Abstract
In a ballistic aerosol marking device or the like, marking material flows from a material reservoir to a delivery channel via a port. The walls of the channel and or the port may be provided with a non-wetting coating to allow for control of the position of a meniscus formed in or at the port. By controlling the meniscus location, attributes of the system, such as the quantity of marking material delivered to the channel, the size of the marking material droplets delivered to the channel, the amount of foreign material (e.g., carrier liquid) delivered to the channel with the marking material, the field strength of gating electrodes, etc. may be controlled.
