More Information
Summary:There is described a method of operating an aqueous ink jet printing apparatus. The printing apparatus includes a member defining a reflective imaging surface wherein the imaging surface is substantially white or grey in the visible spectrum and wherein the imaging surface has an optical density variation of less than about 0.3. The method includes a photosensor array disposed to receive light reflected from the reflective imaging surface. The method includes ejecting aqueous ink onto the reflective imaging surface using a printhead and forming aqueous ink drops on the surface of the rotating member. The method includes generating image data from the reflecting imaging surface using the photosensor array. The method includes identifying a parameter from the generated image data that is not within specification
