Patent ID: 7544390

Claim:
A method for imaging a pattern or design on a transparent glass sheet having inner and outer surfaces, the method comprising: providing a stencil, the stencil having open portions and a backing, together defining the pattern or design; applying the stencil to a surface of the transparent glass sheet; and providing a transparent surface smoothing composition to the glass surface such that the composition contacts the glass surface through open regions of the stencil so as to transfer the pattern or design to the glass sheet to form a coated portion having substantially the same index of refraction as the glass sheet such that the pattern or design is not visible and the coated portion of the sheet is visually indistinguishable from an uncoated portion without a presence of moisture, wherein the pattern or design is imaged upon the glass surface as the glass surface is transitioned from a colder temperature to a warmer temperature thereby providing conditions for condensation droplets to form, the pattern or design imaged as a result of greater presence of condensation in contrast to lesser presence or absence of condensation.
