Static eliminator bar prevents UV fogging

One of the main reasons for poor quality UV printing is image "fogging", caused by electrostatic charges on the substrate.

Large-format digital UV printing is a growth market where the quality of print must be of the highest order.

One of the main reasons for poor quality printing is image "fogging" caused by electrostatic charges on the substrate.

The powerful fields generated by the static charge causes the tiny ink droplets to be deflected onto nonimage areas on the substrate.

This results in poor quality print and a rejected product.

There are various reasons for the generation of the static charge on the substrate.

During 2007 an in depth study of the digital printing process and "fogging" phenomenon at Fraser Anti-static Techniques of Bampton, Devon has led to the development of static elimination systems to overcome these problems.

The 1250-S Static Eliminator Bar mounted onto the travelling print head can prevent this phenomenon.

Anti-static systems are also available for removing the dust from the substrate.
