<p>An apparatus for fabricating printing plates (15), e.g. lithographic or offset printing plates. The apparatus comprises processing means for digitizing an image, at least one assembly having at least one ink jet printing head (12) and operatively connected to the processing means, control means (11) operatively connected to the processing means and the assembly for supplying digital information to the assembly to project the digitized image upon the printing plate (15), and drive mechanisms (17, 18) operatively connected to the control means (11) and the assembly for controlling ink jetting movement of the printing head (12). An x-y table (14) is preferably also present for carrying the printing head (12) for planar movement with respect to the printing plate (15). The movement of the table (14) permits the printing of multiple pages (16a, 16b, 16c) upon large lithographic plates (15).</p> |
