Abstract: A method for depositing a volume of fluid relative to a surface to produce a droplet relative to the surface comprising the steps of forming a bolus of liquid relative to a dispensing member, causing the bolus of liquid to make contact with a surface thereby forming a bridge of liquid between the dispensing member and the surface, and retracting only a portion of the bolus of liquid to break the bridge of liquid between the dispensing member and the surface thereby depositing a droplet on the surface. A volume of a droplet can be adjusted by forming a bridge of liquid between a dispensing member and a surface that includes an initial droplet and breaking the bridge of liquid while leaving a remaining droplet of a different volume than the initial droplet.
