Plasma surface treatment is a technique used in inkjet printing to improve the adhesion of ink to a substrate. Inkjet printing is a non-contact printing process where droplets of ink are ejected from a print head onto a substrate. However, the ink droplets may not adhere well to certain substrates, which can result in poor print quality and smudging.
Plasma surface treatment involves exposing the substrate surface to a low-pressure plasma. The plasma generates a range of reactive species such as ions, radicals, and photons that can modify the surface chemistry of the substrate. This modification can improve the surface energy and wettability of the substrate, making it more receptive to the ink droplets.
Plasma surface treatment can be used on a variety of substrates, including polymers, metals, and ceramics. It is a non-contact process that can be performed at ambient temperature and pressure, making it a convenient and cost-effective method for improving ink adhesion in inkjet printing.
One of the key advantages of plasma surface treatment is that it does not require any additional chemicals or solvents, which can be harmful to the environment. It is also a fast and efficient process that can be integrated into existing inkjet printing systems with minimal modifications.
No need to use high-adhesion ink (which is a kind of consumables), which can effectively reduce your cost.
Combined with various types of plasma generators and spray heads, customers can experience a new and economical prepress technology for different products.
Improve the hydrophilicity of the surface of the material, and enhance the adhesion of the ink on the surface, so that the ink never falls off.
Plasma equipment can be directly installed on the automatic folder gluer, and processed online without affecting the existing process.
Overall, plasma surface treatment is a valuable technique for improving ink adhesion in inkjet printing, which can result in higher quality prints and more efficient printing processes.
