1. An ink-based digital printing dampening fluid delivery system useful for printing with an ink-based digital printing system, the ink-based digital printing system having an imaging member, the system comprising: a supply chamber having a supply chamber interior;a supply channel, the supply channel defining a supply channel interior in communication with the supply chamber interior, the supply channel descending towards the imaging member at an angle of 30 degrees or less, the supply channel being configured to deliver fluid vapor onto a surface of the imaging member; anda supply channel outlet configured to enable the supply chamber interior to communicate with the surface of the imaging member, the supply channel outlet being configured to deliver dampening fluid vapor to the surface of the imaging member at an angle of 30 degrees or less by vapor deposition, the supply channel including line probes configured to report tangential velocity above a plate surface, mass fraction at the surface of the plate, and temperature at the surface of the plate. 2. The system of claim 1, comprising: a manifold gap, the manifold gap being defined by supply channel and the surface of the imaging member. 3. The system of claim 1, wherein the surface of the imaging member comprises a printing area, the printing area having a width, the system comprising: a supply chamber diameter, the supply chamber being configured to form a tubular shape, the supply chamber cross sectional area being 1.25 times the supply channel cross sectional area or larger. 4. The system of claim 1, comprising: a manifold gap, the manifold gap being defined by a distance between the supply channel and the surface of the imaging member, the supply channel interior configured to deliver fluid vapor onto a surface of the imaging member having a width substantially equal to the manifold gap. 5. The system of claim 4, wherein the manifold gap is substantially the same upstream and downstream of the supply channel outlet, with respect to a process direction of the imaging member. 6. The system of claim 1, wherein the surface of the imaging member comprises a printing area, the printing area having a width, the system comprising: a manifold gap, the manifold gap being defined by supply channel and the surface of the imaging member; anda supply chamber diameter, the supply chamber being configured to form a tubular shape, the supply chamber cross sectional area being 1.25 times the supply channel cross sectional area or larger. 7. The system of claim 6, wherein the manifold gap is substantially the same upstream and downstream of the supply channel outlet, with respect to a process direction of the imaging member. 8. The system of claim 1, wherein the supply channel outlet is configured to deliver dampening fluid vapor to the surface of the imaging member at only an angle of 30 degrees or less by vapor deposition.
