The function and application of lecithins in printing plants
Lecithins are a group of natural compounds that play an important role in many industrial applications. Lecithins have become indispensable, especially in the printing industry, as they perform several crucial functions. In this blog post, we shed light on the properties of lecithins and their specific applications in printing plants.
Was sind Lecithine?
Lecithins are phospholipids found in the cell membranes of animals and plants. They consist mainly of phosphatidylcholine, phosphatidylethanolamine and phosphatidylinositol. These compounds have amphiphilic properties, meaning they have both hydrophilic (water-attracting) and lipophilic (fat-attracting) proportions. These properties make lecithins excellent emulsifiers and dispersants.
The Function Of Lecithins In The Printing Industry
In the printing industry, lecithins perform several important functions that contribute to improving the quality of printing and the efficiency of printing processes:
1. Emulgation and Stabilization:
Lecithins act as emulsifiers that allow the mixing of water-based and oil-based components in printing inks. They help to form stable emulsions, which are necessary to achieve uniform and high-quality printing results.
2. Improvement of viscosity:
The viscosity of the printing ink is crucial for the printing process. Lecithins can affect and adjust the viscosity to ensure optimal fluidity of the color. This leads to better control during the printing process and prevents problems such as clogging or uneven application of paint.
3. Wetting and dispersing:
Through their wetting properties, lecithins improve the distribution of pigments in the printing ink. They ensure that the pigments remain evenly dispersed and prevent clumping, resulting in a consistent and uniform print image.
4. Antistatic Properties:
Lecithins can also act as antistatic agents by reducing the static charge of the printing inks and materials. This is especially important in high-speed printing processes, where static charges can cause malfunctions and quality problems.
Application of lecithins in printing plants
The application of lecithins in printing plants is carried out in several ways, depending on the specific requirements of the printing process:
1. Offset printing:
In offset printing, lecithins are used to optimize the balance between hydrophilic and lipophilic components. This is crucial because offset printing is based on the repulsion of water and oil to produce a precise print image.
2. Flexo printing:
In flexo printing, which is often used for packaging and labels, lecithins help stabilize the flexible printing inks. They improve the adhesion of the paint on different substrates and provide a uniform color coverage.
3. Digital printing:
In digital printing, where different types of ink are often used, lecithins help to stabilize the ink formulation. They prevent separation of the ink components and ensure constant print quality.
Conclusion
Lecithins are indispensable in the printing industry due to their versatile properties and ability to cope with various challenges in the printing process. Their application ranges from improving emulsification and viscosity to stabilizing and dispersing pigments. Through the targeted use of lecithins, printing companies can increase the quality of their printed products while improving the efficiency of their production processes.
