Method of mitigating variations in a print gap

Methods for mitigating variations in a print gap are described, the print gap comprising the distance between the surface 512 of a printer table 510 and printing means, such as a printhead 518. The print gap is first measured before at least one layer of ink is printed using the printing means 518 at a selected position based on the measured print gap. The thickness of the layer of ink is selected to mitigate the variations in the print gap. In some embodiments, a substrate support surface (522, Fig.5b) may then be arranged over the printer table 510, so that the printed layer is disposed between the printer table and the substrate support surface. The apparatus can compensate for variations in the print gap due both to irregularities in the printer table surface 512 and misalignment in mounting of the printing means 518. The print gap may be measured using a laser sensor 520. Also described is a printer table 510 produced according to the methods described.

PROTECTION OF NEWLY PAINTED SURFACES

A newly painted surface is protected by applying over the surface a film (105) of a non-adhesive clinging plastics material. This allows the paint to dry through it and prevents sticking against any contacting surface. The film (105) is subsequently removed.

Method of adjusting surface topography

Methods for adjusting the topography of a surface, such as for making a support surface substantially flat, e.g. for mitigating variations in a print gap, are described. The topography of the surface is first measured, and then a shim layer is printed to approximate the topography to a reference topography, the thickness of the layer being calculated using the measurements. For example the print gap comprising the distance between the surface of a printer table and printing means, such as a printhead. The print gap is first measured before at least one layer of ink is printed, using the printing means, at a selected position based on the measured print gap. The thickness of the layer of ink is selected to mitigate the variations in the print gap. In some embodiments, a substrate support surface may then be arranged over the printer table, so that the printed layer is disposed between the printer table and the substrate support surface. The apparatus can compensate for variations in the print gap due both to irregularities in the printer table surface and misalignment in mounting of the printing means. Also described is a printer table produced according to the methods described.
