Abstract
A focused spray jet printing system according to an exemplary embodiment of the present invention may include an atomization unit which atomizes ink by a carrier gas to make generate atomization droplets; a head unit including a virtual impactor which uniformizes sizes of supply atomization droplets ejected from the atomization unit to eject uniform atomization droplets; a focusing unit which is provided in the head unit to focus the uniform atomization droplets introduced into the head unit with sheath gas to spray the uniform atomization droplets onto a substrate; a sheath MFC which supplies the sheath gas, and a valve unit which is selectively connected to any one of an atomization droplet flow path which is formed in the head unit to flow the uniform atomization droplets to connect the virtual impactor and the focusing unit and a flow path formed at the outside of the head unit to flow the sheath gas.
