energy consumption reduce production time and energy costs, reduce the frequency of equipment cleaning and maintenance, and also save maintenance costs.
Quality improvement
Excellent color performance and firm adhesion can improve the quality and grade of printed matter and enhance market competitiveness.
Green image
The use of environmentally friendly solvent inks helps enterprises establish a green image and meet consumers' needs for environmentally friendly products.
6. Industry application
Food packaging printing
Because it is environmentally friendly and non-toxic, it is widely used in the printing of food packaging bags and packaging boxes to ensure food safety.
Label printing
Printing on all kinds of product labels, the color is long-lasting, not easy to fade, and meets the requirements of environmental protection.
Publication printing
It used for the printing of books, magazines, etc., which not only ensures the printing quality, but also reduces the harm to readers and the environment.
Electronic product packaging printing
To meet the dual needs of electronic product packaging for exquisite appearance and environmental protection.
7. Future development prospects
With the increasingly strict environmental protection regulations and the continuous improvement of consumers' awareness of environmental protection, the market for environmentally eco-solvent inks has broad prospects. In the future, R&D will be committed to further optimizing ink formulations, improving ink performance and reducing production costs. At the same time, in emerging fields such as degradable packaging printing, intelligent packaging printing, etc., environmentally friendly solvent inks are expected to open up more applications, continue to promote the green transformation of the printing industry, and provide strong support for the sustainable development of various industries.
