Corona Treaters for
Digital Print & Finishing
Surface treatment might be only an ancillary part of the overall production process, but it’s one of the most vital links in the chain if you are dealing with polymeric or foil substrates. Poor corona coverage will pose quality issues downstream, leading to increase production costs for the printer / convertor
Corona treaters for surface enhancement of a wide range of substrates are standard practise for several digital print & finishing lines whether you are coating, laminating, varnishing increased wetting of the substrate improves adhesion bond strengths resulting in a superior finish and end product. Even substrates that have been treated prior to delivery can cause issues if the surface tension / dyne level has decreased due to time, heat or humidity. This will prevent optimum running of your production process, increasing costs per metre run. By corona treating all substrates in-line, a one-off purchase, you can be confident of perfect results every time.

Sheet Fed Corona Supplies have an "off the shelf" solution for corona treating sheets on digital print & finishing lines. Our standard design is based around the B1 size sheet allowing a throughput of up to 4000 sheets per hour.
It is important to note that the sheets must be travelling individually when they pass through the corona treater, to ensure the whole surface of the sheet is exposed to the corona discharge.
Custom design Corona Supplies offer customised solutions for the digital print & finishing market. From single sheets to high speed webs Corona Supplies can design a solution to suit your application.
