A system for laying down stripes of solution on substrate is described. The substrate preferably comprises a web of material set on a backing roller passed by a specially configured die. The die includes at least a mouth with lips extending beyond a face or body of the die. The die is adapted to avoid fluid leakage therefrom. Upper and lower portions of the die defining the mouth are preferably substantially flat and minor images of each other. The lips are preferably placed in close proximity to the material on which the solution is to be deposited. Solution passing through the mouth of the die is directed to the webbing and deposited in a substantially constant thickness stripe or band. Often, the solution comprises a reagent-type solution. The solution coating is typically dried onto the substrate. Dried product may then be used in reagent test strip production.
