Abstract
In an ink jet printer (2), where there is relative movement between a print carriage (4) and a print table (6) to print on to a substrate mounted on the table (6), the gradient of the print table at each position of the print carriage (4) is used to produce a compensated position of the print carriage (4), and printing data is sent to the print head according to the compensated position instead of the actual position. This delays or advances the release of ink, to compensate for the difference in the time taken for the ink to reach a substrate mounted on the print table (6) when the print gap between print heads and print table (6) is not constant.
