Abstract
An apparatus for the production and repair of color filters from a substrate on which is deposited a regular network of color blocks. The apparatus includes a very stable Table 23 supporting the substrate and a printing head 25 using a high resolution, continuous ink jet with one or more nozzles supplied by an ink circuit. A mechanical motor driven device 28 provides for the relative displacement of the substrate 24 with respect to the printing head 25 and a measuring device 300 measures the position of the Table 23 by laser interferometry or by optical encoding. Ink positioning system 34 positions ink droplets using microscopic optics and a system inspects and controls the complete apparatus.
