Abstract

A suction device (200) for an inkjet printing device (100) is described, which is designed to guide a printed recording medium (120) along a transport direction (1) through a constriction (202) with a counter-rotating gas flow (204) in order to be able to suction off aerosol (170) in the transport direction (1) upstream of the constriction (202). The constriction (202) is formed in an efficient, flexible, and precise manner by a guiding unit (300) which acts on the back of the recording medium (120) at the constriction (202).
