Abstract
A diagnostic system for measuring inkjet printing system performance includes a printhead that deposits a colorless precoat solution from one or more of a plurality of ejector jets. The diagnostic system includes a diagnostic sheet, having a substrate, and a layer of material disposed on a first surface of the substrate, where the layer of material changes color after contacting the precoat solution, and an image scanner configured to capture a pattern on a surface of the diagnostic sheet after the precoat solution is deposited. The layer of material of the diagnostic sheet may include a moisture sensitive composition or a pH indicator. A method includes providing a diagnostic sheet to an inkjet printing system, where the diagnostic sheet may include a layer of material that changes color after contacting a precoat solution, and when needed, correcting one or more jetting operations.
