A multipass large format flat bed inkjet printer (1, Fig.1) for printing an image on a substrate is described. The printer (1, Fig.1) has a print carriage 8 for supporting an array of printheads 18 adjacent the substrate 6 during printing; a bed (4, Fig.1) for supporting the substrate 6 during printing; and a movement mechanism (5, Fig.1) for providing relative movement of the print carriage 8 and the substrate 6 in a print direction during a print pass. The print carriage 8 is such that the width of the array of printheads 18 transverse to the print direction is at least substantially the full width of the image. The printheads 18 provide an array of nozzles (22, Fig.3) which is substantially continuous across the array of printheads 18. The arrangement may be such that the distance of movement of the print carriage 8 in the indexing direction during printing of an image is less than 10%, preferably less than 5%, of the width of the printhead array in the indexing direction. The printer (1, Fig.1) may be used to print an image using curable print material. There is also provided an alignment system for use in the alignment of printheads 18 in the printer (1, Fig. 1), the system comprising a plurality of printhead moving devices (50, Fig.10a) for moving the printheads 18. |
