Jet printing apparatus in which a second electrode structure (17, 19; 33, 34) is located between the conventional droplet deflecting electrodes (17, 18; 31, 32) of the apparatus and the surface (15) being printed, to alter the trajectory of scanned droplets (14) so that they strike the surface (15) substantially orthogonally to the plane of the surface. This enables good registration of patterns produced byjet printing on to wide fabrics, carpets and the like, using widely deflected droplets (14), even if the surface (15) being printed is a non-smooth surface or becomes wrinkled as it passes through the printing apparatus. |
