WEKO RFDi

The electrophotographic printing process using a Xeikon machine requires heat, not only to fuse the toner unto the substrate but also to condition the material prior to printing. This heat will inevitably result in partial evaporation of the moisture present in the printed substrate. To reintroduce the vaporized moisture, the WEKO RFDi remoisturizer unit can be placed behind the press. The amount of moisture in the production environment differs from the moisture content in the printed material exiting the press. In order to reduce the risk of waviness, the printed substrate is moisturized immediately after printing using the WEKO RFDi unit. Print jobs will be more or less reactive to this, depending on the substrate, the structure of the media, the coating and the thickness.
