Digital document printing is a major market for us. The process dries out the substrate to make it very static generative. The high speed can cause static generation at every roller or stage, in addition to the static induced by the process itself. This problem can be seen immediately at the exit of the printer or at subsequent operations, such as creasing and folding. Some problems can be severe, especially with synthetic substrates. We use a wide range of equipment to solve these problems. Some typical solutions are shown on this page.
The product is usually charged as it exits the printer. This may, or may not, be a problem depending on the immediate post-printing operation and the substrate.
A 1250-S Bar positioned 25-50mm from the substrate can remove this charge.
There can be a wide range of subsequent operations: bursting, creasing, folding, collating and mailing. If the paper has had the opportunity to regain some moisture fewer problems will arise, but some substrates are resistant to water absorption and so the static charge will not go away.
Digital printing processes are also used on synthetic substrates in a wide range of markets.
