A number of methods may be utilized to correct for the first drop dissimilarity in drop-on-demand inkjet devices. Various collection processes, mass calculations and timing manipulation may be utilized to correct the first drop dissimilarity problem.

First drop dissimilarity in drop-on-demand inkjet devices and methods for its correction

A method for improving the morphology of drops ejected from inkjet dispensers results in a more accurate and repeatable process. The method involves shifting the dwell time from one corresponding to the first harmonic of the dispenser to a higher harmonic, for example, the third harmonic.

Method for improving drop morphology of drops ejected from an injet device

A method for determining either the mass of one or more drops dispensed from an inkjet dispensing device or the concentration of dissolved solutes form one or more drops of a liquid of interest dispensed from an inkjet dispensing device utilizes UV visible spectroscopy. The UV absorption spectra of the constituents of the solution may be compared to predetermined calibration curves to accurately determine mass and concentrations of a single drop.

Quantitation and analysis of droplets ejected from an inkjet device

The establishment of a stable acoustic environment within the individual channels of an inkjet printing device functions to allow the inkjet printing device to precisely deposit the same amount of a particular substance at one or more locations on an object. This is particularly relevant when the inkjet printing device is operated in the on-demand mode of operation.
