A print head comprising a plurality of chip-like tiles (10) arranged on a common substrate (14), each tile having a front face (16) with an array (18) of recording elements disposed in the front face (16) in a predetermined pattern, and a generally rectangular contour with a cut-out (40) formed at at least one of its four corners, each cut-out being delimited by two reference-defining walls (42, 44) extending normal to one another and to the front face (16) and serving as a reference for positioning the tiles (10) on the substrate (14) so as to establish a predetermined positional relationship between the recording elements of the different tiles, characterized in that the substrate (14) has a plurality of recesses (12) accommodating each at least a part of a tile (10) and having side walls that define engagement surfaces (46, 48) for each of the reference-defining walls (42, 44) of each tile, the substrate (14) is formed of a material that is suitable for photo-lithographic processing, and the engagement surfaces (46, 48) of the substrate (14) are surfaces formed by photo-lithographic techniques. |
