Abstract:
1. A method for depositing a liquid with an inkjet printhead on a substrate on which a structure is provided, which structure bounds a number of areas, the method comprising: depositing substantially in each area an amount of liquid with an inkjet printhead forming the structure; observing the structure as it is being deposited on the substrate and producing a signal correlated with the position of each area bounded by the structure; and controlling the displacement of the printhead and timing the delivery of liquid by the printhead on the basis of the signals, wherein observing the structure and producing the signal occur simultaneously while (i) processing the signals, (ii) controlling the displacement of the printhead, and (iii) timing the delivery of liquid during relative movement of the substrate with respect to the printhead during substantially a whole process time of delivering liquid into the respective areas on the substrate bounded by the structure.
