A dispenser for dispensing, along a deposition direction, a solution to a surface when movement occurs between the dispenser and the surface along the deposition direction and when the solution forms a meniscus between the dispenser and the surface, the dispenser comprising:
- a dispensing slot having a slot opening immediately adjacent to the surface when the dispenser is in use, the slot opening having a length at least nominally perpendicular to the deposition direction and a width at least nominally parallel to the deposition direction, wherein the length of the slot opening is at least 2 times the width of the slot opening and the slot opening is continuous and unobstructed along the length of the slot opening;
- and
- a force-balancing reservoir fluidly communicating with the dispensing slot along the length of the slot opening of the slot and designed and configured to hold a portion of the solution during use of the dispenser, the force-balancing reservoir containing a plurality of wetting features deployed to:
- allow the solution to flow out of the slot opening when movement exists between the dispenser and the solution in the dispensing direction;
- and
- keep the solution from flowing out of the slot opening when no movement exists between the dispenser and the surface in the dispensing direction.
