Abstract
According to aspects of the embodiments, there is provided process and apparatus to use additives with the clear wetting agent to aid in detection of defective substrates or missing jets. For light colored substrates, dye can be used for darkening of the wetting agent to provide sufficient contrast for defect detection. For dark colored substrates, the dye could be a specific color that a sensor is tuned for. An additive that glows only in the presence of a specific wave length of light could be utilized for any color substrate. By comparing the detected pattern to the desired pattern, end product voids can be greatly reduced or eliminated.
