Patent number: 11780239Abstract: A method of controlling a system including an arrangement of at least two nozzles, wherein the arrangement and the shape move relative to each other, each nozzle traces a respective path on the shape, and each nozzle is configured to jet drops at actual jetting locations along the respective path of the nozzle. The method results in sequence of actuation events received from a control signal to be more frequent than would be needed for an arrangement printing on a flat surface to produce the required dot resolution. It is then possible to select which of the individual nozzles are to jet for a given actuation event from the sequence so that the actual jetting locations deviate from the target jetting locations by no ore than a define maximum error distance.Type: GrantFiled: May 13, 2021Date of Patent: October 10, 2023Assignee: Global Inkjet Systems LimitedInventors: Philip Collins, Nicholas Campbell Geddes, Damian Howard Laurence Smith

Patent number: 11633961Abstract: A method of controlling a system including a printhead for printing an image on at least one surface, wherein the at least one surface differs in shape from a nominal surface by a known tolerance, and wherein the printhead and the at least one surface move relative to each other along a predetermined print path comprising at least one swathe. Small dot patterns (referred to as “pathfinders”) are printed on a surface of the object in a preliminary printing pass, then the printed dot patterns are analyzed, for example with a machine vision system. The necessary corrections may then be calculated from this analysis and applied to a subsequent full printing pass.Type: GrantFiled: May 14, 2021Date of Patent: April 25, 2023Assignee: Global Inkjet Systems LimitedInventors: Philip Collins, Nicholas Campbell Geddes

Publication number: 20130074765Abstract: 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.Type: ApplicationFiled: May 27, 2011Publication date: March 28, 2013Applicant: INCA DIGITAL PRINTERS LIMITEDInventors: Philip Heylen, Nicholas Campbell
