1. How Does UV Inkjet Printing Work?

 

UV inkjet printing is a non-contact printing technology that uses ultraviolet-curable ink to produce text, graphics, barcodes and other variable information on product surfaces.

 

During printing, ink droplets are deposited onto the substrate through a printhead. An integrated UV curing system then exposes the ink to ultraviolet light, initiating rapid polymerization and curing.

 

Compared with conventional Inkjet Printing,UV inkjet technology offers several potential advantages:

 

Rapid curing: UV ink can cure almost immediately under suitable conditions, reducing waiting time between production processes.

 

High-resolution printing:Suitable for fine text, logos, barcodes and QR codes, depending on the printhead and printing configuration.

 

Versatile material compatibility:Can be used on selected plastics, glass, metals, coated paper and other substrates.

 

Improved print durability: Properly selected ink and curing conditions can provide good adhesion and resistance to abrasion.

 

Flexible variable-data printing:Supports production dates, batch numbers, serial numbers, barcodes and QR codes.

 

Actual printing performance depends on the substrate, ink formulation, curing conditions and production environment.
