A printing arrangement and a printing method for two-sided printing on a recording medium are disclosed, in which conditioning by steam and/or liquid droplets takes place after printing on the first side of the recording medium. Because of the conditioning, damage is avoided to the print image of the first side during subsequent printing on the second side, without the recording medium being impaired by the conditioning.

Printing arrangement for two-sided printing on a recording medium and printing method

A printing arrangement and printing method are disclosed for two-sided printing on a recording medium, in which intermediate fixing by superheated steam takes place after printing on the first side of the recording medium. Owing to the intermediate fixing, damage to the print image of the first side during subsequent printing on the second side is avoided without the recording medium being impaired by the intermediate fixing.

In a device or method to fix print images on a recording material, a printing fluid comprising a carrier fluid and chromophoric solid particles are applied to the recording material, the chromophoric solid particles being applied in a form of the print images to be fixed. Hot waste gas and infrared radiation are generated with aid of a porous burner. The infrared radiation is directed towards the recording material in a drying chamber such that the carrier fluid polymerizes or is vaporized, whereby a gaseous air/oil mixture arises in the drying chamber. The air/oil mixture is influenced with aid of the hot waste gas of the porous burner.
